ArcGIS Desktop 10.x training
Introduction to ARCGIS
ArcGIS 10.x is a desktop Geographic Information System from ESRI (Environmental System
Research Institute). There are three licensing levels offered for ARCGIS, each with increasing
capabilities: ArcView, ArcEditor, and ArcInfo.
ArcMap is the major mapping component in ARCGIS.
The other components of ARCGIS are ArcCatalog, ArcScene and ArcGlobe.
During this introduction you will be familiarizing yourself with ArcMap and ArcCatalog
(ArcScene and ArcGlobe are 3D visualization components which will not be covered here).
ArcMap – this component allows you to display, analyze and edit spatial data and data tables.
ArcMap is most often used to make maps. ArcMap is the component we will mainly work with,
during this introduction to GIS
ArcCatalog – this component allows you to browse and manage spatial data files. It works in a
way similar to Windows Explorer but specialized for GIS data. ArcCatalog can be run as a
standalone application or as ArcCatalog window in ArcMap

What is GIS
GIS stands for Geographic Information System.
The following links are to documents that shine a light on what GIS is and what it can do.
The ESRI approach:

1 GETTING TO KNOW ARC MAP
ArcMap is a tool for creating, viewing, querying, editing, composing, and publishing maps.
ArcMap works with map documents. A map document is a collection of links to different spatial
data layers and tables, along with instructions for how the layers will be displayed.
Exercise 1.1: Open and Save a map document
Launch ArcMap
1. From the windows taskbar, click Start, All Programs, ARCGIS, ArcMap 10.
2. In the resulting ArcMap – getting started window, click existing Maps and
Browse for more.

8
Open an existing map document
1. Browse to C:reu_2011map_documents
2. Click the Introduction to ArcMap.mxd icon and click Open.
The Introduction to ArcMap.mxd opens in ArcMap, showing a map of eastern Kansas including
Kansas City, Lawrence, Topeka and two Indian reservations in Kansas. The map also shows
larger water bodies, County boundaries and state boundaries. The left panel of the ArcMap
window is the table of contents (TOC). It serves as a legend for the map (it also has other uses
which we will discover later).The TOC also shows the order in which the layers are drawn. Here
the order in which the map layers are drawn is: Background, State County Outlines, Water. Map
layers which are not checked (checkboxes to the right of the layer name in the TOC) are not
shown in the map.
You also see the menu bar and the standard toolbar in the upper part of the ArcMap window. The
tools toolbar should be floating on the right side of the screen and can be docked somewhere on
the interface (many people dock it next to the standard toolbar).

9
Save the map document to a new location
You will save all files you modify or create while working through the tutorial in the
C:reu_2011student folder.
1. In the menu bar click file,
save As.
2. Navigate to the
C:reu_2011student folder
and save the map as
Introduction to ArcMap.mxd.
3. Click save.

Exercise 1.2: Working with map layers
Map layers are references to data sources such as point, line, and polygon shapefiles, geo-
database feature classes, raster images, and so forth representing spatial features that can be
displayed on a map (ESRI, GIS Tutorial).
Map documents do not store the features and tables of the data sets within the map
document. Instead, the map stores the name and disk location of the spatial data. Changes to
the map document do affect the source data except for specific actions such as adding fields or
editing shapes.
Because the source data are stored outside the map document, changes to source data made in
one map document affect all map documents using the same data set. The storage of the map
document and the source data in separate locations also has implications for sharing map
documents. Giving a colleague a copy of a map document only works if he or she has access to
exactly the same data in the same disk location as the original user. The best way to share a
document is to place the map document in the same folder as the data, and share the entire folder.
Turn a layer on and off
This is a crucial function of a GIS. Before GIS existed, mapmakers would create maps by
overlaying clear plastic sheets which had single map layers like contour lines, roads, or water-
bodies drawn on them (ESRI, GIS Tutorial).
1. Click the small check box to the left of the Native American lands layer in
the TOC to turn that layer on.
If the TOC accidentally closes, click windows, Table of Contents to reopen it.

11
2. Click the check box again to turn the layer off.
Add and remove map layers
You can add more layers to the map in different ways.
1. Click the Add data button
2. In the data browser, click the connect to folder button .
3. Under computer find the c drive, navigate to the REU_2011 folder and click
OK.
This will create a permanent shortcut to the REU_2011 folder.
4. In the Add Data window, navigate to the GIS_datausa folder
5. Double-click the US_populated_places.shp file.
ArcMap adds the US populated Places shape-file to the Map and the TOC and assigns a random
symbol for the features.

12
6. Right-click US_populated_places in the TOC and click Remove.
This removes the map layer from the map document but does not delete it from its storage
location.
7. Click the Catalog window button in the standard toolbar.
This will open the ArcCatalog window on the right side of the screen. ArcCatalog allows you to
explore, maintain, and create GIS data files with its many ArcCatalog utility functions. From the
ArcCatalog window you will drag and drop a map layer into the TOC as an alternative method of
adding data.
8. In the Catalog window, click on folder connections and navigate to
c:REU2011 GIS_dataUSA and click the US_populated_places.shp layer.

13
9. Drag and drop the US_populated_places into the top of the TOC window.
10.Use the Auto Hide button in the catalog window to auto hide the window.
The Auto-Hide button lets you keep application windows (such as TOC, toolbox or the Search
window) available for immediate use, but hides them in between uses so that you have more
room for the map.
Change a layer‟s di
splay order
Changing the order of the map layers in the TOC will change the order in which the map layers
are drawn in the map.
1. Make sure the List by drawing order button is selected in the TOC.
2. Check the Native American Lands layer in the TOC to make it visible.
3. Drag the Native American Lands layer under the background layer in the
USA Base map.

14
The Indian Reservations are not visible anymore since they are covered up by the USA Base
Map.
4. Drag and drop the Native American lands back to the top of the TOC.
Change a layer‟s c
olor
The ability to change the color of a map layer is an important part of the map creation process.
1. Click the Native American lands layer‟s l
egend symbol in the TOC.
The legend symbol is the rectangle below the layer name in the TOC
2. Click the Fill Color button in the Current symbol selection of the Symbol
Selector window.

15
3. Click the Ultramarine tile in the Color Palette (or any other color you like).
4. Click OK.
The layer’s color changes to Ultramarine.
5. Click the Native American lands layer‟s l
egend symbol in the TOC again.
6. From the Styles Panel choose the Hollow style from the ESRI styles.
7. Under Outline Color choose red
8. Change the outline width to 3.
9. Click OK.
The Indian Reservations in the map are now
displayed with a red outline instead of a solid
color.
Now it is your turn:
Use the Symbol selector and its Search function to
Display the US_populated_places layer with
checkered flags and the Native American Lands
layer with the ESRI grassland style.

16
Exercise 1.3: navigate in a map document
Another essential function of GIS is to be able to view map data in different scales and to be able
to move the extent of the map. The tools toolbar lets you zoom in, zoom out, pan, go to full
extends of the map, go to last extend.
Zoom to full, previous and next extent.
1. Click the Full extent button in the tools toolbar .
The map will zoom to the full extent of the data sets.
2. Click the previous Extent button .
The map will be zoomed back to extent of Kansas.
3. Click the Next Extent button .
The map will be zoomed to the full extent again.
The previous and next extent buttons work similar to the back and forward buttons in MS
Internet explorer.

17
Zoom In
1. Click the Zoom in button on the Tools toolbar.
2. Click and hold down the mouse button on a point above and to the left of
your home state.
3. Drag the mouse down to the bottom and to the right of your home state and
release.
4. Repeat steps 1-3 to zoom into the extent of your home reservation.
5. Zoom back to the full extent with the full extent button .
Pan and zoom in/out with scroll wheel
Besides the zoom tools of tools toolbar you can zoom with the scroll wheel of your mouse.
Combined with the pan tool you can direct the focus of the zoom.

18
1. Click the Pan Button .
2. Pan your Home State into the middle of the map.
3. Use the scroll wheel of you mouse to zoom in (scroll backwards).
4. Use the Pan Button and the scroll wheel alternating to zoom to your home
reservation or home town.
Use Bookmarks
Bookmarks let you save extents of map documents which you want to visit again.
1. Click Bookmarks from the menu bar.
2. Click manage.
Make sure you are zoomed into extent of your home reservation or home town.
3. In the Bookmarks manager window click create
4. Enter the name for the bookmark in the Bookmark Name field.
5. Click Ok and close.
You just created a Bookmark for the extent the map has right now.
Now it is your turn:
Use the zoom tools and the Bookmarks manager to create
bookmarks for your tribal College, Haskell and your house. Use
the scale field in the tools toolbar to set the scale for these three
bookmarks to 1:24000.

19
Exercise 1.4: The measuring Tool
You will use the measuring tool to measure the size of your home reservation.
Change measurement units
Maps use coordinate systems to display the earth surface into 2 Dimensions on a piece of paper
or a monitor screen. Frequently the map units used by these coordinate systems are feet or
meters. Regardless of the map coordinate system, you can set the measurement tool to reflect
measures in any units (like miles or kilometers).
1. Zoom to the extent that shows your home reservation.
2. On the tolls toolbar, click the Measure button .
The Measure window opens.
You will now set the measure units to miles and acres.
3. In the Measure window, click the Units drop-down button.
4. Click Distance and Miles.
5. Click the Units drop-down button again.
6. Click Area and acres.
Measure the width and length of you home reservation
1. Click the Measure Line button .
2. Measure the width of your home reservation.

20
The Measure window will show the length of the line.
3. Double click to stop the measuring process
4. Measure the length of your home reservation, double click to end the
measure.
5. Click the Measure area tool .
6. Measure the area of your home reservation, by following the outline of the
reservation with single mouse clicks.
7. Double click to end the measurement.
The measurement window shows the Areas measured in acres as well as Perimeter.
8. Click the measure feature tool .
9. Click the feature you want to measure.

21
Exercise 1.5: Work with feature attributes
To work with feature attributes is one of the most important capabilities of GIS and what makes
it so different from a Database system or simple drawing Software like CAD. GIS brings
(geo)graphic features together with database tables.
You will use tools to view database tables connected to the features on your map, query them
and label the map with the values in the database tables.
Use the Identify tool
To display data attributes of a map feature you can use the
Identify tool. This tool is the easiest way to learn
something about a location on a map (ESRI, GIS Tutorial).
1. Click Bookmarks in the menu bar
2. Click the “lower 48 states” bookmark.
The map will be zoomed out to the lower 48
states of the USA.
3. Click the Identify button in the tools
toolbar.
4. Click on any of the Native American lands.
The identify window will show the attribute data of the
feature that you clicked on.
5. Click the identify from drop-down list and
click Visible layers
6. Click on any of the American lands again
The identify window should now show all the map layers visible at the location you clicked.
7. Click any of the layers listed in the Identify window.
The identify window should now show all attributes of the layer you.

22
Use advanced Identify tool capabilities
You can use the identify tool to navigate and create spatial bookmarks
1. Right click the Native American lands in the list of layers in the identify
window.
2. Choose select from the drop down menu.
The feature you identified earlier is now shown with a bright blue outline, indicating that the
feature is selected.
3. Right click the Native American lands in the list of layers in the identify
window.
4. From the list select zoom to.
The map will be zoomed to the extent of the feature you identified before.

23
The Attribute table
The Attribute table shows you all the data records stored for all the features in a feature class (or
layer). It appears much like a spreadsheet( in MS Excel for example). Each row in the table is
linked to one feature in the layer. Selecting rows (called records) in the table will select a feature
in the layer, deleting a complete row in the table will delete the connected feature in the layer.
1. Click on Bookmarks, lower 48 states.
2. Click the clear selected features button in the tools toolbar.
If the button is ―
greyed out‖ (inactive) there are no features selected and you do not need to do
this step.
3. Right click the Native American lands feature class in the TOC.
4. Click Open Attribute table from the drop down options.
The Attribute Table for the feature class will open up.
5. Right click the header of the Name field.
6. Click Sort Ascending
Next you will highlight the record (or row) in the table that contains the information for your
home reservation.
7. Scroll down the attribute table and click the record selector (gray cells on
the left side of the table) for your home Reservation.

24
If a feature is selected in the attribute table, it also is selected on the map.
8. Close the attribute table.
9. In the table click the Clear Selected Features button .
Select features on the map and see selected records
1. Right click the Native American Lands feature class in the TOC.
2. From the drop down menu choose selection  make this the only
selectable layer.
This step makes sure that only features from the Native American Lands layer will be selected.
3. Click the select feature button in the tools toolbar.
4. With the selection tool active draw a selection box around Montana.
All Native American Lands in Montana should now be selected.
5. Right click native American Lands in the TOC and open the attribute table.

25
The attributes of the features you selected on the map are now selected in the Attribute table. The
selected records are dispersed over the table.
6. Click the show selected records button at the bottom of the table.
The table will now show just the selected records.
The indicator field next to the selected records button should show that you selected 14 out of
760 records.
Labeling features in the map with attribute values
Since each feature in the map layers is tied to a record in an attribute table you can label the map
features with values from these records.
1. Double click the Native American Lands layer in the TOC
2. In the Layer Properties window Click the Labels tab
3. Check the Label features in the layer field
4. Choose the NAME field as label field.
5. Click the Placement Properties button.
6. In the Placement Properties (under the duplicate Labels) choose the
Remove duplicate labels option.
7. Click ok in the placement Properties window.
8. Click ok in the Layer Properties window.

26
The map should now be labeled with the names of the tribes in Montana.

27
Viewing statistics for an attribute field
You can use the statistics function for an attribute field to get statistical values for the values in
the field. If records in the table are selected, the statistical calculations will be done on the
selected values only.
1. Right click the Header of the ALAND and click Statistics.
The Statistics window shows that the Sum of the land area of the 14 selected Native American
Land features is 34300998099 square meters. The conversion factor from square meters to acres
is 4,046.85, which brings the acres to 8475974.67.
Create Layer from selected features
You can now create a layer from the selected features. This will not save a new copy of the data
on disc but rather just display a subset from the original layer.
1. Right click the Native American lands layer in the TOC.
2. Click Selection from the dropdown menu  create Layer from selected
features.
3. Rename the new layer “Montana tribes”.
4. Turn of the Native American Lands layer (uncheck the checkbox).
You should now see the Native Lands in Montana.
5. Click the clear selected Features button in the tools toolbar.
6. Remove the Montana tribe‟slayer from the map.

28
Find features
The find feature in ArcMap lets you find features in the map by entering search words or
phrases.
1. Turn on the US_populated_Places layer in the TOC
2. Click the Find button in the tools toolbar
3. In the Find window enter Shiprock in the find field.
4. Choose US_populated_places from the drop down options for the In field.
5. Click find.
6. In the results field (on the bottom of the Find window) click the Shiprock
record.
The location of Shiprock flashes on the map when you click the result in the find window.
7. Right click Shiprock in the result window.
8. Click select from the drop down options.
9. Right click Shiprock again.
10.Click zoom to.

29
In many cases the find function will result in more than one result. In those cases you can use the
flash function to find the feature you are looking for from the result list.
Select by attribute / Select by location
The select functions let you query features by attributes (Example: ― Select a
ll towns with a
population larger then 100000) or by location ( Example: ‖select all Native Lands in Oregon‖).
You will now use the select functions to select all census designated places with a population
greater than 10000 on Native American Land.
1. Make sure none of the features in the map are selected.
2. Click Selection from the menu bar.
3. Click select by location.
4. Fill in the fields in the select by Location window as follows:
Selection method: select features from
Target Layer: US_populated_places
Source layer: Native American lands
Spatial Selection method: Target Layer feature intersect source layer
feature.
Assignment 1:
1) Use the find tool to find Lawrence (possibly several
Lawrence in the result list) Kansas on the map and zoom
to it and create a bookmark.
2) Use the find tool to find your hometown, zoom to it and
create a bookmark.
3) Save your map as ―find‖ map in the student folder.

30
All Census designated places on Native American Lands in the USA are now selected.
The Spatial selection you used was the (default) ―int
ersect‖.
Under the Help for this tool you will find all spatial operators available for Select By Location
explained ( a glance at these might help you with next ―
Now it is your turn‖).
5. Click OK.
In the following step you will filter out the places that have a population greater than 10000.
6. Click Selection from the menu bar.
7. Click Select by attribute.

31
8. Fill in the fields in the select by Attributes window as follows:
Layer: US_populated_places
Method: Select from current selection !!!!!!!!
(this will create a subset from the already selected features)
Select * from places WHERE: “POP2000”>= 10000
9. Click OK.

32
The resulting map should look similar to the map below.
1. Close the Introduction to ARCMAP document without saving it.
Assignment 2:
1) How many Hospitals are within 50 miles of your home town?
You will find a hospital layer under C:reu_2011GIS_datausalandmarksUSA Hospitals
How far is the closest hospital?
2) How many Acres of Indian Reservation land is located in your home state?
Use the Native American lands layer. This layer contains reservations (COMPTYP =R in
the attribute table) and trust land.
The Attribute ALAND gives you the answer in Square meters.

33
2 MAP DESIGN
Tutorial 2.1: Create choropleth maps
A choropleth map is a map in which polygons are colored or shaded to represent attribute values.
In this tutorial, you will use the Native American Lands data to produce a choropleth map of
Indian Reservations in Minnesota.
Start a new map document
1. On your desktop, click Start, All programs, ArcGIS, ArcMap 10.
2. In the ArcMap – Getting Started window, click New Maps, My Templates,
Blank Map

34

3. Highlight Native_american_land_states and the USA Base Map.lyr (you can
select both by holding the shift key down when selecting)
4. Click Add.
The map document will now show the data you added in its full extend.
In this case it will zoom to the worldwide extent of the ocean layer which can be found under the
USA Base map layer (background).
Setting extent used by the full extent
You can the limit the extent to which the map document zooms when the full extent function is
used.
1. If The USA Base map layer is covering up Native American land layer
switch the order of them in the table of Contents.
2. Zoom to the extent of the continental US.
3. Double Click “Layers” (the data frame ) in the TOC.

35
10.Zoom to a smaller extent (it does not matter where).
11.In the Tools toolbar click the full extent button .
The map will zoom back to the extent of the continental US.
Create a layer for reservations in Minnesota.
So far you used ―
the selection and create layer from selected features‖ process to create a subset
of a feature class. Now you will use a definition query to do the same thing. The advantage of
using definition queries is that query for the subset is going to be stored in the layer properties,
so that you can verify it in the future.
1. Double click the Native American Land States layer in the TOC to open the
layer properties.
2. Click the General tab and change the layer name to Minnesota
Reservations.
3. Click the definition Query tab and click query builder

Using the Layout View
ArcMap lets you create maps which you can print or export as .pdf files or (.jpg) image files
(which you can use in word documents or power point presentations or posters).
Maps do not only consist of the GIS data but also other map elements. As a minimum each map
should have:
- Title
- Legend
- North Arrow
- Scale Bar
Other map elements include: Logos, reports, graphs, disclaimer, path of the mxd file, person who
produced it, date it was produced.
1. Click View in the menu bar
2. From the drop down menu choose .
The main map frame will now show the layout view of your map.

3 Creating a project Geo-database
An important step during your projects will be to put together a project geo-database which will
hold all project related GIS and remote sensing data.
You can think of a Geo-database as a container for all the map layers you need for the project.
Geo-databases store map layers as feature classes or raster datasets.
Feature classes are map layers that represent real world features as points, (poly) lines or
polygons (areas). You worked with feature classes in the previous part of this tutorial. Each of
the graphical features in the feature class is tied to a record (or row of data) in an attribute table
for the feature class.
Raster datasets are image files (like aerial-photos, Satellite images and scanned maps) or surface
data like digital elevation models or hill-shades. These files consist of raster-pixels (square cells)
with values that can represent the color of objects or elevation in the case of digital elevation
models.
3.1 Online Sources for GIS / Remote sensing data
USDA-NRCS Geospatial data gateway:
http://datagateway.nrcs.usda.gov/
USGS Global Visualization Viewer (GLOVIS) for selected satellite and aerial data

Resources from your states:
http://libraries.mit.edu/GIS/data/datalinks/statedataweb.html
3.2 Importing GIS data from other formats
In many cases when you get data for your project from GIS data gateways or from other experts,
the data will be in an exchange format like shape-files, ARCINFO coverage or geo-databases.

49
We recommend that you create a (file based) geo-database for your projects.
If you work on your project in a group it is advisable to create this project database on a shared
drive (like a file server) so that the whole group can use it.
Creating a file based Geo-database
The ArcCatalog window in ArcMap lets you organize your GIS related data. ArcCatalog is also
available as a standalone application. In this exercise you will use both options.
1. To open the ArcCatalog program, click start  all programs  ArcGIS
group  ArcCatalog 10.
ArcCatalog has a look and feel much like Windows explorer. The difference is that ArcCatalog
will only show you GIS related files. Word documents, PDf files, Power point presentations will
not be visible in ArcCatalog.
2. If you do not see the reu_2011 folder under folder connections follow steps
3 through 5.
3. With ArcCatalog open right click Folder Connections.
4. Click Connect to folder.
5. In the connect to folder window navigate to the reu_2011 folder under
Computer c drive.

50
6. Click Ok
7. Expand the c:reu_2011 folder connection folder
8. Right click the c:reu_2011student folder.
9. Click new.
10.Click File Geodatabase.
c

51
The new geo-database should now be showing in ArcCtalog’s right panel.
12.Rename the new geo-database “Project”.
13. Close ArcCatalog.
Importing shape-files and feature classes from other Geo-databases
In the following steps you will import data from a shapefile and another Geodatabase into your
project database.
1. On your desktop, click Start, All programs, ArcGIS, ArcMap 10.
2. In the ArcMap – Getting Started window, click New Maps, My Templates,
Blank Map.
3. Click the ArcCatalog window button from the standard toolbar.
4. In the ArcCatalog window navigate to the c:reu_2011student folder.
5. Right click the project Geo-database.
6. Click import.
7. Click Feature Class Multiple.
8. In the Import feature class window click the Input features brows button
.
9. Navigate to the c:reu_2011GIS_datausa folder and load the
tl_2009_US_aiannh.shp file.

52
10.Navigate to the c:reu_2011GIS_dataworld.gdb and load the latlong and
continent_ln feature classes.
11.Make sure your Feature class import window looks like the picture below.
12.Click OK.
While the import is running, the process will be indicated in the geo-processing task window in
the lower section of your screen.
Once the process is done it will be indicated by a message window.
13.Click the project database in the ArcCatalog to expand the view to its
content.
14.Leave the map document open.

3.3 Map Projections
A map projection is a way to represent the curved surface of the Earth on the flat surface of a
map.
Map projections allow us to represent some or all of the Earth's surface, at a wide variety of
scales, on a flat, easily transportable surface, such as a sheet of paper. Map projections also apply
to GIS data.
There are hundreds of different map projections. The process of transferring information from
the Earth to a map causes every projection to distort at least one aspect of the real world – either
shape, area, distance, or direction (National Atlas
http://www.nationalatlas.gov/articles/mapping/a_projections.html).
ArcGIS classifies different map projections into two types of coordinate systems – geographic
and projected. Geographic coordinate systems use latitude and longitude coordinates for location
on the surface of a sphere while projected coordinates systems use a mathematical conversion to
transform latitude and longitude coordinates to a flat surface (ESRI- GIS Tutorial Basic
workbook / Page 154).

Changing data frame coordinate system / projection on the fly
Although it is important for you to know about coordinate systems, ArcMap is capable of
changing map projections of GIS layers on the fly. That means it is possible to overlay GIS
layers with different projections.
1. Highlight the continent_ln and the latlong feature classes of the project.gdb
in the catalog window.
2. Drag and drop the feature classes into the TOC of the map document.
The map frame should look like the image below.
Next you will establish what coordinate system the data is in.
3. Double click the continent_ln layer in the TOC to bring up the layer
properties window.
4. In the layer properties window click the source tab.
In the data source section you should now see location of the map layer as well as information
about its coordinate system.

55
The continent_ln layer is in the GCS_WGS_1984 coordinate system, which stands for
Geographic Coordinate System (Latitude and Longitude in decimal degrees) in the World
Geodetic system 1984. All GPS units operate in the same system.
5. Click ok to close the layer properties window.
6. Right click Layers (the data frame) in the TOC
7. From the drop down menu choose Properties
8. Click the coordinate Systems tab
9. In the “select a coordinate System” field click predefined
10.Choose Projected coordinate systems / world / aitoff.
11.Click apply
Your map should look like the image below

56
Now it’s your turn:
Try out some of the other projections and see how the map changes.
1. Click ok to close the data frame properties window.
2. From the catalog window select the tl_2009_us_aiannh feature class.
3. Drag and drop the feature class into the TOC.
4. Right click the tl_2009_us_aiannh layer.
5. Choose zoom to layer.
6. Right click the “layers” data frame in the TOC.
7. Select the Coordinate Systems tab.
8. In the “Select a coordinate system” tab click layers.
9. Choose the tl_2009_us_aiannh layer.
10.Click OK.
The map is now projected in the coordinate system of the tl_2009_us_aiannh feature class which
is in the North_american_albers_equal_area_conic projection.

57
11.Leave the map document open.
Choosing the coordinate system for your project.
The two major coordinate systems used in the US are UTM (Universal Transvers Mercator)
based coordinate systems and State Plane Coordinate System.
Depending on the location of your project area and more importantly the coordinate system used
by your main data source you should choose one coordinate system for your entire vector based
data.
The Image below shows the different state plane zones in the continental US.
(From http://geology.isu.edu/geostac/Field_Exercise/topomaps/state_plane.htm)
The following projection types are used in the system:
 Lambert Conformal Conic... for states that are longer east–west, such as Tennessee and
Kentucky.
 Transverse Mercator projection... for states that are longer north–south, such as Illinois
and Vermont.
 The Oblique Mercator projection... for the panhandle of Alaska, because it lays at an
angle.
The units of state plane system can be in feet or meters.

58
From USGS factsheet about The Universal Transverse Mercator (UTM) Grid:
The National Imagery and Mapping Agency (NIMA) (formerly the Defense Mapping Agency)
adopted a special grid for military use throughout the world called the Universal Transverse
Mercator (UTM) grid. In this grid, the world is divided into 60 north-south zones, each covering
a strip 6° wide in longitude. These zones are numbered consecutively beginning with Zone 1,
between 180° and 174° west longitude, and progressing eastward to Zone 60, between 174° and
180° east longitude. Thus, the conterminous 48 States are covered by 10 zones, from Zone 10 on
the west coast through Zone 19 in New England (fig. 1). In each zone, coordinates are measured
north and east in meters. (One meter equals 39.37 inches, or slightly more than 1 yard.) The
northing values are measured continuously from zero at the Equator, in a northerly direction. To
avoid negative numbers for locations south of the Equator, NIMA's cartographers assigned the
Equator an arbitrary false northing value of 10,000,000 meters. A central meridian through the
middle of each 6° zone is assigned an easting value of 500,000 meters. Grid values to the west of
this central meridian are less than 500,000; to the east, more than 500,000.
Virtually all NIMA-produced topographic maps and many aeronautical charts show the UTM
grid lines.

59
Projecting GIS data into the coordinate system of your choice
ArcGIS does project data on the fly. If you are just using data for visualization purposes like map
making you do not necessarily need to re-project the data. If you are using your data in geo-
processing scenarios or to digitize, you should make sure that your vector based data is in the
same projection.
Re-projecting raster data is very processor intensive and might take considerable time.
1. Click the Search window button in the standard toolbar.
2. In the search window click tools
3. Enter projection in the search field.
4. Click projections and transformations.
5. Click Feature.
6. Click Project (data management).
7. Set the following parameters for the Project window:
- Input dataset:
C:reu_2011GIS_datausaNative_american_land_states.shp
- Output dataset:
C:reu_2011studentproject.gdbreservations_projected
8. For the output coordinate system click the projection button
9. In the spatial reference window click select.
10.Choose projected coordinate system / state plane / NAD 1983 (US Feet)
11.Select a state plane zone for your area of interest.

60
12. Click Add.
13. Click OK to close the Spatial Reference Properties window.
14.Click OK to run the projection tool
15.When the re-projection process is done use your knowledge from the
earlier exercise to switch the data frame projection to that of the new
feature class.
In some cases the projection process will involve a datum (geographic) transformation.
This will be indicated in the Project window with a green dot in front of the Geographic
Transformation field. The tool will give you a list of appropriate options for the datum
conversion.
The two most often used transformations in the USA are:
And

61
3.4 Converting xy data from excel tables to a feature class
Your project might require you to import GPS point data into your Geo-database and your maps.
We strongly recommend that you save the GPS coordinates as waypoints (or features) on your
GPS units and import them with programs like DNR-Garmin (if you work with Garmin units),
Pathfinder office (for Trimble units), or ArcPad. The process is covered by chapter 3 of this
document.
In some cases where it is not avoidable you might have to process GPS coordinates which are
given to you in a spread-sheet (or table).
You will now import an (Microsoft excel) spreadsheet into ArcMap and display their x/y
coordinate columns in the map as points.
1. Open C:reu_2011GIS_datatutorialkansasKS_features.xlsx in Microsoft
Excel.
The table contains data for all Named geographic features in Kansas. Part of the data is the
location of the feature. The Location information in this table is given in two forms. The fields
Primary_lat_DMS and Prim_long_DMS show the locations in a degrees-minutes-seconds
format, while the fields Prim_lat_dec and Prim_long_DEC show the same data in decimal
degrees. ArcMap can’t process degrees-minutes-seconds data, so the decimal degrees data is here
the only choice. If you are getting data from the field in a table like this make sure you know in
what coordinate system it was recorded.
2. Close Microsoft Excel
3. Open the map document C:reu_2011GIS_dataIntroduction to ArcMap.mxd
4. Click add data .
5. Navigate to C:reu_2011GIS_datatutorialkansasKS_Features.xlsx and
add the table.
When you add a standalone table to ArcMap the TOC will switch to the list by source view,
since standalone tables do not show in the ―
list by drawing Order‖ view.

62
6. Right click the KS_Features table in the TOC.
7. Click display XY Data.
8. In the Display XY Data window choose PRIM_LONG_DEC for the x field.
9. Choose PRIM_LAT_DEC for the Y field.
10.Click Edit for the Coordinate System.
11. In the XY Coordinate System window click select
12.Navigate to and choose Geographic Coordinate SystemsWorldWGS
1984.prj
13.Click Add to close the Browse for Coordinate System window.
14.Click OK to close the Spatial Reference window.
15.Click OK to close the XY Data window and run the process.

63
16.A message will show that the table does not have Object-ID field  Click
OK.
After processing the map should now show the locations from the table as points.
So far the new layer exists just as an event layer in the map document. In the next steps you will
make this layer permanent by converting it to a feature class in your geo-database.
17.Right click the KS_features event layer in the TOC.
18.From the drop down list click DATA  Export Data.
19.For the output feature class navigate to the test.gdb you created earlier in
the exercise.
20.Name the feature class Kansas_geo_features.

64
21.Click Save.
22.Click OK.
23.When asked if you want to add the exported data as a map layer click yes.
The TOC in the list by source view should now show the Kansas_geo_features.
24. Close the map document.
4. Editing data
In some cases you might want to make an old map fit some of the GIS data you are working with
(geo-referencing) or you might want to create (digitize) a point, line or polygon layer from
features you see on an old map or aerial photo. The following exercise will introduce you to both
activities.
4.1 Georeference Raster data
Geo-referencing old maps or aerial-photos to existing data is common in many GIS processes.
1. Open the C:reu_2011map_documentsLandcover_change.mxd
2. Add C:reu_2011GIS_datatutorialkansas_dataaerial_imagerydg1966.jpg
3. When asked if you would like to build pyramids click Yes.
From ArcGIS help:
Pyramids are used to improve performance. They are a down-sampled version of the original
raster dataset and can contain many down-sampled layers. Each successive layer of the pyramid

65
is down-sampled at a scale of 2:1. Below is an example of two levels of pyramids created for a
raster dataset:
4. Add C:reu_2011GIS_datatutorialkansas_dataaerial_imagery
ortho_2008.jp2
5. Zoom to the bookmark Lawrence.
6. Click Customize from the menu bar.
7. Click toolbars and switch on the geo-referencing toolbar.
8. Make sure the dg1966.jpg is on top of the 2008 ortho-photo in the TOC.
9. In the geo-referencing toolbar make sure the layer is set to the 1966 image.
10.Switch of the USA Base map.
11. Move your mouse over the Lawrence area in the map and observe the
coordinates for the area in the lower right corner of your screen
12.Zoom to the extent of the dg1966 image.
13.Move your mouse to the upper left corner of the image and observe the
coordinates for the area in the lower right hand corner of your screen.

66
The 1966 image does not have any coordinates assigned to it (it is not geo-referenced yet) . By
default the upper left corner of any unreferenced image loaded into ArcMap is set to 0,0. The
following process will create a world file for the image which will reference the upper left corner
to coordinate somewhere around Lawrence Kansas.
(From ARCGIS 10 Help)
14.Click Georeferencing.
15.Click fit to display
The 1966 image should now be roughly moved over the 2008 image and into the coordinate
space.
16. Zoom in to Interstate 70 which is shown in the northern part of both
images.
17.Search for a feature you can identify on both images (switching on and off
the 1966 image).
18.With the 1966 image visible click the add control points tool from the
geo-referencing toolbar.
19.Click the feature (you identified to be visible in both images) on the 1966
image first.

67
20.Switch of the 1966 image.
21.Click (and set the second of the control point pair) on the 2008 image.
This image shows a set of control points set at the intersection I70 and Hwy 59 on the east side
of the Kansas River (use the USA Base map if you want to find the same intersection).
The 1966 will adjust a little better to the map with each control point you set.
22.Repeat steps 21-25 for at least 4 more points which should be evenly
spread on the 1966 image.
If you set all control points in one line (along I 70 for example) you will get the following
message.
Once you click ok you might see an unwanted warp in the 1966 image.
Regardless if you get this message or you distributed your control points well throughout the
image and do not get the above message, the following steps let you adjust your already set
control points.
23.Click the view link table button in the Geo-referencing toolbar.
24.If the last of the control points you set was creating the above error
message, Highlight the last entry in the control points table and hit the
delete button .

68
The Table shows the X/Y source coordinates and the x/y map coordinates for each point. The
residual is the amount by which each source point is adjusted to reach the Map point. Low
Residuals show that the adjustment is going well. High Residuals show possible problems. By
deleting control points with higher residuals the total RMS error might be adjusted.
The transformation can be set to an affine, second order polynomial or third order polynomial.
The higher order the transformation the more well distributed control points have to be set.
25.Set at least 10 control points.
26.Once you are satisfied with the results click Georeferencing.

69
27.Click update Georeferencing.
A dg1966.jgw world file is now written to the folder where the image resides. This world file
will reference the image to the coordinate system.
28. Leave the map document open
4.2 Digitizing
You will now digitize the land-cover in 1966 and 2008 around Lawrence.
The land cover will be digitized as polygon feature classes. For training purposes you will also
create a point and polyline feature class for features on the Haskell campus.
Create feature classes
First you will create the feature classes needed for the exercise.
1. In the ArcCatalog window of the map navigate to the project.gdb under
c:reu_2011student folder.
2. Click new  feature class
3. In the new feature class window type landcover_1966 for the name.
4. Make sure the feature type is set to polygon features.
5. Click the next button.

70
6. In the choose coordinate system window click import.
7. Navigate to
C:reu_2011GIS_datatutorialkansas_dataaerial_imageryortho_2008.jp2
8. Click Add

76
Create coded value domain in geo-database for land-cover classes
When digitizing in for your project you should define what you are digitizing first. In this case it
is advisable to create a list of land cover classes to be digitized and save them as a coded value
feature domain in the geo-database that can be used for the 1966 and the 2008 land cover feature
class. The coded value domain will limit the possible values that can be entered in the land cover
field to the predefined set of values. The classes you are going to digitize are: Forest, Water,
Agriculture, Build-up (roads, neighborhoods, industrial areas, campuses).
1. In the ArcCatalog window of the map navigate to the project.gdb under
c:reu_2011student folder.
2. Right click the project.gdb.
3. Click the domain tab.
4. Enter land cover under domain name

change the template for the landcover_1966 layer to the new symbology.

80
Digitize land cover changes from 1966 to 2008 around Lawrence
1. Add C:reu_2011GIS_datatutorialkansas_datadig_sections.shp.
2. Zoom to the dig_sections layer.
3. Label the sections with their ID numbers (feature properties  labels)
4. Split up into four groups, each group should work on one of the four
sections.
This exercise will use section 1 for an example.
5. Use a definition query or selection  create layer from selected features
process to just show the section you are working on.
6. Zoom to the northwest corner of your section.
7. Select the landcover class you want to use for the NW corner of your
section from the landcover_1966 template in the create features window.
8. Use the automatic snapping and the feature and the half transparent

smaller forested area to the east and the outline of the section to the north and west.

81
13.Choose the next land cover class to be digitized from the template.
14.For all the following polygons use the auto complete polygon tool from the
construction tools section of the create features window.
The auto complete Polygon tool makes sure that you don’t create any overlaps or gaps between
the polygons. The auto Complete Polygon is the most used construction tool when digitizing
land-cover, land parcels or vegetation types.
15.Start digitizing by snapping to a corner point of an existing polygon
16.Digitize around the next land-cover area.
17.Snap again to a corner point of an existing polygon.
18.Finish the sketch with a double click

82
19.Use the four template options for the 1966 land cover layer and the
autocomplete polygons to cover the area of your section with a continuous
land-cover layer ( don‟tforget to pick the right landcover class first and
then the auto complete polygon tool).
Below is a screen shot of a rough classification for section 1.
20. When You are done digitizing the land cover for your section save your
edits.

83
Digitize the 2008 land cover for your section.
4.3 Edit the attribute table
To calculate the area for each land-cover class for your section in acres you will have to create a
new field in the table and calculate it to acres.
1. If your edit session is still open save your changes and close the edit
session.
2. Open the attribute table for the 1966 land cover layer.
The Shape_area field records the area for each polygon in the units defined in the Projection
information; it is also automatically updated whenever the polygon shape is updated. The units
recorded here are square meters (the layer is in a UTM projection).
3. Click the table options button in the upper left corner of the table
window.
4. Click add field.
5. Name the field acres
6. Set the type to float.
7. Click OK.
8. Right Click the header of the new acres field.
9. Click Field calculator.
The conversion factor from square meters to acres is 4046.86.

84
Use the Summary Statistics tool to compare the acres by land-cover
class of the year 1966 and 2008 for your section.
10.In the field calculator double click shape_area
11.Type / 4046.85642 (see image below)
12.Click OK.
13.Repeat steps 2-12 for the 2008 land cover class.

85
5 Geo-processing tools
Geo-Processing tools let you extract data from base maps for your study areas, buffer geographic
features to see which other features are within a certain distance, create overlays to combine their
attribute information and many more processes which can only be done with a GIS.
In this Chapter you will use several different geo-processing tools in a real world scenario.
This is the situation:
The Confederate tribes of Grand Ronde are working to increase the habitat of the western Pond
Turtle (Clemmys marmorata). The Tribal Biologists asked you to produce a map of possible
turtle habitats on private land in the south Yamhill watershed.
Turtle habitat:
- Should be with in a distance of 300 feet to rivers and streams (so it does not isolate).
- Should have at least 2 or more of the following characteristics: wetland, Riparian
vegetation, hydric soils.
All the data you need is already loaded into a Map document.
1. Open the C:reu_2011map_documentsgeoprocessing.mxd in ARCMAP.
The map shows streams and wetlands in the South-Yamhill area.
5.1 Raster to vector conversion
There are still some pre-processing steps for you to do before you can get started with the
analysis.
Make the ―
Vegetation (raster data) from GAP Analysis‖ layer visible and explore its symbology.
This layer is a result of an Image processing and analysis procedure (you will do a similar
procedure in chapter 8 of this tutorial) based on satellite image data. The layer consists of raster
cells (with a 30m resolution) each of the cells are classified with a different color representing
different vegetation types. Spatial analysis like the overlays you will be doing can only be done
on either all vector layers or all raster layers. Therefor the vegetation layer needs to be converted
to a vector (polygon) layer. The conversion from raster to polygon makes only sense on
classified rasters, it does not make sense to convert raw imagery like aerial photos or satellite
images.
2. In the standard toolbar click the search window button .

86
Another option is to use the toolbox and browse for the ―
raster to polygon‖ tool.
3. Click on tools.
4. Enter “raster to polygon” in the search field
5. From the results click the raster to polygon tool link.
6. With the Conversion tool open close the search window.
7. In the Raster to polygon window use the drop down for the Input Raster
and choose Vegetation (raster data) from GAP Analysis.
8. For the field choose OR_names
9. For the output polygon features browse to
C:reu_2011GIS_datatutorialoregon_dataoregon.gdb
10.Type veg_poly for the name.

87
11.Click OK
While the conversion is running in the background (indicated by in the
lower section of your screen) you can go ahead to the next topic. Once the veg_poly layer is
added to the map turn it to non-visible and remove the Vegetation (raster data) from GAP
Analysis from the map document.
5.2 Buffer
There is two ways to do a buffer analysis in ARCGIS. The first one option lets you create the
buffer as a polygon feature class, which can then be used for further geo-processing like clip
functions. The second lets you select Target layer(s) features which are in a certain distance
around source layer features.
You will use both options but ultimately use the second option for this project.
Create a buffer polygon feature class
12.In ArcMap click Geo-processing in the menu bar
All Geoprocessing tools are also available through ArcToolbox or the search window .

88
13.From the geo-processing tools list choose buffer.
14.In the Buffer tool window click show help.
The tool help illustrates how the buffer tool works.
15.Use the drop down arrow for the Input feature to put streams in the input
features field.
16.In the Output Feature Class field navigate to
C:reu_2011GIS_datatutorialoregon_dataoregon.gdb.
17.Enter streams_buffer for the name
18.In the linear unit field enter 300 .
19.Switch the Unit field to feet.
20. Switch the dissolve type to All.
This will create one contiguous polygon rather than one buffer polygon for each stream section.
21.Click OK.
The geo-processing indicator window will be visible during the
processing, after which the new buffer layer will be added to the map document.
As you can see from the screen shot below there are some wetlands which are not covered by the
buffer layer.

89
22. Remove the Stream buffer from the map.
Use Select by location buffer function
23.Click selection in the menu bar.
24.Click select by location.
Reading through the text in the selection tool window will give you a better understanding of
what is going to be selected.
25.In the Select by location tool window for the target layers(s) check
veg_poly, wetlands, soilmu_a_or679 and soilmu_a_or053.
26.Source layer: Streams
27.Spatial selection method: Target layer(s) features are within a distance of
the source layer feature.
28.Check the apply a search distance
29.Enter 300 feet for the search distance
30.Click OK

90
Features within a distance of 300 feet around streams are now selected in the veg_poly,
wetlands, soilmu_a_or679 and soilmu_a_or053 layers.
31.In the TOC select the view by selection view by clicking .

91
You will now create layers from these selected features.
32.Switch the TOC back the view by drawing order .
33.Right Click the veg_poly layer in the TOC.
34.Click selection
35.Click Create layer from selected features.
36.Rename the new layer to “veg_poly in buffer”
37.Remove veg_poly from the map.
38. Repeat steps 33-37 for the other 3 layers with selected features:
Soilmu_a_or 53  Soil_53 in buffer
Soilmu_a_or679  soil_679 in buffer
Wetlands  wetlands in buffer
Use Select by attribute to create further filter
Next you will need to extract the riparian vegetation types from the veg_poly layer
1. Right click the “Veg_poly in buffer” layer in the Toc
2. Click Open Attribute Table.
3. In the attribute table click the drop down next to the table options button

92
4. Select by Attributes
You will now create a query which will select a list of vegetation types (riparian) from the layer.
5. In the Select by Attributes window double click the “OR_names” field to
start the query.
6. Click the “get Unique values” button
7. Type “in (“ after the “OR_Names” entry in the query text box.
8. Enter the following vegetation types by double clicking them in the list
and enter a comma between them;
'Freshwater Aquatic Bed',
'Water',
'Westside Forested Swamp or Wetland',
'Westside Lowland Riparian',
'Westside Montane Riparian',
'Westside Valley Wet Prairie‟
9. Close the list with a ).
Your query should now read like this:
"OR_NAMES" in ( 'Freshwater Aquatic Bed', 'Water', 'Westside Forested Swamp
or Wetland', 'Westside Lowland Riparian', 'Westside Montane Riparian', 'Westside
Valley Wet Prairie')
10. Click verify to see if you entered everything correct.
11.Click Apply

93
9135 features should now be selected
12.Close the table.
13.Right click the “Veg_poly in buffer” layer in the Toc.
14.Click data  export data

10
11

94
16.Click Yes to add the exported data as layer to the map.
17. Remove the “veg_poly in buffer” layer from the map.
5.3 Table Join
The next step in the Analysis is to find out which of the soils in the buffer are actually hydric
soils. The attribute tables of the soils layer do not contain that information but a key field
―MUKE
Y‖ which can be joined to soil data tables that contain hydric information.
Each of the two soil layers has a soil database assigned to it.
1. Add data:
C:reu_2011GIS_datatutorialoregon_datasoil_or053soildb_OR_2003.mdb
component table
2. Right click “soil_053 in buffer” in the TOC
3. Click Joins and Relates  Join

95
4. In the Join window choose “Join attributes from a table” to be joined to
this layer.
5. For Field under 1. choose MUKEY
6. For table und 2. choose component.
7. For field from component to base the join on (6.) choose mukey.
8. For Join Options: keep all records.
9. Click OK
10.Open the attribute table of the soil_053 in buffer layer
The attribute table should now be extended with the data from the component table.

96
11. Open the select by attributes window (upper left corner).
12.Find and double click the component.hydricrating field from the field list.
13. Click the = button
14.Click the “get Unique values” button
15.Double click „Yes‟ f
rom the values list.
The text in the query text field should now read component.hydricrating = 'Yes'.
16.Click apply
322 records should now be selected.
17.With the hydric soils selected right click the soil_053 in buffer layer in the
TOC.
18.Click Joins and Relates  Remove join  component.
This step is done to limit the size of the attribute table to be exported.

97
19.Using your knowledge acquired on page 61-62 save the selected features
as hydric_soils_053 in the Oregon.gdb.
20.Remove the soil_053 in buffer and the component table from the map.
21.Repeat Steps 1-20 for the soil_679 in buffer layer using the soil-database
under C:reu_2011GIS_datatutorialoregon_datasoil_or679.
The TOC in your map should now look like this
5.4 Merge
Now you will merge the two hydric soil layers into one to make further analysis steps simpler.
5. Open the search window
6. Search for merge under tools
7. Open the merge (data management) tool.
8. Add the hydric_soils_0679 and hydric_soils_53 for the Input Datasets.
9. For output Dataset: C:reu_2011testtest.gdbhydric_soils
10.Click OK

98
After the process the hydric_soils layer will be added to the map.
11.Remove hydric_soils_0679 and hydric_soils_53 from the map.
5.5 Union
Now you will create an overlay of hydric soils, wetlands and riparian vegetation areas.
The idea is to create a ranking of 1-3 1 for areas which are covered with only one of the above
mentioned layers, 2 where two of the above mentioned layers overlay and 3 where all of the
layers overlay.
To make this ranking easier you will create a new column in each of the 3 layer’s attribute table
with the all values set to 1.
1. Open the Attribute table for the Hydric_soils layer.
2. From the table options menu choose Add field.
3. Name the new field hydric soils
4. Make sure the type is set to short integer.

99
Use the help for the intersect and the union geo-processing tool to decide
which one to use for the overlay.
5. Click Ok to create the field
6. Right click the header of the new field.
7. From the drop down choose Field calculator.
8. In the field calculator set the hydricsoils = 1
9. Click ok.
10.Once you verified that the new field is set to 1, close the table.
11.Repeat steps 1-10 for layers riparian_veg_in_buffer and wetlands in buffer
name the new fields riparian and wetland respectively.

100
12. Find and run the union tool.
You can find the tool under geo-processing in the menu bar, in Arc-Toolbox under
Analysis/Overlay and through the search window.
13. Input features: hydric_soils and riparian_veg_in_buffer
If you are running an ArcInfo version of ArcGIS you could run the UNION on more than 2
layers.
14.Output feature class:
C:reu_2011GIS_datatutorialoregon_dataoregon.gdbhydric_riparian
15.Make sure the Join Attributes is set to ALL
16.Run the Union tool again with
Input: hydric_riparian, wetlands in buffer
Output: C:reu_2011GIS_datatutorialoregon_dataoregon.gdb
turtle_habitat.
17.Once the turtle habitat layer is created you can remove the hydric_soils,
riparian_veg_in_buffer and the wetlands in buffer layers from the map.
Now you will have to classify turtle habitat areas by ranking schema discussed above.
18.Open the Attribute table for turtle_habitat layer.
19.Add a new field
Name: Ranking

101
Type: Short Integer
20.Open the field calculator for the new Ranking field.
21.Use the fields list box and the + operator button to create the following
formula:
[hydricsoils] + [riparian] + [wetland]
22.Click OK to run the tool.
23.Use the definition query from the layers Properties window to just show
only the polygons with a ranking value of 3.

102
The map should now show the habitat polygons with a highest ranking value.
After you created the turtle habitat map, the tribal BioloGISts field surveyed (with GPS) the
habitat areas and brought back GPS locations of turtle sightings.
Your job is it now to find out on which parcels of land (taxlots) these points fall and supply the
BioloGISts with a tax lot number for each point.
5.6 Clip
Use this tool to cut out a piece of one feature class using one or more of the features in another
feature class as a "cookie cutter". This is particularly useful for creating a new feature class—
also referred to as study area or area of interest (AOI)—that contains a geographic subset of the
features in another, larger feature class. The AOI here are two watersheds around Grand Ronde.
The data that needs to be clipped is the Tax lot data for Yamhill and Polk county.
12.Add data C:reu_2011GIS_datatutorialoregon_dataoregon.gdbtaxlots
and watersheds.
13.Open the clip tool from the Geoprocessing menu on the menu bar.
14.Run the clip tool with the following parameters:
Input Features: taxlots
Clip Features: watersheds
Output Feature Class: C:reu_2011testtest.gdbtaxlots_clipped

103
15.Click ok to run the tool
16.Once the taxlots_clipped layer is added to the map remove the watersheds
and the taxlots layer.
5.7 Spatial join
With the tax-lot data clipped you can now do the spatial join to assign the tax-lot ids to the GPS
point layer. The GPS data is already converted (see conversion methods in the GPS section of
this class) to a feature class.
1. Add data C:reu_2011GIS_datatutorialoregon_dataoregon.gdb
turtle_GPS_points
2. Right click the turtle_GPS_points layer in the TOC
3. Choose Joins and Relates  Join
4. Set the following parameters in the join tool:
What do you want to join to this layer:
Join data from another layer based on spatial location
1.: taxlots_clip

104
1) Do all the GPS points fall in a 3 ranking habitat polygon?
2) What percentage of each of the identified taxlots are covered by turtle
habitat (all rankings)?
2.: it falls inside
3. Output layer:
C:reu_2011GIS_datatutorialoregon_dataoregon.gdb
gps_points_taxlotinfo
5. Click OK to run the tool.
17.Once the gps_points_taxlotinfo layer is added open its attribute table.
All the GPS points should have tax lot information assigned to them now.

105
6. Image processing / remote sensing
The following section will introduce you to digital remote sensing especially to the processing of
multispectral satellite data.
This tutorial is just an introduction to the wide field of remote sensing (RS). You should be
aware that there are advanced RS data sources like Light Detection And Ranging ( LIDAR)
(http://www.oregongeology.org/sub/projects/olc/olc.ppt)
and advanced RS processes like Object-Based-Image-Analysis (OBIA)
(http://www.GIS.unbc.ca/courses/geog499/projects/2005/fremmers/index.htm)
which cannot be covered here.

Downloading Land-Sat Imagery from USGS GLOVIS
http://youtu.be/o401hk-09RE

106
6.2 Working with multi spectral image data in ARCGIS
Although there is a multitude of multispectral image data available today as discussed in the
Sources above, you will be working here with data taken by the Thematic Mapper (TM) mounted
on NASA’s Landsat satellite.
TM data is widely used since the mid 1980’s to map Vegetation health and land use change (on a
regional level) worldwide.
TM data (from 1985 to now) is available through the USGS Global Visualization Viewer
(http://glovis.usgs.gov/).
After you download the data you will need to unzip it before you can use it in ARCGIS.
The files unzip into seven .tif files and two metadata files.
Each TIF contains one spectral band of data from the TM instrument.
Use the Spectral Characteristics Viewer (http:/landsat.usgs.gov/tools_spectralViewer.php) to see
which TM bands to use best for your project.
Loading TM data into ArcMap
1. Open C:reu_2011map_documentsTM_lawrence.mxd in ArcMap.
The map shows the area around Lawrence Kansas
2. Add the 7 L5027033_03320100823 .tif files from
C:reu_2011GIS_datatutorialtm_kansas to the map as data.
3. Switch of the USA base map layer
4. Click windows in the menu bar.

107
5. Click Image analysis.
The Image Analysis tool is new in ARCGIS 10 and not available in earlier versions of the
software.
Create color composites
Color composites are made by assigning the three primary colors to three bands of
the TM sensor.
True color composite:
Red band displayed as red, green as green, blue as blue.
This is how we see the world.
False color composites:
These images are not color photographs, they are"false color" images (green fields won't
necessarily look green in the image).
One common way that primary colors are assigned to bands can be easily remembered using the
mnemonic -
RGB = NRG (Red, Green, Blue = Near Infrared, Red, Green, or "energy")
Red = Near IR (TM+ band 4)
Green = Red (TM+ band 3)
Blue = Green (TM+ band 2)
(http://landsat.gsfc.nasa.gov/education/compositor/pdfs/Landsat_7_Compositor.pdf)
You will now create a composite of all 7 bands of the TM data. You can then choose which
bands you want to display with what gun (Red, Green, Blue).
1. In the Image Analysis window highlight all 7 .tif files
2. Under processing click the Composite Bands button .

108
3. In the TOC open the Properties window for the newly created composite.
4. In the general tab rename the layer to TM Composite Lawrence 08_23_2010
(4,3,2).
5. In the Symbology tab set:
Red channel = Band 4
Green channel = Band 3
Blue channel = Band 2
Display Background = 0 0 0 as transparent
Stretch Type = Standard Deviation (2)
Statistics = From currently displayed extent
6. Click ok to close the layer properties.
7. Save the Composite as a layer file to C:reu_2011student folder
8. Remove the 7 original .tif files from the map.

9. Follow steps 1-8 to create a false color composite (4,3,2) for the
LT5027033008422850 TM layers (acquisition date: 08.15.1984) from the
tm_kansas folder.
10.Change the band combination of the two composites to true color (3,2,1) to
see the difference between an false color composite and a true color
composite.
Create a Normalized Difference Vegetation Index (NDVI) image in ArcMap
The principle behind NDVI is that Band 3 is in the red-light region of the electromagnetic
spectrum where chlorophyll causes considerable absorption of incoming sunlight, whereas Band
4 is in the near-infrared region of the spectrum where a plant's spongy mesophyll leaf structure

creates considerable reflectance (Tucker 1979, Jackson et al.1983, Tucker et al. 1991). As a
result, vigorously growing healthy vegetation has low red-light reflectance and high near-
infrared reflectance, and hence, high NDVI values. NDVI values near zero and decreasing
negative values indicate non-vegetated features. (USGS – what is NDVI).

1. In the Image Analysis window highlight the Lawrence 08_23_2010 (4,3,2)
composite.
Before running the NDVI you have to make sure that the right bands of the composite are used in
the function.
2. In the Image Analysis window click the options button
3. Click the NDVI tab and make sure that band 3 of the composite is used for
the red band and band 4 as infrared.

111
4. Close the options window.
5. With the composite still highlighted click the NDVI button .
6. With the NDVI created zoom into the area around Lawrence.
7. Use the Swipe and flicker tools to compare the NDVI with the false
color infrared composite.

112
8. Repeat steps 5-6 for the 1984 composite.
9. Compare the NDVI layers from 1984 AND 2010
10.Keep the map document open.
Create a vegetation layer from NDVI image.
One way to quantify vegetation coverage from a TM scene is to use the NDVI image and apply a
threshold value above which pixels are classified as vegetation.
In this exercise you will again create a NDVI, but this time from an aerial image from the
NATIONAL AGRICULTURE IMAGERY PROGRAM (NAIP).
The default spectral resolution for NAIP data is natural color (Red, Green and Blue, or RGB) but
beginning in 2007, some states have been delivered with four bands of data: RGB and Near
Infrared.
The order of bands in the NAIP data is 1=red,2=green,3=blue,4=infrared. The NDVI will
therefore have to be run on bands 1 and 4.
1. Add the C:reu_2011GIS_datatutorialkansas_dataaerial_imagery
ortho_2008.jp2.

113
2. Use the layer properties symbology tab to display the image as false color
composite (4,3,2).
3. Open the image analysis window (windows in menu bar).
4. Highlight the ortho_2008.jp2
5. Click the options button .
6. Click the NDVI tab
7. In the NDVI tab switch the red band to 1 and the infrared band to 4.
8. Click OK.
9. Use the NDVI tool on the 2008 NAIP image.
10.Zoom in to the bookmark Lawrence.
11.Open the layer properties of the new NDVI layer.
12.Click the Functions tab.
The function tab shows you that the NDVI layer is put together on the fly from the
ortho_2008.jp2 layer. In order for us to reclass the NDVI in to a layer showing just areas with
green vegetation we will have to save an image file with the values of the NDVI function layer.
13.Right click the Colormap Function.
14.Click remove.
15.Close the Layer properties window.
16.Right click the NDVI layer in the TOC.
17.Choose Data  Export data.
18.In the export data window set the following parameters:
Extent: Data frame (current)
Cell Size: 2 / 2
Location: C:reu_2011student

114
Name: NDVI_Lawrence
Format: TIFF
Compression: LZW
19.If the Uncompressed Size of the file is much larger then shown above you
are not zoomed in to the Lawrence bookmarked extent.
20.Click Save.
21.When asked if you want to add the exported dataset to the map click yes.
22.Open the layer properties for the NDVI_lawrence layer.
23.Rename the layer “Vegetation”
24.In the display tab set the transparency to 50%
25.In the Symbology set Show: Classified
26.Set Classes to 1.
27.Click Classify.
28.In the Classification window click Exclusion.

115
29.Exclude Values: 1-108
30.Click ok.
31.Click ok to close the classification window.
32.Click apply in the Layer Properties.
Explore the map to see if the new vegetation layer covers the areas with green vegetation as seen
on the ortho-photo.
Adjust the exclusion value (as discussed in step 27-29) if needed.

116
By now you should have access to some multispectral remote sensing data for your Study
area.
1) Load the data in ArcMap into a new map and create infrared composites.
2) Create NDVI’s with your data (or you could look up and run a Snow and Ice Index).
6.3 Digital image classifications in ArcGIS
Image classification and analysis operations are used to digitally identify and classify
pixels in the data. Classification is usually performed on multi-channel data sets (A) and this
process assigns each pixel in an image to a particular class or theme (B) based on statistical
characteristics of the pixel brightness values. There are a variety of approaches taken to perform
