Osm Training Ht10 Hot English Version
1. Intro to OSM
Open Street Map is a web project to create a free and open map of the entire
world, built entirely from volunteers surveying with GPS, digitizing aerial
imagery, and collecting and liberating existing public sources of geographic
data.
The goals of this training are to:
1 – Familiarize participants with the basics concepts of OSM
2 – Give introduction to field data collection/ground-truthing using GPS,
Walking Papers and Questionnaires
3 – Provide instruction on how to edit data using JOSM
4 – Give a basic understanding of the OSM data model
5 – Provide generic instruction on how to use OSM data in GIS map production
(ESRI & QGIS) – GISers only-
2. GPS and Walking Papers
Combined, GPS and Walking Papers
can be used for rapid surveying and
ground truthing.
Walking Papers allow users to print
out small sections of the OSM map. In
the field, these paper maps can be
used to draw new features, annotate
existing data, and take notes that will
help with the import of GPS data.
Icons in each of the corners and a
unique code for each Walking Paper
let users scan the paper and upload to
OSM so the notes can be viewed in an
editing environment.

Very basic GPS devices will work.
We're only looking at collecting points
and tracks.

4. JOSM and Potlach
JOSM and Potlach are the two main
editors used for creating and
modifying OSM data.
Potlach is a simple web interface,
accessible to users on the
OpenStreetMap website.
JOSM is a more advanced tool, is a
Java application so doesn't require
consistent internet access and can run
on any operating system.
6. Surveying plan/ tactics
= Objective =
•Aim
•Features to collect
•Area of Interest:
= Support Docs =
* Data structure
** data model (UNSDIT, DTM)
** OSM MapFeatures
** Humanitarian Data Model bridging between data models and OSM Map features
* Questionnaires
* Presets for data editing
* tech: OSM platform
= Organisation =
* Survey zones
* Teams (2/3)
* Combined use of surveying tools and techniques:
** GPS: navigation and points + tracks marking.
** Walking papers: navigation + annotation (geometry + attributes)
** Questionnaires
7. GPS Babel
To get data off your GPS and into a format usable by JOSM, we use a free
software called GPS Babel. Connect your GPS device to your computer using
the USB cable, select Device and Garmin serial/USB protocol as an input format.
Then choose GPX/XML as your output format, name your file, and hit “let's go.”
GPS Babel can also convert GPS data KML, CSV and other formats.
8. Starting JOSM and Adding Data
Starting JOSM with additional memory (Optional):
Command prompt for JOSM installed on the desktop:
C:>WindowsSystem32java.exe -jar -Xmx512M "C:UsersuserDesktopjosm-tested.jar"
Adding Your GPX data:
In JOSM, go to “File->Open” and select the GPX file you just created.
Adding Existing OSM data:
You'll want to start with the data already exists in OSM and have your editing strategy be
based on adding new features or modifying those that are already there.
To download data directly from the server, zoom to the bounds of your GPS data in the
main browser, then go to “File->Download from OSM.” Your extents will be pre-
highlighted in pink. Click download, making sure the “Download as new layer” box is
checked.
If you already have OSM data at hand that you want to use, you can open it as you did
with the GPX data already and it will appear as a new layer.
9. Walking Papers
When you've collected your Walking Papers data, you need to scan it and save the
resulting image on your computer. Go to: http://walking-papers.org/upload.php and
follow the instructions there. Once uploaded, the site will give you a unique URL for
your scan.
Go to JOSM, and select Walking Papers from the menu, choose “Scanned Map,”
enter the URL of your scan and press “OK.”
You will now see your scan alongside the existing OSM data and your GPS tracks.
11. Relevant tags/features
OSM attribute data is stored in key:value pairs. The tagging system is completely
flexible, new keys and possible values can be added ad hoc. But in order to ensure
compatibility between data, it's best practice to use existing tags where possible.
The full list of recommended tags can be found on the OSM wiki at:
http://wiki.openstreetmap.org/wiki/Map_Features
Details on the Humanitarian Data Model and the JOSM presets we've built to
accompany it can be found at:
http://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Tags/Humanitarian_Data_Model
For the purposes of today's session, here are some suggested tags to use when adding
your data:
Key Possible Values
Area yes
Building container, tent, hangar, tent, yes
Amenity bathroom, parking lot, fountain, school, health clinic
Highway pedestrian, service, secondary
Surface gravel, dirt, concrete, paved, unpaved
Source Walking Papers/GPS
12. Using OSM resources in ArcGIS and QGIS
This module meant to GIS practitioners will cover the following:
Loading OSM data (shp, wfs, postres-postgis table, wms)
Exploring OSM data
Editing OSM data
Visualizing OSM data
Rendering OSM data (basic & more advanced cartography)
13. Humanitarian OpenStreetMap Team (HOT)
