2.  A geographic information system (GIS) integrates
hardware, software, and data for capturing,
managing, geographically analyzing, and displaying all
forms of referenced information.
 Geographic information systems (GIS) is also
known as Geospatial information systems are
computer software and hardware systems that enable
users to capture, store, analyse and manage
spatialially referenced data.

3.  GIS allows us to view, understand, question,
interpret, and visualize data in many ways that
reveal relationships, patterns, and trends in
the form of maps, globes, reports, and charts.
 GIS technology can be integrated into any
enterprise information system framework.

4. • GIS is a System of computer software,
hardware and data, and personnel to help
manipulate, analyze and present
information that is tied to a spatial
location –
• spatial location – usually a geographic location
• information – visualization of analysis of data
• system – linking software, hardware, data
• personnel – a thinking explorer who is key to
the power of GIS

5. What is Not GIS ? ?
What is Not GIS
• GPS – Global Positioning System
• A static map – paper or digital
–Maps are often a “product” of a GIS
–A way to visualize the analysis
• A software package

6. Spatial Data
Spatial Data
• Estimates are that 80% of all data has a
spatial component.
–Data from most sciences can be
analyzed “spatially”.

7. What is GIS ?
• A method to
visualize, manipulate,
analyze, and display
spatial data.
• “Smart Maps”
linking a database to
the map.

8. Some Ways GIS is Used
• Emergency Services – Fire & Police .
• Environmental – Monitoring & Modeling.
• Business – Site Location, Delivery Systems.
• Industry – Transportation, Communication, Mining,
Pipelines, Healthcare.
• Government – Local, State, Federal, Military.
• Education – Research, Teaching Tool, Administration.
Wherever Spatial Data Analysis
is Needed

9. SOFTWARE PROGRAMS FOR GIS
•MapWindow GIS •gvSIG
•Quantum GIS •Manifold
•DIVA – GIS
•uDig GIS
•AccuGlobe 2007
•SAGA

11. • MapWindow GIS is an Open Source GIS (mapping)
application and set of programmable mapping
components. Because it is distributed as an open
source application under the Mozilla Public License
distribution license, MapWindow GIS can be
reprogrammed to perform different or more
specialized tasks.

12. • There are also plug-ins available to expand
compatibility and functionality. MapWindow
GIS is built upon Microsoft.NETtechnology but
is not a multi-platform application and hence
does not run on non-Microsoft operating
systems including UNIX.

14. • Quantum GIS is an open source GIS (mapping)
application which is similar to commercial mapping
packages. Because it is distributed as an opensource
application under the GNU distribution
license, Quantum GIS can be reprogrammed to
perform different or more specialized tasks. There are
also plug-ins available to expand compatibility and
functionality.

15. • It is a multi-platform application and runs on
different operating systems including Mac OS X,
Linux, UNIX, and Windows XP.
• Quantum GIS has a small file size compared to
commercial GIS's and requires less RAM and
processing power; hence it can be used on
older hardware or running simultaneously with
other applications where CPU power may be
limited.

18. • uDig is an open source GIS software program
produced by a community led by Canadian-
based company Refractions Research. It is based
around the Eclipse platform and features full
layered Open Source GIS. It is written in Java and
released under GNU Lesser General Public
License.

19. • uDig has a walkthrough in Flash and also quick
start directions for those who wish to
complete a full version build to write plug-ins
or contribute to the main build.

23. • gvSIG is a multilingual, open source
geographic information system (GIS) that can
handle both vector and raster data. It features
basic editing tools for the creation and
maintenance of vector or raster spatial data
on a variety of file formats, including remote
data sources.

24. • gvSIG is being actively developed in Java by
IVER Tecnologías under the GNU General
Public License (GPL) [1]. Its name is a Spanish
abbreviation that stands for Generalitat
Valenciana. Sistema de Información
Geogràfica.

28. • Manifold System is a geographic information
system (GIS) software package developed by
manifold.net that runs on Microsoft
Windows. The GIS software competes with
ESRI and MapInfo GIS products.

29. • Manifold 7.00 handles both vector and raster
data, includes spatial SQL, a built-in Internet
Map Server (IMS), and other general GIS
features. Manifold System has a vibrant user
community with a mailing list and online
forums.
