GIS is a computer system for capturing, storing, analyzing and displaying geographic information. It allows users to integrate digital maps, aerial photos, satellite images and GPS data. The presentation introduces GIS components, data models, how GIS works in a 5 step process, and examples of GIS applications for 3D city modeling, traffic simulation, watershed delineation and political analysis. It also discusses the ArcGIS software suite, including ArcMap for mapping, ArcCatalog for data management and ArcToolbox for geoprocessing tools.

Introduction to Geographic Information System(GIS)
DAY 1

2. What is GIS???

3. Software

4. GIS
(Geographic Information System)
 A computer-based system that can be used to
capture, store, query, analyze, display and
output geographic information.
 GIS makes it possible to integrate different
kinds of geographic information :
 Digital maps,
 Aerial photographs,
 Satellite Images and
 Global positioning system (GPS) data
along with associated tabular database
information/Attributes

5. Components
 GIS involves complete understanding about Patterns, Space, and
Processes or Methodology needed to approach a problem.
 Links locational and database information and enables a person to
visualize patterns, relationship and trends.

7. Transforming real World Geographic Objects to Objects on
Computer
1.Representation of Geographic Reality
-Through the use of data models
2.Linking Attributes to geographic representation
3.Spatial relationship between geographic representations
Vector and Raster Data Models

8. How GIS works?
-5 step process by ESRI
Ask
What is the problem you are trying to solve or analyze, and where is it located?
Acquire
Find the data needed to complete your project.
Examine
Thorough examination of how the data is organized, how accurate it is and
where the data came from.
Analyse
Geographic analysis is the core strength of GIS. Depending on your project,
there are many different analysis methods.
Act
Share your results through reports, maps, tables, and charts and delivered in
printed format or digitally over a network or on the web.

9. What can we do with GIS???

10. 3D Modelling of Cities
People in thousands of organizations in many different
industries use ArcGIS in a wide range of applications.

11. Traffic Simulation using GIS
Transforming GIS Data into Functional Road Models for Large-Scale Traffic Simulation

12. Watershed Delineation
Volume Calculation of a Reservoir

13. GIS and Politics: Presidential election results

14. It provides a powerful medium for managing,
visualizing, and communicating about our world.

15. Evolution of GIS has transformed and revolutionized the ways in which
Planners, Engineers, Managers etc. conduct the management and
analysis of geospatial data.

GIS TRAINING COURSE

17. For this training session:
We will be using ArcGIS Desktop 10, later version of a popular
GIS software produced by ESRI.
This course is meant to teach some fundamental GIS operations
using ArcGIS.
It is not meant to be a comprehensive course in GIS or
ArcGIS.

18. ArcGIS
- By Environmental System Research Institute Inc., Redlands, CA (ESRI)'s
A family of GIS products that forms a complete Geographic Information
System (GIS) on industry standard.
Four primary frameworks of GIS are:
ArcGIS Desktop—Professional GIS applications composed of three
main software products:
 ArcView, ArcEditor, and ArcInfo
Developer GIS—Embeddable software components for developers to
extend GIS applications
Mobile GIS: ArcPad, and ArcGIS Mobile for field computing.
Server GIS: ArcIMS, ArcGIS Server, and ArcGIS Image Server

19. ArcGIS Desktop is comprised of a set of integrated applications:
• ArcMap , ArcCatalog and ArcToolbox.
ArcMap
Main mapping application which allows you to create maps, query
attributes, analyze spatial relationships, and layout final projects.

20. ArcCatalog
Organizes spatial data contained on your computer and various
other locations and allows for you to Search, Preview, and Add
data to ArcMap as well as manage Metadata.

21. Easily accessed and used within ArcMap and
ArcCatalog.
ArcToolbox contains tools for geoprocessing,
data conversion, coordinate systems,
projections and many more.

for a day; Teach a man to fish and you
feed him for a lifetime.”

23. We hope this seminar will get you started
using GIS and excited about learning
