Introduction to Geographic Information System(GIS)
DAY 1
What is GIS???
Software
GIS ….. (misconceptions)???
A Map making tool

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
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.
GIS
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
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?
AcquireFind the data needed to complete your project.
ExamineThorough examination of how the data is organized, how accurate it is and
where the data came from.
AnalyseGeographic analysis is the core strength of GIS. Depending on your project,
there are many different analysis methods.
ActShare your results through reports, maps, tables, and charts and delivered in
printed format or digitally over a network or on the web.
What can we do with GIS???
3D Modelling of Cities
People in thousands of organizations in many different
industries use ArcGIS in a wide range of applications.

Traffic Simulation using GIS
Transforming GIS Data into Functional Road Models for Large-Scale Traffic Simulation
Watershed Delineation
Volume Calculation of a Reservoir
GIS and Politics: Presidential election results
It provides a powerful medium for managing, visualizing, and communicating about our world.
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
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.
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
ArcGIS Desktop is comprised of a set of integrated applications:
• ArcMap , ArcCatalog and ArcToolbox.
ArcMapMain mapping application which allows you to create maps, query
attributes, analyze spatial relationships, and layout final projects.
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.
Easily accessed and used within ArcMap and ArcCatalog.
ArcToolbox contains tools for geoprocessing, data conversion, coordinate systems, projections and many more.
ArcToolbox
“Give a man a fish and you feed him for a day; Teach a man to fish and you
feed him for a lifetime.”
We hope this seminar will get you started using GIS and excited about learning
more
