2. What is GIS?
G stands for geographic, so we know that GIS has something to do
with geography.
I stands for information, so we know that GIS has something to do
with information, namely geographic information.
S stands for system, so we know that GIS is an integrated system
Of geography and information tied together.
Most people agree that over 80% of the information related to
government operations have a geographic component. Therefore, a
system that integrates this inform action together is quite valuable.
We shall see how a geographic in formation system tied geography
and information together....

3. What is GIS?
Information about places on the earth’s surface
Knowledge about where something is located
Knowledge about what is at a given location
Can be very detail
Stands for “Geographical informational system”(GIS)
Is a special kind of “information system ”information system are
used to work(Manipulation, summarize, query, edit, visualize) with
information store in computer database
User special information about what is where on the Earth’s
Surface.

4. Purpose of GIS
The purpose of GIS is to create, share, and apply useful map-
based information products that support the work of
organizations as well as to create and manage the supporting
geographic information.
Geographic Information Systems support the following:
Visual communication
allowing patterns and anomalies to be quickly identified
Automating activities involving geographic location
 Better decision making and planning through querying
Mapping, analyzing, & modeling with the whole picture`

6. GIS Data Type
Two Major Types of GIS Data
 Raster Data- Grid Base, Feature are represent as
square cells in a grid.
 Data stored is usually numeric
Vector Data- Feature are represented as point, line
and polygone, information about a feature is stored in
an attribute table.
- Coordinate Based( Cartesian, Polar, 3D, Linear)-
-Topological
-Object Oriented

9. GIS Data Type
Vector Format:
1. Shapefile Contains:
 Point, or multi-point
 Line, or polyline
 Polygon
2. Coverage Contains:
 Point, or node
 Arc, or line
 Polygon
 Label

10. What do you need to use GIS?
A full GIS, or geographic information system, requires:
•Hardware (computers and peripherals)
•Software
•Data
•People
•Methods
A Geographical Information links Location(Spatial)
and Database(Tabular) information and enable a
person to visualize patterns, relations and trends.
This process gives an entirely new perspective to
data analysis.

11. GIS Software?
Types of GIS software
Desktop GIS
Server GIS
Developer GIS
Hand-held
Others (e.g. CAD-based GIS)
Internet GIS

13. ArcGIS Module
GIS software products for building a complete GIS. It consists
of a number of frameworks for deploying GIS:
– ArcGIS Desktop: an integrated suite of professional
GIS applications
– ArcGIS Engine: embeddable developer components
for custom GIS applications
– Server GIS: ArcSDE®, ArcIMS®, and ArcGIS Server
– Mobile GIS:ArcPad® as well as ArcGIS Desktop and
Engine for Tablet PC computing

14. ArcGIS Desktop
ArcView – view data and do edits on shape files
ArcEditor – midlevel software suite designed for
advanced editing of spatial data
ArcInfo – data building, modeling, analysis

Table of Contents
The ArcMap Table of Contents contains three tabs,
each with its own function.
• Display tab
• Arrange layers, view legends, expand and
collapse layer views. Does NOT list tables.
• Source tab
• View the GIS file source of the layer. Lists
tables.
• Selection tab
• Turn selectable layers on and off.
