A bit different from my usual uploads. But say what. Pretty basic explanations and points. Did this for a course on educational technology a while back.

3. INTRODUCTION TO GEOGRAPHIC
INFORMATION SYSTEMS
• The first GIS was created in 1962 in Canada by the
federal Department of Forestry and Rural Development.
• It was developed by Dr Roger Tomlinson and called
the Canada Geographic Information System.
• GIS is mostly targeted towards organizations.

4. DEFINITION
 WHAT IS A GEOGRAPHIC INFORMATION
SYSTEM?A Geographic Information System (GIS) is a
collection of computer hardware, software
and geographic data used to analyse and
display geographically referenced
information.

5. GIS SOFTWARE PACKAGES
 The most popular GIS software packages are:
 ESRI
 MapInfo
 IDRISI
 Manifold
 InterGraph GeoMedia
 SmallWorld
 GRASS
 MS MapPoint
 ERDAS Imagine

6. WHAT CAN GIS DO?
Map Locations
Mapping where things are lets you find places that have
the features you're looking for, and to see where to take
action.
GIS lets you:•Find a feature on a map
•Find patterns of distribution on a map

7.  Map Quantities
WHAT CAN GIS DO?
(CONTINUED)
• People map quantities (like where the most and least are)
to find places that meet their criteria and take action, or to
see the relationships between places.
• This gives an additional level of information beyond
simply mapping the locations of features.

8.  Map Densities
WHAT CAN GIS DO?
(CONTINUED)
•A density map lets you measure the number of features
using a uniform area unit, such as acres or square miles, so
you can clearly see the distribution.
•Mapping density is especially useful when mapping areas,
such as census tracts or counties, which vary greatly in
size.

9. APPLICATIONS OF GIS
The possible applications of such a tool would be
vast in number, but here are a few examples of the
possible uses of GIS:
• Earthquake Mapping
• Market Research
• Demographics
• Health
• Research
• Census
Data
