                        What is GIS?
   A geographic information system (GIS) is a computer-based tool for
    mapping and analyzing things that exist and events that happen on Earth.
    About 80% of all data have a spatial component.


   GIS technology integrates common database operations such as query
    and statistical analysis with the unique visualisation and geographic
    analysis benefits offered by maps.


    GIS is more than just data and maps.
    GIS is…
    “an organized collection of computer hardware, software, data, and
    personnel designed to efficiently capture, store, update, manipulate,
    analyze, and display all forms of geographically referenced information.” -
    -ESRI

   It is customizable to meet the application needs of the users forming a
    powerful network of information that facilitates the sharing of data for
    better decision-making.
            Simply said:
Geographic »       maps
Information »      data
System      »      digital

 A GIS links information to geographic
 location (connects the what to the where),
 allowing you to seek patterns and
 relationships that may not otherwise be
 apparent.
     What GIS Can Do for You?
   Capture
   Storage
   Query
   Analyze
   Display
   Output
    Major Companies Using GIS
   Federal Agencies       Ace Hardware
   Chase Manhattan        Gold’s Gym
   Sears Roebuck &        US Postal Service
    Co.                    Minolta Corp.
   Domino’s Pizza         Conectiv
   Realtor.com            UPS
   MBNA                   AAA
   Metropolitan Life      State/Local Gov’t
   Police and Fire
    Depts
                 GIS uses more than
                just geographic data:
Start with geographic data, such as a county
Attribute data that has a relationship to this county can
  include:
 mean monthly humidity

 average rainfall

 average feet of beach erosion per year

 population and demographics

 zip codes, census tracts, etc.


By mapping more than one county that has these attributes, a
new map can be produced to show the comparison between
the attribute data.

                  Data
        Possibly the most important
      component of a GIS is the data.

A GIS will integrate spatial data with other
  data resources, such as spreadsheets
  used by most organizations to organize
  and maintain their data, to manage
  spatial data.
         A bit about data
Layers can be
  features or
  surfaces
                              Polygons




                   Lines
