Geographic Information Systems

What is a Geographic Information System (GIS)?

globe and gis

GIS is a way through computers to better understand the importance of space (aka Geography).

Geography is more than just maps that a GIS (Geographic Information Sytem) allows us to see.

A paper map is merely a static snap shot. Unlike a paper map, GIS allows us to interact with data behind the map.

GIS is the next step in the evolution of maps

What we can do with GIS?

  • Display (visualize) the data in a map (2D/3D)
  • Retrieve the information
  • Finding a location such as address
  • Control the display & Navigate map
    • Zoom in/out
    • Pan
  • Analyze space by combining the data from different sources
GIS provides a way of pairing unlikely causes and effects

The GIS Connection...

  • Internet mapping (getting from one place to another)
    • Google/Yahoo map
  • Store location decisions (how to get the most customers)
  • Hazardous Area determination (finding likely dangerous areas)
  • Environment (understanding the relationship between man and nature)
