Geographic Information System (GIS)

What Is GIS?

A Geographic Information System is an automated system that provides for the capture, storage, display, manipulation, and output of spatially referenced data.

In a GIS model:

  • Data is organized by layers
  • Each layer represents a common feature (transportation, soils, elevation…)
  • Layers are bound by a common reference system
