Geographical Information Systems

By: Ryan Evans and Peyton Love

GIS is defined as a system which allows layers of data to be placed on map data to visualize and analyze it.

Layers of a GIS could include:

  • population densities
  • crime patterns
  • natural phenomena
  • average incomes
  • positions of facilities such police stations and hospitals

A GIS allows users to gather their own data from field research and add them as new layers using the data import tools.
