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.
