What is a Geographic Information System?

GIS stands for geographic information system. A GIS is made up of digital map layers, each with an underlying database. Each map layer has real world coordinates so that layers can be overlaid to view map layers in relation to other map layers. Each layer's database contains information about the map features in that layer. For example, the streets map layer contains information about whether a street is paved or unpaved.  This information is stored in the database for each street.  Database information can be queried or used to color-code the map. In addition, external databases can be joined to a map layer so that additional information can be displayed on a map. GIS is intelligent mapping.
