What is GIS?
A Geographic Information System (GIS) is a computer system that manages data identified by their locations (geographically referenced). Examples of GIS data are county boundaries, land use, and pollution-monitoring locations. With GIS, data can be displayed, assembled, stored, and manipulated. Such data are frequently displayed as maps.
GIS technology can be used for scientific investigations, natural resource management, and development planning. For example, a GIS system could:
1. Allow emergency planners to easily calculate emergency response times in the event of a natural disaster.
2. Use water quality and land use data to identify wetlands that need protection from pollution.
3. Create presentation-quality maps.
