What are GIS eMaps?

A Geographic Information System (GIS) is a computer system that allows you to map, model, and analyze large amounts of data by location. GIS displays information as a series of layers that can be linked together by a common location element such as a street address or road name, latitude and longitude coordinate, or a zip code. Dozens of map layers can be arranged to show information such as, schools, vehicle emissions testing sites, air quality, landfills, political jurisdictions and much more.

ADEQ created the following eMaps using GIS to make environmental data and information available to the public for:
