A Geographic Information System or GIS is a computer system that allows you to map, model, and analyze large quantities of data within a single database based on location. ADEQ created a GIS tool to make environmental data and information accessible and available to the public.
This tool is often used by individuals and organizations, schools, governments, and businesses seeking information. GIS displays information as a series of layers that can be linked together by a common locational component such as physical street address or road name, latitude and longitude coordinate, or a postal zip code. Dozens of map layers can be arranged to display information about transportation networks, schools, vehicle emissions testing sites, air quality, landfills, political jurisdictions and much more.
The eMaps help will give you an overview of how to use eMaps. The eMaps tutorials describe some of the uses of eMaps that better demonstrate what can be done with it. The tutorials will walk you through GIS and help you find data if you've never used GIS before.
