GIS at Maine Department of Environmental Protection
What is GIS?
GIS is an acronym for Geographic Information System. A GIS is a combination of computer applications and databases which allow users to create maps and conduct various spatial and attribute analyses.
Why use GIS?
MEDEP staff use GIS for a wide variety of needs, typically to answer spatial questions about the resources we regulate. Examples would include mapping groundwater contamination at a site, modeling ozone air pollution, or determining control methods for invasive species in Maine lakes.
The Maine DEP GIS Unit offers selected data, geographically referenced, from a number of the department's databases to the public via Google Earth and in other formats.
