GIS Data Distribution

MEDEP staff generate and utilize a large amount of GIS data.  Non-MEDEP GIS data are typically distributed by the Maine Office of GIS.

MEDEP GIS Data is now being distributed using Google Earth (above).  If you can't find the data you are interested in contact John Lynam.

GIS Data Collection

The MEDEP GIS Unit coordinates the collection and submittal of GIS data from MEDEP program staff and environmental consultants.  This data supports the geographic evaluation of sites and study areas in conjunction with environmental sampling data.  A set of Spatial Data Collection Guidelines is now available to assist with submittal of data to the MEDEP Spatial Database.
