DEP Google Earth Interactive Maps

The Maine DEP GIS Unit is now offering selected data, geographically referenced, from a number of the department's databases to the public via Google Earth.  You will need to have Google Earth installed to view this data.  For help using Google Earth goto the Help Center.

Google Earth Statewide Data

The individual DEP Google Earth Map projects contain a number of statewide data layers.  Below is a list of those layers for download individually if they are needed for other Google Earth applications.  The links can also be used as Network Links in your own Google Earth projects.  Occasionally, to make the kmz files smaller for better performance, the data has been generalized and/or smoothed.

If you need to make detailed decisions using geospatial data please go to the Maine Office of GIS Data Catalog for the original data, downloadable in GIS format.

Downloading Data:  When downloadable data is available for GIS Users there are two options:
    Option 1:  Use the raw data file alternate links above to download a shapefile or text file.
    Option 2:  Click on the project or layer links in the Google Earth table of contents (Places window).  In the balloon, there will be a link to a text file with attribute data and spatial coordinates that can be imported into most GIS systems.

Feedback:  If you would like to comment on the use of Google Earth, provide suggestions for improving the functionality or report problems please go to our Feedback Form.

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 Chris Halsted (christian.h.halsted (at) maine.gov) or John Lynam (john.lynam (at) maine.gov).

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.
DEP GIS Maps


MEDEP GIS maps are used for a wide variety of reasons, including file documentation of issues at sites, providing evidence at hearings, for feedback at public meetings, and other reasons.  Some MEDEP GIS maps are available online in PDF format (you will need Adobe Acrobat Reader) Here are a few examples:
