GIS Data and Maps

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.

Downloading Data:  For GIS Users who would like to download any of these datasets, 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 .txt 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

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).

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:
