GIS Resources for Land Trusts

GIS Service Centers

Beginning with Habitat

Provides wildlife related GIS data, maps and technical assistance; downloadable digital maps and accompanying information about important habitat features, as well as additional information and tools to implement habitat conservation in local land use planning efforts; currently developing a GIS co-occurrence model that allows users to weight the habitats and other important values present and helps identify local focus areas based on the habitats present and how a trust or group has valued them

Gulf of Maine Coastal Program

Works with any land trust or town throughout Maine to help prepare maps and habitat information for land protection efforts, including grants; with land trusts in the Casco Bay Watershed, Kennebec Estuary / Merrymeeting Bay and Downeast to:

  • develop and maintain a detailed database and GIS of conservation and public lands
  • provide regional and local maps of those lands, including a database printout
  • provide GIS data (conservation and public lands, BwH data, trails, infrastructure, and base data [roads, town boundaries, hydro, etc.]) that can be used with ArcGIS Explorer (free GIS software) or ArcGIS.

The Center for Community GIS

Provides specialized community-focused mapping services (GIS, GPS, cartography, training, facilitation) to public interest organizations working in the areas of natural resources management, conservation, tourism, economic development, public health, and education.
