• MassGIS Imagery Time Series: 30 years of Massachusetts orthophotos.

  

  This app explains our ortho imagery acquisitions through the years and allows you to explore the various vintages in one location, from the black and white imagery of the 1990s to the 2019 high-resolution color imagery program.

• U.S. EPA Designated Sole Source Aquifers

• Community Boundaries (Towns) from Survey Points

• MHC Historic Inventory
  September 9, 2020 - For many years, the Massachusetts Historical Commission’s Historic Inventory of historic places (points) and historic districts (polygons) has been available for viewing and download on our website. Until now, because the data changes very frequently, the data download functioned as a “clip and ship”; when a user made the request for the data, a query was run upon the MHC’s online MACRIS Maps mapping application to create the file for the user. Now, MassGIS will be hosting static files that will be periodically updated.
• Protected and Recreational Open Space
  August 4, 2020 - Energy and Environmental Affairs GIS staff have updated the Protected and Recreational OpenSpace layers (arcs and polygons), available from MassGIS. Since the last publication to the web, staff at EEA and its associated agencies performed edits that improved the boundaries and/or attributes to over 400 polygons of recreational areas and open spaces in 79 municipalities.
  
  New shapefile and file geodatabase downloads represent data updated as of 6/24/2020.
  
  The details:
  • Updates involve adding or improving the boundaries of many types of recreational areas and protected open spaces. Twelve school athletic fields, 259 conservation areas, 9 cemeteries, 30 water supply lands, 8 parks, and 78 conservation restrictions, resulting in a net gain of more than 4,600 acres in the database.
  • The Department of Conservation and Recreation - Parks performed edits in 38 municipalities for fiscal years 2015, 2016 and 2017, adding over 1,400 acres.
  • The Department of Fish and Game performed edits in 8 towns, adding more than 194 acres.
