    • Protected and Recreational Open Space
      December 14, 2017 - 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 descriptive geography to almost 4,900 polygons in 140 municipalities.

      New shapefile and personal geodatabase data have been placed on our ftp site, representing data updated as of 12/14/2017.

      The details:
      • Updates involve improving the boundaries of recreational areas and protected open spaces. Conservation Areas, Cemeteries, Golf Courses, Recreational and/or Historic Parkland, and Conservation Restrictions were added (or deleted if determined to be erroneously digitized). The work resulted in a net gain of over 2,700 acres.
      • Major updates were performed on almost 50 projects that involved Land and Water Conservation Funds affecting almost 250 acres.
      • Town-wide updates were performed in Chelmsford, Marlborough, and Norwood.
      • Several EEA land acquisition projects completed for FY2018 are starting to be added to the Protected and Recreational Open Space database. The projects included watershed preservation restrictions, conservation restrictions, and fee-simple acquisitions.
      • The Department of Agricultural Resources added or otherwise improved the boundaries of 20 agricultural preservation restrictions affecting 514 acres.
      • The Department of Fish and Game performed edits in 10 towns that increased the overall acreage in the database by almost 260 acres.
      • The Department of Conservation and Recreation – Water Supply Division enhanced the descriptive geography of 1,127 polygons to include FY funding of older projects in 37 towns.
      • Additional digitizing was completed for EEA-sponsored programs.
        • One LAND grant was added for 60 acres
        • Four acquisitions that involved the Conservation Land Tax Credit program affected 53 acres in 4 municipalities
      • Other minor ad hoc adjustments to database attributes and boundaries were performed in 88 municipalities.
         
    • MassDEP Wetlands changes
      December 14, 2017 - The current data are now called “MassDEP Wetlands (2005).” These statewide layers, based on photointerpretation of 2005 aerial photography, enhance and replace the original MassDEP wetlands layers, formerly known as DEP Wetlands (1:12,000).

      The older data are now named “MassDEP Wetlands Original (1:12,000).” These “original” data layers are being maintained for reference purposes only.

      A new layer, “MassDEP Wetlands (2005) Human Altered Areas,” contains wetland areas that were changed due to human activity. This layer stores the former type of the wetland.
       
    • Six MassDEP data layers
      October 23, 2017 - The MassDEP GIS Group has updated the Public Water Supplies, wellhead (Zone II, Zone I, IWPA) protection areas, Chapter 21e Sites and AUL Sites data, all available from MassGIS.
    • Building Structures (2-D)
      October 4, 2017 - Downloads for all 351 communities were replaced, as we performed statewide edits during the summer to synchronize the data with our master address database using 2016 ortho imagery. Some polygons were removed where it was apparent that the structures have been demolished. Many polygons were added where we had address points but no corresponding structure polygons. The total net gain was about 2,800 polygons.
    • ZIP Codes (5-Digit) from HERE (Navteq)
