Fall NEARC

The 2017 Fall NEARC Conference will be held Sunday, November 5 - Wednesday, November 8 at the Newport Marriott in Newport, Rhode Island.

NEARC is not just for the GIS faithful. Yes, NEARC is for GIS practitioners, but NEARC is for anyone who wants to see the value GIS technology brings to their own environment and the world. This conference is very valuable for new users as well as those who have been using GIS for many years.

Data updates

  • 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.
