Maps and apps

  • Sexual Assault and Domestic Violence Resources Viewer: View resources across MA for survivors of sexual assault and domestic violence

    Sexual Assault and Domestic Violence Web App
    This webapp was created by MassGIS for the Governor’s Council to Address Sexual Assault and Domestic Violence. It contains housing support, rape crisis centers, hospitals with a Sexual Assault Nurse Examiner (SANE) program, and District Attorney's offices. It also contains the Filter and Near Me widgets to help survivors find facilities relevant to them.
  • Statewide Property Sales Viewer: View property sales from the past fiscal year across the state

    Statewide Property Sales Viewer interactive map

    The Statewide Property Sales Viewer maps real estate sales assembled by the State's Bureau of Local Assessment (part of the Division of Local Services).  The source is the annual "LA3" sales reports provided by municipal assessors. On the Division of Local Services website, these sales can be searched by property type, range of sale date or price, and other characteristics. You can download the search results. This MassGIS sales viewer application supports the same search criteria and then maps the result, color coding the sales based on their assessment-to-sale ratio. You can also still see and download the tabular result.

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

    Ortho time series

    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.


Governor Healey proclaimed November 15, 2023, as GIS Day. See the proclamation.
