Maps and apps

  • 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
