New MassGIS Data Hub

MassGIS Data Hub home page

MassGIS is proud to announce the formal launch of the MassGIS Data Hub!

Our vision for this open data portal is that it will serve as a "front door" where users can go to search for public, authoritative geospatial data services from MassGIS and other organizations across the Commonwealth. Anyone can search the Hub for data of interest by entering keywords, or by browsing featured content or data categories. The Hub features options for viewing the items in maps and downloading the data in several formats.

The site searches MassGIS's ArcGIS Online organization for map, feature, image, and tile services, along with web maps, applications, and dashboards. We've also added items from the Executive Office of Energy and Environmental Affairs and MassDOT.

We’d like to include your data too!

To make the Hub as useful as possible to the GIS user community, we extend an invitation to any organizations that would like their ArcGIS Online-based authoritative data to be discoverable in the MassGIS Data Hub. For us to consider your data for inclusion, you would need to create an ArcGIS Online Open Data group and publicly share it with Everyone. Include metadata and plenty of good keywords on the item details pages of your services for best results. Then, send Michael Trust the name of the group and he will review it. If included, users who search our Hub will be able to find your ArcGIS Online data and apps. Also, if you want our items discoverable in your Hubs, email Michael for the groups you would need to add to your Groups Manager.

Meet the new MassGIS Director and State GIO, and view Cy's GIS Day 2023 videos

Our new Director, Cy Smith, (who is also the state's first Geographic Information Officer) has arrived and is immersing himself in all things Massachusetts GIS. Welcome Cy!

To commemorate GIS day in 2023, MassGIS created a series of 5 videos that were published to social media. The purpose of the videos was to introduce the MassGIS Director, illuminate the importance of the hidden infrastructure of Geographic Information Systems, and to highlight some current and future uses of GIS.

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.
