Massachusetts Office of Geographic Information (MassGIS) is the Commonwealth of Massachusetts's central spatial data office responsible for producing, maintaining, and distributing geospatial information for Massachusetts Bay, Plymouth County, Berkshire County, Suffolk County, and other jurisdictions. MassGIS supports mapping, analysis, and planning activities used by agencies such as the Executive Office of Technology Services and Security, the Massachusetts Department of Transportation, the Massachusetts Department of Environmental Protection, the Massachusetts Department of Conservation and Recreation, and regional entities like the Merrimack Valley Planning Commission. Its datasets underpin projects involving the National Oceanic and Atmospheric Administration, the United States Geological Survey, the Federal Emergency Management Agency, the Environmental Protection Agency, and academic partners including the University of Massachusetts Amherst and Harvard University.
MassGIS originated amid spatial data initiatives influenced by national programs such as the Federal Geographic Data Committee and federal actions like the Geographic Information Systems Act in the late 20th century, aligning with regional efforts led by entities such as the New England Interstate Water Pollution Control Commission and the Northeast Regional Data Center. Early collaborations with the United States Geological Survey and municipal offices in Boston, Massachusetts and Worcester, Massachusetts produced foundational layers like the United States Geological Survey National Hydrography Dataset analogs and base cartography used in floodplain mapping for the National Flood Insurance Program. Over time MassGIS expanded to incorporate aerial imagery programs coordinated with vendors and partners including the National Aeronautics and Space Administration, the United States Department of Agriculture, and state university research centers, and was shaped by policy developments influenced by the Massachusetts Open Records Law and procurement standards tied to the Commonwealth of Massachusetts.
MassGIS operates within the administrative structure of the Executive Office of Technology Services and Security and coordinates with executive agencies such as the Massachusetts Department of Transportation and the Massachusetts Emergency Management Agency. Its governance framework references standards promulgated by the Federal Geographic Data Committee, and it participates in interagency working groups alongside the Massachusetts Office of Energy and Environmental Affairs, the Massachusetts Department of Public Health, and municipal associations like the Massachusetts Municipal Association. Technical oversight and strategic direction are influenced by collaborations with research institutions including the Massachusetts Institute of Technology and policy inputs from legislative bodies such as the Massachusetts General Court. Funding and budgeting interact with statewide fiscal entities including the Massachusetts Department of Revenue and grantors like the Environmental Protection Agency and the United States Department of Housing and Urban Development.
MassGIS maintains statewide datasets used by planners, engineers, and scientists, including orthophotography integrated with United States Geological Survey frameworks, elevation models linked to National Elevation Dataset standards, parcel and cadastral layers interoperable with county assessors in Middlesex County, Essex County, and Norfolk County, and hydrography datasets compatible with National Hydrography Dataset practices. Its services include web mapping portals interoperable with Esri, OpenStreetMap, and GeoServer platforms, geocoding services used by the Massachusetts Bay Transportation Authority, and metadata compliant with ISO 19115 and Dublin Core frameworks. MassGIS distributes data products supporting hazard analysis for the Federal Emergency Management Agency, land use planning with inputs from the United States Department of Agriculture, and conservation projects tied to the National Park Service and local land trusts.
MassGIS operates enterprise GIS infrastructure that integrates servers, databases, and cloud services from vendors and standards bodies such as Esri, Amazon Web Services, PostgreSQL, and the Open Geospatial Consortium. Its technical stack supports spatial data infrastructures compatible with the National Spatial Data Infrastructure and provides APIs for developers working with toolkits like Leaflet (JavaScript library), MapServer, and QGIS. High-performance processing for statewide orthophoto mosaics and LiDAR-derived products leverages compute resources coordinated with the University of Massachusetts Amherst and state data centers, and aligns with metadata and catalog services influenced by the Federal Geographic Data Committee and the Open Geospatial Consortium's catalog standards.
MassGIS datasets and tools are applied across emergency management workflows used by the Massachusetts Emergency Management Agency and Federal Emergency Management Agency for floodplain and storm-surge modeling, transportation planning by the Massachusetts Department of Transportation and regional transit authorities including the Massachusetts Bay Transportation Authority, public health mapping undertaken by the Massachusetts Department of Public Health and municipal health departments, and environmental conservation projects led by the Massachusetts Department of Conservation and Recreation and nonprofit organizations like the Nature Conservancy. Academic researchers at Harvard University, Boston University, and Tufts University use MassGIS data for urban analytics, climate resilience studies referencing the Intergovernmental Panel on Climate Change, and ecological research linked to the United States Fish and Wildlife Service.
MassGIS collaborates with federal partners such as the United States Geological Survey and the National Oceanic and Atmospheric Administration, academic institutions including University of Massachusetts Boston and Northeastern University, municipal governments across Plymouth County and Hampden County, regional planning agencies like the Metropolitan Area Planning Council, and nonprofit organizations like the Mass Audubon and the Conservation Law Foundation. It participates in multi-state initiatives with neighboring state agencies in Connecticut, Rhode Island, and New Hampshire and contributes to national interoperability efforts steered by the Federal Geographic Data Committee and the Open Geospatial Consortium.
MassGIS provides public access to many datasets via downloadable formats aligned with standards favored by Esri and open-source communities such as GeoJSON and Shapefile (ESRI) while applying licensing frameworks cognizant of the Massachusetts Open Records Law and state procurement rules overseen by the Commonwealth of Massachusetts. Distribution policies balance open-data principles championed by advocates such as the Sunlight Foundation with data sensitivity concerns involving agencies like the Massachusetts Department of Public Health and critical infrastructure stakeholders including the Massachusetts Department of Transportation. Users access data through portals interoperable with ArcGIS Online, Amazon Web Services, and open platforms like OpenStreetMap, subject to terms that reflect legal and technical guidance from the Massachusetts Attorney General and statewide policy offices.
