MassGIS' standardized assessors’ parcel mapping data set contains property (land lot) boundaries and database information from each community's assessor.The data were developed through a competitive procurement funded by MassGIS. Each community in the Commonwealth was bid on by one or more vendors and the unit of work awarded was a city or town. The specification for this work was Level 3 of the MassGIS Digital Parcel Standard.This feature service contains three feature classes and one table.Map service also available.See the datalayer page for full details.

This feature service stores telephone area codes for each municipality and reflects the addition of four "overlay" codes in Massachusetts which took effect on April 2, 2001. For more information on the Commonwealth's area codes, see Verizon's Area Codes Lookup Web page. Also see the Secretary of State's Area Code Regions map.

The U.S. Geological Survey has conducted geologic mapping to characterize the sea floor offshore of Massachusetts. The mapping was carried out using a Simrad Subsea EM 1000 Multibeam Echo Sounder on the Frederick G. Creed on four cruises conducted between 1994 and 1998. The mapping was conducted in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and with support from the Canadian Hydrographic Service and the University of New Brunswick. The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) project that presents images and grids of bathymetry, shaded relief bathymetry, and backscatter intensity data from these surveys that will serve the needs of research, management and the public.

This is a seamless bare earth digital elevation model (DEM) created from lidar terrain elevation data for the Commonwealth of Massachusetts. It represents the elevation of the surface with vegetation and structures removed. The spatial resolution of the map is 1 meter. The elevation of each 1-meter square cell was linearly interpolated from classified lidar-derived point data.This version of the DEM stores the elevation values as integers. The native VALUE field represents the elevation above/below sea level in meters. MassGIS added a FEET field to the VAT (value attribute table) to store the elevation in feet as calculated by multiplying VALUE x 3.28084.Dates of lidar data used in this DEM range from 2010-2015. The overlapping lidar projects were adjusted to the same projection and datum and then mosaicked, with the most recent data replacing any older data. Several very small gaps between the project areas were patched with older lidar data where necessary or with models from recent aerial photo acquisitions. See https://www.mass.gov/doc/lidar-project-areas-original/download for an index map.This DEM is referenced to the WGS_1984_Web_Mercator_Auxiliary_Sphere spatial reference.See the MassGIS datalayer page to download the data as a file geodatabase raster dataset.View this service in the Massachusetts Elevation Finder.

Visit this website for an explanation of the parcel's assessing info: https://www.mass.gov/info-details/massgis-data-property-tax-parcels#attributes-Through a series of joins, spatial joins and select by location with various datasets, the following key attribute fields were populated in the Municipal Properties dataset.Open Space/Conservation Land Attributes are: OS_ID OS_ID is a unique ID for polygons in the open space/conservation land database, [Fee_Owner], [Level_Protection], OLI_1_INT. For an explanation of the coded values used in these fields, visit: https://www.mass.gov/info-details/massgis-data-protected-and-recreational-openspace#attributes-Zoning info for the parcel is contained within [ZONECODE], [MinLot_ac], and [SubStd_Sz]. Zonecode assigned to a parcel is based on the location of the center point of the parcel. The minimum lot size is per the Town's zoning bylaws. Parcel's smaller than the bylaws minimum lot size were assigned a 'yes' value in the Substandard Size attribute column.The attribute [vacant] was assigned a 'yes' value if the assessor's Building Value > $0.00 for the parcel OR the parcel contained one or more structures per the MassGIS structures dataset.The attribute [conserved] was assigned a 'yes' value if the parcel's center point coincided with a parcel in the Dukes County Open Space & Conservation Land dataset.The attribute [AbutPot] Abutter Potential is assigned a 'yes' value if any of the following attributes contain a 'yes' value: [AbutMuni], [AbutOS], or [AbutVacPrv].The attribute [Notes] were manually added by the GIS staff based on local knowledge.Attributes dealing with Abutters: [AbutMuni] indicates if the municipal owned parcel abuts other municipally owned parcels. 'Abuts' are any parcels that thouch (share a boundary) or are within 40ft of each other. [AbutOS] indicates if the municipal owned parcel abuts a parcel which is open space/conservation land. [AbutVacPrv] indicates if the municipal owned parcel abuts a parcel which is vacant residential land. "Vacant Residential Land" was identified by the assessor's Use Code = 1300 or 1310 for the parcel.Identifying Neighbors: All municipal parcels were buffered 40ft and dissolved together. Then that resulting multi-part dataset was 'exploded' so each distinct polygon was represented by a distinct record in the attribute table. Each polygon was assigned an ID number. This output is the "Municipal Property Clusters".Via a Spatial Join, the respective Cluster (aka group ID) was assigned to the respective municipal parcel. Similarly, by finding the (a) Vacant Residential properties and (b) Conservation Land properties that intersected with the Municipal Property Clusters, the Cluster/Group ID was assigned to the respective vacant residential properties and conservation land properties. A & B each have a distinct dataset which is included in this bundle of data.By having the Group ID in the Municipal Properties dataset and the Vacant Residential and Conservation Land datasets ...let's say a parcel has a Group ID = 3 --> then you can find the abutters by finding the other Municipal Parcels with a Group ID = 3 AND look in the Vacant Residential attribute table for Group ID = 3 AND look in the Conservation Land attribute table for Group ID = 3 --AND then you have tons of info at your fingertips regarding that municipally owned parcel and its abutting vacant properties.

The mission of the USGS Gap Analysis Program (GAP) is providing state, regional and national assessments of the conservation status of native vertebrate species and natural land cover types and facilitating the application of this information to land management activities. The PAD-US geodatabase is required to organize and assess the management status (i.e. apply GAP Status Codes) of elements of biodiversity protection. The goal of GAP is to 'keep common species common' by identifying species and plant communities not adequately represented in existing conservation lands. Common species are those not currently threatened with extinction. By identifying their habitats, gap analysis gives land managers and policy makers the information they need to make better-informed decisions when identifying priority areas for conservation. In cooperation with UNEP-World Conservation Monitoring Centre, GAP ensures PAD-US also supports global analyses to inform policy decisions by maintaining World Database for Protected Areas (WDPA) Site Codes and data for International Union for the Conservation of Nature (IUCN) categorized protected areas in the United States. GAP seeks to increase the efficiency and accuracy of PAD-US updates by leveraging resources in protected areas data aggregation and maintenance as described in "A Map of the Future", published following the PAD-US Design Project (July, 2009). While PAD-US was originally developed to support the GAP Mission stated above, the dataset is robust and has been expanded to support the conservation, recreation and public health communities as well. Additional applications become apparent over time.

MassGIS created the layer from a list received in January 2025 from the MBLC of libraries that are members of the Massachusetts Library System (MLS). The list was cross-referenced to points in our Master Address Database to create this geospatial layer. This layer also includes a small subset of "special" libraries as categorized by the MBLC whose main function is to operate as a library. Many schools, hospitals, trial courts, law offices, historical societies, museums, private companies and other public and private institutions house libraries in addition to their primary operations. They are not included in this data layer. MassGIS has separate layers for some of these types of facilities. Search the MBLC Library Directory for more.More details...Map service also available.

Gives property, or parcel, ownership together with value information, which ensures fair assessment of Boston taxable and non-taxable property of all types and classifications. To preserve their integrity, the identifiers PID, CM_ID, GIS_ID, ZIPCODE, and MAIL_ZIPCODE all are marked with an underscore ("_") as the last character.

Year-specific documentation for the FY2008 through FY2013 files is not currently available, but the format of those files is equivalent to that described in the FY2014 documentation.

The political boundary datalayer is a polygon representation of town boundaries created from arcs developed from survey coordinates extracted from the 68-volume Harbor and Lands Commission Town Boundary Atlas for the 351 communities (cities and towns) in Massachusetts. The Atlas was published in the early 1900's and is maintained by the Survey Section of Massachusetts Highway Department. For communities with a coastal boundary, MassGIS has collaborated with Massachusetts Water Resources Authority and the Department of Environmental Protection to complete a 1:12000 scale coastline. The boundary for the coastline was defined as being the upland side of tidal flats and rocky inter-tidal zones. Note that the 351 communities are the official municipal names, not including "villages" or other sections of towns. Note: Complete metadata is available within the downloaded zip file. This metadata can be viewed with ESRI ArcGIS software, and can be exported to FGDC and ISO metadata formats.

A Massachusetts Farmers’ Market is a public market for the primary purpose of connecting, and mutually benefiting, Massachusetts farmers, communities and shoppers while promoting and selling products grown and raised by participating farmers.The Farmers' Markets layer is derived from the Farmers’ Markets database maintained by the Mass. Department of Agricultural Resources. The Department provides technical assistance to individuals and groups trying to start a farmers' market, helps farmers find appropriate farmers' markets to participate in, and encourages consumers to patronize farmers' markets through various publications, including the MassGrown Map, which also pulls data from the Farmers’ Markets database.As well as basic information about the markets, this data layer includes information about participation in the food assistance programs Supplemental Nutrition Assistance Program (SNAP) and Farmers’ Market Nutrition Program (FMNP) (see Attributes below). Women, Infants and Children Cash Value Vouchers (WIC-CVV) are not currently redeemable at farmers markets.The data in this map service are current as of July 26, 2023.
