Description: 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.
Description: MxxxOthLeg contains polygons representing other “invisible” legal boundaries such as easements or private rights-of-way that overlap tax parcels.There may be few or even no features in this layer and it is required only if such boundaries are shown on the original assessors map. Only Entity Attributes are listed in this metadata. Please see the TaxPar feature class (or MxxxTaxPar.shp) for all other information.

Description: A polling place or polling location is where voters cast their ballots in elections. The relationship between voting precincts and polling places is maintained in the PrecinctPollingPlace table and this table should be used to manage the unique occurence of polling places to precincts; as well as occurences that require many voting precincts to be related to a single polling place.
Description: Massachusetts House Legislative Districts as signed into law on November 3, 2011. These districts were based on demographic data from the 2010 U.S. Census and are used for elections in 2012 and beyond until the districts are redrawn.Updated on January 7, 2019, with legislator changes from recent elections and vacancies. Minor edits were made to boundaries in Boston on March 7, 2018 to reflect corrected data from the City of Boston. In November 2018 MassGIS made minor edits to boundaries statewide where they were offset enough from survey-based municipal lines to result in address points being assigned to the wrong district. These boundary changes have not been incorporated into U.S. Census geography that forms the basis for this layer.

Description: This feature class depicts the U.S. Congressional District boundaries (Polygons) for Massachusetts as signed into law on November 21, 2011.In March 2018 MassGIS made minor edits to boundaries in Boston to reflect corrected data from the City of Boston. In November 2018 MassGIS made minor edits to boundaries statewide where they were offset enough from survey-based municipal lines to result in address points being assigned to the wrong district. These boundary changes have not been incorporated into U.S. Census geography that forms the basis for this layer. In January 2019, the layer was updated to reflect the results of the latest elections.

Description: This ArcGIS version 9.3.1 personal geodatabase was photogrammetrically compiled from aerial photography flown in the Spring 2009 by Fugro EarthData, Inc. Planimetric and DTM data was compiled in Summit Dat E/M software with MicroStation and imported into the personal geodatabase. The personal geodatabase includes 36 Feature Classes including Buildings, Edge of pavement, Hydro, Trees, DTM, contours etc. etc as described in process description. The compiled planimetric features are processed for cartographic representation at 1:40 scale to meet the National Map Accuracy Standards(NMAS).
Description: The MassGIS Protected and Recreational OpenSpace data comprise a set of related data layers that represent parklands, forests, golf courses, playgrounds, wildlife sanctuaries, conservation lands, water supply areas, cemeteries, school ball fields, and other open land that may be classified as protected and/or recreational in use. Not all lands in this layer are protected in perpetuity, though nearly all have at least some level of protection. The layer includes lands owned by the state, cities and towns, federal agencies, and private and non-profit entities. The following types of land are included in this polygon datalayer: - conservation land - habitat protection with minimal recreation, such as walking trails - recreation land - outdoor facilities such as town parks, commons, playing fields, school fields, golf courses, bike paths, scout camps, and fish and game clubs. These may be privately or publicly owned facilities. - town forests - parkways - green buffers along roads, if they are a recognized conservation resource - agricultural land - land protected under an Agricultural Preservation Restriction (APR) and administered by the state Department of Agricultural Resources (DAR, formerly the Dept. of Food and Agriculture (DFA)) - aquifer protection land - not zoning overlay districts - watershed protection land - not zoning overlay districts - cemeteries - if a recognized conservation or recreation resource - forest land -- if designated as a Forest Legacy Area The OpenSpace layer includes two feature classes: * OPENSPACE_POLY - polygons of recreational and conservation lands as described above * OPENSPACE_ARC - attributed lines that represent boundaries of the polygons These feature classes are stored in a feature dataset named OPENSPACE that includes ArcGIS geodatabase topology.

Description: The National Flood Hazard Layer (NFHL) data incorporates all Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters Of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA.The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all FIRM Databases and corresponding LOMRs available on the publication date of the data set. The specification for the horizontal control of FIRM Databases is consistent with those required for mapping at a scale of 1:12,000. This file is georeferenced to the Earth's surface using the Geographic Coordinate System (GCS) and North American Dataum of 1983 (NSRS-2007).The data in this layer, named FEMA_NFHL_POLY, include data published by FEMA as of July 21, 2014.
