This service shows the 6 regions for the Massachusetts Commission for the Blind. The data have contact information for each region.See https://www.mass.gov/info-details/massgis-data-massachusetts-commission-for-the-blind-regions for full metadata.

This polygon data layer contains the six Massachusetts Department of Transportation (MassDOT) Highway Districts in the Commonwealth of Massachusetts. The districts supervise all construction within its jurisdiction; performs on-site engineering; implements maintenance and preventative maintenance programs; generates proposals for maintenance and construction work; and provides engineering support to cities and towns.ProductionThe bounds of the MassDOT Highway Districts were digitized from the MassGIS survey-level town boundaries. In addition to the polygon layer, there is an arc layer following the sameline workas the polygon included in thedownloadableshape file.MetadataStatusThis data is current as of September 2013.

The Massachusetts Department of Transportation Highway Division Road Inventory contains the spatial linework for all the public and a good portion of the private roadways in Massachusetts, along with roadway attributes covering the roadway classification, ownership, physical conditions, traffic volumes, pavement conditions, highway performance monitoring information, and more. This version has been processed by CTPS to eliminate overlaps among features in the original distributed by MassDOT and to add pavement data, which is no longer attached by MassDOT.

Updated version of MassDOT's Potential for Everyday Biking data layer. The Potential for Everyday Biking and Walking layers display latent demand for active-mode trip making and are implemented in various project prioritization processes. Methodology documentation available here.

HOW TO USE:

The legend breaks road segments into three categories: high, medium, and low. High indicates the road segment is in the top 10% of potential, medium indicates the top 60%, with low rounding out the remainder.

Note: a road segment's appearance in the map represents demand and may already have existing walking or biking infrastructure.

This data layer contains the name and location of roads that the Federal Highway Administration has designated as Scenic Byways within the Commonwealth of Massachusetts. The Scenic Byways program supports roads that have outstanding scenic, historic, cultural, natural, recreational, and archaeological qualities.

This dataset provides information on work zones in the state of Massachusetts in a tabular format and is updated daily based on the live MassDOT Work Zone Data Exchange (WZDx) Feed.

A continuously updating archive of the MassDOT WZDx feed data can be found at ITS WorkZone Raw Data Sandbox and the ITS WorkZone Semi-Processed Data Sandbox. This live feed is currently compliant with the WZDx Specification v3.1.

The Land Use (2005) datalayer is a Massachusetts statewide, seamless digital dataset of land cover / land use, created using semi-automated methods, and based on 0.5 meter resolution digital ortho imagery captured in April 2005.The classification scheme is based on the coding schema used for previous Massachusetts land use datasets, with modifications.These data were prepared by Sanborn. The minimum mapping unit (MMU) is generally 1 acre, but a MMU as low as ¼ acre may be found in some areas, e.g. in urban areas where assessor parcels were used to enhance the mapping of multi-family residential areas.The formerly used “MacConnell” schema combined land cover and land use categories, and was designed for manual interpretation of aerial photos. In this project, that protocol was modified so that it was useful in an automated environment, but it still maintains much compatibility with the older system. The spatial accuracy of the current method is excellent, since the land use map is derived directly from the ortho image.Please see https://www.mass.gov/info-details/massgis-data-land-use-2005 for more details.Map service also available.

This political boundary layer is the most accurate representing the city and town boundaries in the Commonwealth of Massachusetts.This datalayer has been created from latitude and longitude coordinates found in the 68-volume Harbor and Lands Commission Town Boundary Atlas. This Atlas series, and updates since it was published, describes the legal boundary for each of the 351 municipalities in Massachusetts.
These coordinates were recorded from surveys of the location of each boundary marker around the periphery of each community. Each survey was tied into higher order monumented survey control points. The Atlases also include detailed descriptions of each community's boundary and location maps for each of the original boundary marker locations. The original surveys were conducted in the 1890s. The Atlas series was published in the early 1900s and has since been updated by the Survey Section of the Massachusetts Highway Department with changes as they are approved by the legislature.MassGIS staff collaborated closely with staff from the Survey Section during the development of this data layer. MassGIS staff keyed the coordinates into a database; that data entry was double-checked by staff from the Survey Section. Staff from the Survey Section then converted the latitude/longitude coordinates to the NAD83 datum and also created a version of the coordinates in state plane coordinates with units of meters. MassGIS used the state plane coordinates to "generate" points in ArcGIS. Boundary arcs from the existing USGS-derived municipal boundary data layer were then snapped to the survey-derived points. The differences between the municipal boundary arcs digitized from those on the USGS quads and those created by snapping to the survey-derived coordinates are typically plus or minus 12 feet, although these differences are sometimes less and sometimes more. Some municipal boundary arcs (about 15% of the total) follow the edge of a road or rail right-of-way or a stream or river channel. In these cases, the new boundary arcs were "heads up" digitized based on features visible on the statewide 1:5,000 color orthos from imagery flown in 2001. For communities with a coastal boundary, MassGIS collaborated with the Massachusetts Water Resources Authority and the Department of Environmental Protection to complete a 1:12,000 scale coastline.The boundaries are included in Esri's World Topographic Map through participation in its Community Maps program.City/Town names' labels are included in this service.(This service was published from a map document using the Web Mercator projection for the data frame.)For full metadata please see https://www.mass.gov/info-details/massgis-data-municipalities

In 2010, the Census Bureau used the Census Block Group data to designate the urban boundaries by following the Census Bureau maintained road segments called TIGER. The Office of Transportation Planning, in cooperation with the regional planning agencies, adjusted the boundaries to follow the Road Inventory street segments, municipal boundaries, railroads, or water bodies. This polygon datalayer represents the final version of the adjusted urban boundaries, which is used to determine the Road Inventory official roadway functional classification.ProductionThe urban boundaries were digitized with the aid of 1:5000 road inventory, rail lines, streams, and MassGIS survey-level town boundariesStatusThis data is current as of 2013.
