  1. Title: MassGIS 2003 Massachusetts Land Use (January 2002)

    Contributors:

    Summary: The MassGIS Land Use datalayer has 37 land use classifications interpreted from 1:25,000 aerial photography. Coverage is complete statewide for 1971, 1985, and 1999. Additionally, more than half the state was interpreted from aerial photography flown during 1990, 1991, 1992, 1995 or 1997. The 15 towns on Cape Cod also contain land use data for 1951. Please see the Land Use Status Map (http://www.mass.gov/mgis/st_lus.htm), which displays the years for which land use data were interpreted for each town. The year of most recent photography used for land use data interpretation is stored in a single statewide coverage called LUSTAT (http://www.mass.gov/mgis/ftplus.htm). This layer was necessitated because some towns contain partial coverage for a certain year, which eliminated the one-to-one link between town-ID and year.

  2. Title: Street Trees (Town of Brookline)

    Contributors:

    Summary: The Street Trees layer is a point coverage inventory of each street tree in the Town of Brookline. Attributes described include species, diameter, condition, management need, growing conditions, predominant root zone cover, presence of utility or power lines, location (on the street or in a park), etc. The Brookline Street Tree Inventory was initially conducted in 1994 as a cooperative project of the University of Massachusetts at Amherst, U.S. Forest Service, Massachusetts Department of Environmental Management, and the Town of Brookline; other supporting organizations include the Harvard University Arnold Arboretum and the Brookline Green Space Alliance. The Town agencies involved in the project include the Conservation Commission, Tree Planting Committee, and the Department of Public Works. This project, thought to be the first comprehensive municipal street tree inventory based on GIS, recruited and trained over 100 citizens to perform the inventory. Teams of volunteers were assigned areas of the town in which to locate each street tree on the Town's Assessor's Maps for digitizing at a later time by UMass/Amherst.

  3. Title: MassGIS 2003 Massachusetts Priority Natural Vegetation Communities : Pine Barrens Natural Community Systems (UMass) (April 2003)

    Contributors:

    Summary: This datalayer contains polygons representing Massachusetts Priority Natural Vegetation Communities : Pine Barrens Community Systems produced by the University of Massachusetts at Amherst (UMass). The data covers only a portion of southeastern Massachusetts including the towns of Plymouth, Kingston, Bourne, Carver, and Wareham, Massachusetts. Pine Barrens Systems are a mosaic of pitch pine and scrub oak, with heath and grassy openings, located on nutrient-poor, acidic, drought-prone soils. Due to spatial accuracy issues, the UMass data should be used for regional analysis only, at scales of 1:30,000 and smaller. The datalayer can be used with the MassGIS datalayer: Priority Natural Vegetation Communities : Pine Barrens Community Systems, which covers a portion of eastern Massachusetts excluding the areas covered by this UMass datalayer. This layer is part of the MassGIS Priority Natural Vegetation Communities dataset, which depicts the distribution of the eight natural community systems identified by the Massachusetts Natural Heritage and Endangered Species Program (NHESP) as most critical to the conservation of the Commonwealth's biological diversity (Barbour et al., 1998).

  4. Title: Watersheet Plan, Boston Harbor, Massachusetts, 1998 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Boston Harbor watersheet plan, prepared for the city of Boston by Urban Harbors Institute, University of Massachusetts Boston. It was published by Urban Harbors Institute in 1998. Scale [ca. 1:3,000]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Massachusetts State Plane Coordinate System, Mainland Zone (in Feet) (Fipszone 2001). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, cities and other human settlements, territorial boundaries, shoreline features, and more. Includes also legend showing marine transportation, drainage, and landmark features. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

  5. Title: MassGIS 2000 Rail Trails Datalayer

    Contributors:

    Summary: The Rail Trails Datalayer is a line coverage representing abandoned railroad rights-of-way and public bike trails that use the rights-of-way. The dataset was created by the Massachusetts Department of Environmental Management for the purpose of regional planning and mapping. The data was originally modified by DEM from the MassGIS Railroads Datalayer; it has since been modified for DEM by the University of Massachusetts in 1997. All modifications were made using information from various paper maps, and much of the data came directly from USGS Topographic Quadrangles.

    Contributors:

    Summary: The Long Distance Trails Datalayer is a line coverage representing trails that are longer than 25 miles. The data was created for the purpose of regional planning and mapping by the Massachusetts Department of Environmental Management (DEM) and was modified for DEM by the University of Massachusetts in 1997.

  15. Title: (Composite Map) (Facsimile) Rocque's Map of London. 1746 (Raster Image)

    Contributors:

    Summary: This raster layer is a georeferenced image of a map titled "Composite Map: (Facsimile) Rocque's Map of London. 1746." Published in 1919, this composite map is considered one of the best facsimiles of the original Rocque Map ("A plan of the cities of London and Westminster, and borough of Southwark"), created by John Rocque and first published in 1746. A scanned version of this map available from The David Rumsey Map Collection was georeferenced by the Kindred London mapping project. The broad goal of the Kindred London project is to create four digitized road networks from four historic maps of London that will be used for an online, interactive web platform that will allow users to experience what it would have been like to travel the streets of London.

  16. Title: Road Network, London, 1746

    Contributors:

    Summary: This line shapefile contains the road network digitized from a map entitled "Composite Map: (Facsimile) Rocque's Map of London. 1746." Published in 1919, this composite map is considered one of the best facsimiles of the original Rocque Map ("A plan of the cities of London and Westminster, and borough of Southwark"), created by John Rocque and first published in 1746. A scanned version of this map available from The David Rumsey Map Collection was georeferenced by the Kindred London mapping project. Segments of roads, paths, bridges, tunnels, water crossings, and stairs, were digitized using route name and type, traffic volume, and access. The broad goal of the Kindred London project is to create four digitized road networks from four historic maps of London that will be used for an online, interactive web platform that will allow users to experience what it would have been like to travel the streets of London. Kindred London Mapping Project. (2017). Road Network, London, 1746. Center for Spatial and Textual Analysis, Stanford University. Available at: http://purl.stanford.edu/wx413hq1837. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  17. Title: Scotland burghs and districts, 1961

    Contributors:

    Summary: These are digital boundaries for the system of burghs and districts of county essentially created by the Local Government (Scotland) Act 1929 and continuing to exist until 1975. Scotland was divided into Cities, Large Burghs, Small Burghs and Districts of County (with the exception of the counties of Kinross and Nairn, whose rural areas were not subdivided). These units generally functioned as sub-divisions of Scottish Counties with powers varying according to status, but the four Cities had full independence from the County they were situated within. This file represents the system as it was used to report the 1961 Census of Population.
