  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.

  9. Title: MassGIS 2003 Massachusetts bicycle trails (January 2003)

    Contributors:

    Summary: This dataset, formerly named 'Rail Trails,' was created by the Massachusetts Department of Environmental Management for the purpose of regional planning and mapping. In 2002 the layer was updated and renamed 'Bicycle Trails'. The linework in this layer represents trails which all permit bicycle travel or corridors with conversion potential; however, bicycles are not the exclusive travel mode permitted on these trails. The manager or owner of the trail should be contacted for detailed information about the permitted uses and rules of conduct that are specific to that trail. Most such corridors use, or connect to, old railway lines. Many of the trails represented in this layer are open to some combination of activities such as walking, jogging, rollerblading, skiing, horse riding, snowmobiling, etc., as well as bicycling.

  10. Title: Average Annual Precipitation, New York State, 1961-1990

    Contributors:

    Summary: This data set shows polygons of average annual precipitation in New York State, for the climatological period 1961-1990. Parameter-elevation Regressions on Independent Slopes Model (PRISM) derived raster data is the underlying data set from which the polygons and vectors were created. PRISM is an analytical model that uses point data and a digital elevation model (DEM) to generate gridded estimates of annual, monthly and event-based climatic parameters. These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the Spatial Climate Analysis Service, the USDA - NRCS National Water and Climate Center, the USDA - NRCS National Cartography and Geospatial Center, or the U.S. Geological Survey in the use of these data.

  15. Title: Massachusetts Median Home Sales Price, 1994-1995

    Contributors:

    Summary: This datalayer displays a polygon coverage of Massachusetts town boundaries with associated attribute data on median home sales price changes for the years 1994 and 1995 for all towns except Buckland, Gosnold, Monroe, and Nantucket. These data exclude all condominium sales. Recovery in home sale prices since the last recession has been dramatically uneven among communities in the region. Prices have increased in high priced areas, while prices are still below their 1990 levels in low priced areas. 'Trade-up' homeowners from the large generation of baby-boomers are driving prices higher in more expensive communities, while demand continues to lag in the lower cost communities. This price differential may decline as the much smaller post-baby-boomer generation enters its prime home-buying years. Average home sale price for towns in the Metropolitan Area Planning Council region are provided for 1994 and 1995.
