  5. Title: EPA 2014 Toxics Release Inventory - Oregon

    Contributors:

    Summary: The Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. Certain industrial facilities in the U.S. must report annually how much of each chemical is recycled, combusted for energy recovery, treated for destruction, and disposed of or otherwise released on- and off-site. This information is collectively referred to as production-related waste managed. This shapefile represent releases of TRI-covered chemicals to the environment in Oregon. A "release" of a chemical means that it is emitted to the air or water, placed in some type of land disposal, or transferred off-site for disposal or release.

  12. Title: MassGIS 2003 Massachusetts Protected and Recreational Open Space (Region Polygons) (March 2003)

    Contributors:

    Summary: This protected and recreational open space datalayer contains polygon regions representing the boundaries of conservation lands and outdoor recreational facilities in Massachusetts. Regions are classified by site name so that multiple adjacent parcels with identical property names are grouped together as a site. This is useful for linking annotation and SCCRP information to sites. The region attribute table contains a subset of the fields in the polygon attribute table including SITE_NAME, SCORP_ID, FEE_OWNER, SYMOP1, and a field called REGION-ID used for linking to annotation. Conservation and outdoor recreation facilities owned by federal, state, county, municipal, and nonprofit enterprises are included in this datalayer. Privately owned lands with deeded restrictions are also included, as are lands in the Chapter 61 program. This datalayer can also be linked, through related tables, with the 1988 Statewide Comprehensive Outdoor Recreation Plan (SCORP) inventory, with facilities and activities data for recreation sites. The datalayer is paneled into 351 town coverages and significant updates are ongoing. This update effort, coordinated by MassGIS, uses volunteers from state environmental agencies, regional planning commissions, local watershed associations, town conservation commissions, municipal planning and engineering departments, local and regional nonprofits, and open space plan committees. Although the initial data collection effort for this data layer has been completed, open space changes continually and this data layer is therefore considered to be under development. Additionally, due to the collaborative nature of this data collection effort, the accuracy and completeness of open space data varies across the state's municipalities. Attributes, while comprehensive in scope, may be incomplete for many parcels. The following types of land are included in this 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 Food and Agriculture (DFA) Aquifer protection land - not zoning overlay districts Watershed protection land - not zoning overlay districts Cemeteries - if they are a recognized conservation or recreation resource Also included for some towns are lands in the Chapter 61 program (61 = Forestry; 61A = Agriculture; 61B = Recreation). These parcel boundaries are not currently available state-wide, and may not be maintained over time, but can be useful for municipal planning purposes.

  13. Title: MassGIS 2003 Massachusetts National Wetlands Inventory (Polygons) (February 2003)

    Contributors:

    Summary: This layer contains polygon features representing various wetlands and deepwater habitats for the state for Massachusetts. The National Wetlands Inventory (NWI) project, administered by the U.S. Fish and Wildlife Service, was established to generate information about the characteristics, extent and status of the Nation's wetlands and deepwater habitats. This information is used by Federal, State, and local agencies, academic institutions, U.S. Congress, and the private sector. The Emergency Wetland Resources Act of 1986 directs the Service to map the wetlands of the United States. The NWI has mapped 89% of the lower 48 states, and 31% of Alaska. The Act also requires the Service to produce a digital wetlands database for the United States. About 39% of the lower 48 states and 11% of Alaska are digitized. Approximately 50 percent of Massachusetts is available in digital format. For full details on the national mapping project visit the National Wetlands Inventory web site: http://www.fws.gov/nwi/

  14. 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.

  16. Title: MassGIS 2003 Massachusetts MHD Routemarker Locations (December 2002)

    Contributors:

    Summary: This datalayer is a point coverage that may be used for plotting route shields that have the look of those on actual highway signs (i.e. red, white and blue Interstate; U.S. shields; boxes for State routes). The layer is intended to be used in conjuction with other Massachusetts Highway Department (MHD) datalayers. Please note that the locations of these points have been chosen to optimize display and do not represent actual roadside locations of route signs.

  18. Title: MassGIS 2003 Massachusetts Designated Shellfish Growing Areas (Polygons) (October 2000)

    Contributors:

    Summary: The Designated Shellfish Growing Area (DSGA) datalayer was compiled by the Department of Fisheries, Wildlife and Environmental Law Enforcement's (DFWELE) Division of Marine Fisheries (DMF). Three hundred and three growing areas in Massachusetts have been designated by DMF's Shellfish Project. The data are stored in two feature layers: Designated Shellfish Growing Areas (Arcs) and Designated Shellfish Growing Areas (Polygons). A designated shellfish growing area is an area of potential shellfish habitat, and all three hundred and three DSGA's make up the territorial waters (tidal zone out to the territorial line) of the Commonwealth. Growing areas are managed with respect to shellfish harvest for direct human consumption, and comprise at least one or more classification areas. The classification areas are the management units, and range from being approved to prohibited (six different classification types in all) with respect to shellfish harvest. For example, one growing area may be composed of four classification areas, all of which are managed separately (have a classification type the same or different from the rest in the growing area). This coverage reflects classification areas as of July 1, 2000. The dataset was originally issued in October 2000.

  19. Title: MassGIS 2003 Massachusetts NHESP Priority Sites of Rare Species Habitats & Exemplary Natural Communities (June 1999)

    Contributors:

    Summary: The Priority Habitats of Rare Species datalayer consists of polygons that represent estimations of important state-listed rare species habitats in Massachusetts. These habitats are based on rare species population records maintained in the Natural Heritage & Endangered Species Program (NHESP) database. The polygons are spatially represented at 1:25000 or 1:24000 on the Program's series of USGS topographic maps. Program scientists draw approximate habitats by analyzing population records, species habitat requirements, and available information about the landscape (particularly from topographic maps and aerial photographs). Most habitat sites are not visited prior to the drawing of these habitats. These polygons are NOT equivalent to 'significant habitat' as may be designated according to the regulations of the Massachusetts Endangered Species Act (MESA). Priority habitats are not protected under the Massachusetts Endangered Species Act, but the rare species that use the habitats are protected by that law.

  20. Title: MassGIS 2003 Massachusetts NHESP BioMap Supporting Natural Landscape (July 2001)

    Contributors:

    Summary: Supporting Natural Landscape is one of two datalayers resulting from the BioMap biodiversity mapping project (also see the NHESP BioMap Core Habitat datalayer description). The Supporting Natural Landscape buffers and connects Core Habitat polygons, which depict the most viable habitat for rare species and natural communities in Massachusetts, and identifies large, naturally vegetated blocks that are relatively free from the impact of roads and other development. The quality of undeveloped land considered in the landscape analysis was evaluated based on four major components: natural vegetation patch characteristics; size of relatively roadless areas; subwatershed integrity; and contribution to buffering BioMap Core Habitat polygons for plants and exemplary communities. These components were represented in seven Factor Maps in 30-meter x 30-meter raster datasets: size of natural vegetation patch; distance from development; forest history; size of individual roadless blocks; size of aggregated roadless blocks; subwatershed integrity; and distance to BioMap Core Habitat. A weighted overlay was performed on these Factor Maps using the Model Builder extension of Spatial Analyst in ArcView 3.2a to produce the Supporting Natural Landscape datalayer.
