Alaska's commercial fisheries are managed using various regulatory areas (i.e., districts and sections). This file geodatabase contains feature class data set that define the current valid districts, sections, and stat areas that may be used in commercial salmon fisheries in 2020. This data set should NOT be used for navigation or for determining compliance with ADF&G Commercial Fishing Regulations. Please consult the ADF&G Salmon Commercial Fisheries Regulations for the official definitions of regulatory boundaries. NOTE: These data attempt to depict boundaries as used for management during a specific time period. In some cases, boundaries used in practice may differ from those described in regulations, reports, maps, and other aids.

New Polling Districts from May 2016. To show the extent of polling districts in City of Bristol and identify each by Ward and by polling district name. Polling districts are Wards that have been sub-divided into districts.

From the site: “The Geologic Atlas of the United States is a set of 227 folios published by the U.S. Geological Survey between 1894 and 1945. Each folio includes both topographic and geologic maps for each quad represented in that folio, as well as description of the basic and economic geology of the area. The Geologic Atlas collection is maintained by the Map & GIS Library. The repository interface with integrated Yahoo! Maps was developed by the Digital Initiatives -- Research & Technology group within the TAMU Libraries using the Manakin interface framework on top of the DSpace digital repository software. Additional files of each map are available for download for use in GIS or Google Earth. A tutorial is provided which describes how to download theses files.”

Map showing Bristol City Centre Evacuation Zones.

Local Authorities have been asked to prepare evacuation plans for city centres following the 9/11 bombing. The evacuation of the whole city centre is extreamly unlikely (except in case of nuclear incident), but occasionally particular zones may need to be evacuated due to threats from flooding, terrorism etc.

The zones are the result of discussions between Bristol City Council and the emergency services, which has simplified the evacuation zones from the previous 32 to 4 and provide mapping information to the city centre evacuation plan.

It forms an important part of the city alert scheme where business have signed up to be warned of emergencies and incidents and can view the map if they are instructed to evacuate from one zone to another.

This digital data set includes vegetation cover classification derived from Landsat MSS data and can be keyed on a 1:250,000 quadrangle basis. Spatial referencing is by 50 meter grid cell size. The data source is Landsat MSS data (73 records), storage required varies by storage medium and selected area. The file structure is sequential. Data are available on: 9-track, 800 bpi, 1600 bpi, 6250 bpi, unlabeled, unblocked, fixed record length tape and 8' floppy disk. Subsets and custom formats are available; documentation is also available. The data is organized by 7 1/2 ' or 15 ' quads. General area covered: Bristol Bay region in Alaska.

This map is for viewing city council districts as well as properties and building footprints owned by the City of Bristol Tennessee.

The Soils datalayer has been automated from published soils surveys as provided on various media by the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS). All soils data released by MassGIS have been "SSURGO-certified," which means they have been reviewed and approved by the NRCS and meet all standards and requirements for inclusion in the national release of county-level digital soils data. Soil survey areas are roughly based on county boundaries.

The SSURGO-certified soils dataset is generally the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. The data include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. Data for survey areas were developed using various scale base maps: some areas at a 1:25,000 or 1:12,000 scale, or at larger scales where source materials (e.g. 1:5,000 MassGIS ortho imagery) were available. Details for a specific survey area are provided in the NRCS-produced metadata that are distributed with the spatial data.

The soil map units are linked to attributes in the National Soil Information System (NASIS) relational database, which gives the proportionate extent of the component soils and their properties.

At MassGIS the soils datalayer is stored in ArcSDE for Oracle as the statewide feature class SOILS_POLY. Two companion layers, SOILSPOT_PT and SOILSPOT_ARC, represent "special" or "ad hoc" features such as gravel pits, wet areas, bedrock escarpments and others. These layers display the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management.

The status for each survey area is stored in the statewide layer named SOILSTAT_POLY. See details in the Entity Attributes section.

The soils polygons were updated in August 2010 for new data for Plymouth. Also, the adjacent survey areas (Barnstable, Bristol North, Bristol South, and Norfolk-Suffolk) were replaced, as these were edited to edge-match with Plymouth. With the August 2010 update, soils data are available for all survey areas in the state except for Franklin, which is under development.

Land Cover Map is a UK Centre for Ecology and Hydrology (UKCEH) spatial dataset, which NRW acquires under licence. There are two datasets that NRW get from UKCEH, these being Land Cover Map 2000 and Land Cover Map 2007. NRW only has a segment of the data and not the whole of GB. This segment covers, the whole of Wales, cross boarder catchments and coastal areas around the Bristol Channel. Land Cover Map 2000 (LCM2000) updates and substantially upgrade UKCEH's Land Cover Map of Great Britain (LCMGB) 1990 and also cover Northern Ireland. This was the first UKCEH all UK dataset. LCM200 was classified in relation to JNCC's Broad Habitats, and so encompasses the entire range of UK Habitats. LCM2000 is used for a wide range of applications including environmental character assessments, environmental protection, transport planning, animal disease distribution, bird and habitat relationships and forestry research. Land Cover Map 2007 (LMC2007) was released in July 2011, and is a parcel-based classification of UK land cover. LCM2007 builds upon the successes of the parcel-based mapping of LMC2000 and employs similar but enhanced classification techniques.

The Air Quality Management Area for BristolThe air quality management area in Bristol has been declared due to exceedances of Nitrogen Dioxide annual and hourly objectives and as a precautionary measure, exceedances of objectives for particulate matter (PM10).Compliance with requirements of Local Air Quality Management Regulations and the National Air Quality Strategy.

We refined a suite of hydrodynamic and individual-based models to understand how climate change may impact red king crab (Paralithodes camtschaticus) recruitment in Bristol Bay, Alaska. We coupled a biophysical individual-based model (IBM) and a Regional Ocean Modeling System (ROMS) circulation model to estimate connectivity between the location of red king crab larval release and benthic settlement location in the eastern Bering Sea including Bristol Bay. We conducted ROMS hindcasts for two representative years: 1999 (cold) and 2005 (warm), and a forecast for a predicted warm year: 2037. Scientific output includes ROMS model files, IBM data files, and a red king crab habitat map. Data for each habitat sample used to qualify habitat type and definitions of habitat type is included in the “Habitat Data File” folder. Data for the habitat map were divided into physical (sediments, rocks, and shells) and biological (epibenthos) categories using various data sources including published and unpublished digital data, paper data sheets, and cruise logbooks. Each location in the habitat database was assigned to a cell of the habitat grid, and each cell was then classified as good habitat or bad habitat. Cells containing both good and bad habitat were classified as good habitat, while cells in the grid containing no samples were classified as unknown habitat. The “Connectivity Zones”, “Habitat Grid”, and “Habitat Map” folders contain ArcMap shape files for the habitat map grid, habitat type designations within the grid, connectivity zones, and images of the habitat map. The grid for the habitat information had a cell size of 37 km x 37 km. The ROMS grid used for the circulation model was too finely-divided (2 km x 2 km) for the scale of the habitat data; however, the habitat grid was based on a regularized version of the ROMS grid. The connectivity grid of polygons (“zones”) of various shapes and sizes was assembled to quantify rates of connectivity and retention in areas of interest.
