This data depicts railroad locations (1:63,360) in Alaska as digitized primarily from 1:24,000, 1:63,360, and 1:250,000 USGS quadrangles. The source document that represented the newest information and best geographic location was used to capture the data. All infrastructure from the primary source document was digitized and then supplemented with the information from other source documents for additional or updated infrastructure or attributes.

Each community in the study area is served by an isolated grid, with its own generation and distribution infrastructure. All energy infrastructure in each community is within the community’s footprint. Barrow and Prudhoe Bay, the two largest population centers, rely completely on natural gas for generation of electricity. Nuiqsut relies both on natural gas and diesel. Other than Barrow and Prudhoe Bay, all other communities have small demand loads, and thus only generate less than a megawatt.
Some of the CYR rasters intentionally do not align or have the same extent. These rasters were not snapped to a common raster per the authors' discretion. Please review selected rasters prior to use. These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - An aboveground live forest biomass map for the conterminous U.S., Alaska and Puerto Rico is derived from modeling field biomass estimates, collected nationwide by the USDA Forest Service Forest Inventory and Analysis (FIA) program, as functions of 250-m resolution satellite image products and other digital geographic layers....
This EnviroAtlas web service supports research and online mapping activities related to EnviroAtlas (https://www.epa.gov/enviroatlas). The Clean and Plentiful Water category in this web service includes layers illustrating the ecosystems and natural resources that filter and regulate water, the need or demand for clean and plentiful water, the impacts associated with water quality, and factors that place stress on water quality and supply. EnviroAtlas allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the conterminous United States. Additional descriptive information about each attribute in this web service is located within each web...
This EnviroAtlas web service supports research and online mapping activities related to EnviroAtlas (https://www.epa.gov/enviroatlas). The Food, Fuel, and Materials category in this web service includes layers illustrating the ecosystems and natural resources that provide or support the production of food, fuel, or other materials, the need or demand for these items, the impacts associated with their presence and accessibility, and factors that place stress on the natural environment's capability to provide these benefits. EnviroAtlas allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the conterminous United States.

This data depicts electrical power line locations in Alaska as digitized primarily from 1:24,000, 1:63,360, and 1:250,000 USGS quadrangles. The source document that represented the newest information and best geographic location was used to capture the data. All infrastructure from the primary source document was digitized and then supplemented with the information from other source documents for additional or updated infrastructure or attributes.
Utility lines were merged from various sources to provide the best comprehensive coverage of the Northwest Boreal LCC. This data depicts the spatial extent of electrical powerlines in the Central Yukon study area. Electrical lines, telephone lines, and pipelines were provided by Alaska Department of Natural Resources. The original statewide data was digitized from 1:63,360 and 1:250,000 USGS topographic maps. The source document that represented the newest information and best geographic location was used to capture the data. All infrastructure from the primary source document was digitized and then supplemented with the information from other source documents for additional or updated infrastructure or attributes.
The use of scenarios was identified by the NSSI Oversight Group as a potentially important tool in helping identify future research and monitoring needs. Scenarios can provide a means to identify a plausible range of pathways by which an uncertain future may unfold. In that way, they can then be used to help guide agency considerations for how to effectively target research and monitoring efforts in a manner that will be most useful for resource management decision-making under uncertain future conditions. A collaboration to undertake that scenarios project was formed between NSSI, the University of Alaska Fairbanks, and GeoAdaptive, LLC, an internationally experienced geospatial scenarios consultant. This dataset...
This dataset depicts wind energy priority areas developed by the BLM in Utah. This dataset was received from BLM without metadata.
Powerlines in the western United States. Data was obtained from the ICEBMP existing utility corridors data set.
Annual average wind resource potential of California at a 50 meter height.

This data depicts locations of oil wells on the North Slope. The original data was created by the Alaska Oil and Gas Conservation Commission. Audobon Alaska provided the data as a spatial feature class to Alaska Natural Heritage Program.
Average electrical generation of coal, gas turbine, utility hydroelectric, wind, and diesel sites in Alaska.
Average electrical generation of coal, gas turbine, utility hydroelectric, wind, and diesel sites in Alaska.
Proposed and existing solar and wind project site data which was constructed in GIS at the California State BLM Office, using hardcopy legal information and/or maps obtained from the various field offices in California. The hardcopy information to backup the legal boundaries shown in GIS are stored at the California BLM State Office.
Powerlines in the western United States and Canada as identified by the 22 source data layers used to compile this shapefile. Source data were collected by personal contact or through the internet in the winter and spring of 2004 and assimilated using ArcGIS. This file is a complete record of overhead powerline data that was avaliable as of 5/15/2004 but IS NOT INTENDED TO BE A COMPLETE REPRESENTATION OF THE SUM TOTAL OF ALL POWERLINES ON THE GROUND. These data primarily depict the higher voltage, long distance transmission lines but some arcs likely represent lower voltage distribution lines.
