BLM Alaska PLSS Intersected: This dataset represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. The data has been converted from source documents to digital form and transferred into a GIS format that is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data is optimized for data publication and sharing rather than for specific "production" or operation and maintenance. This data set includes the following: PLSS Fully Intersected (all of the PLSS feature at the atomic or smallest polygon level), PLSS Townships, First Divisions and Second Divisions (the hierarchical break down of the PLSS Rectangular surveys) PLSS Special surveys (non rectangular components of the PLSS) Meandered Water, Corners and Conflicted Areas (known areas of gaps or overlaps between Townships or state boundaries). The Entity-Attribute section of this metadata describes these components in greater detail.

Administered Lands is a BLM Alaska GIS dataset that combines publicly available borough, municipality, state, federal, and other entity management and ownership GIS data. This is the basis for BLM’s national Surface Management Agency GIS dataset that was developed to fulfill the public and Government’s need to know what agency is managing Federal land in a given area. This data set is comprised of various sources of geospatial information that have been acquired from local, state and federal agencies in order to assemble a comprehensive representation of current land surface manager. There are many land managing agencies and branches of government and this dataset attempts to classify these entities into general categories. This data does not demonstrate or infer land ownership. The business need for this data includes, but is not limited to, land use planning, permitting, recreation, and emergency response. Due to the nature of assembling geospatial information from multiple sources, integration of features into a single layer may introduce inaccurate artifacts. Acquired datasets have been cross-walked to a standardized schema to aid in the depiction of land surface manager across the state of Alaska. This dataset will contain errors. For the most up to date and accurate information, please contact the surface manager agency for the area in which you are interested.

In support of the proposed Susitna-Watana Hydroelectric Project, the Alaska Division of Geological & Geophysical Surveys (DGGS) developed a Geographic Information System (GIS)-based geologic compilation of published and unpublished maps for twelve, inch-to-mile (1:63,360-scale) quadrangles encompassing the proposed hydroelectric project footprint, including the anticipated reservoir and surrounding area. DGGS geologists reviewed and analyzed existing geologic mapping for quality and completeness, and the maps were converted for use in GIS. The conversion process included scanning and georeferencing the original hard-copy map documents, creating a geodatabase, digitizing the geologic data, assigning attributes, and producing a digital data product for public release. The best available geologic mapping was synthesized into a single compilation data layer, and is packaged along with georeferenced scans and digitized vector files of the original geologic source maps. Bedrock geology was reviewed and revised by an independent contractor to ensure consistency with current geologic interpretations of the area. This geodatabase product will be a valuable reference resource for developers, planners, and scientists working on the hydroelectric project, as well as for any other projects in the area.

Lands approved or conveyed to the State of Alaska for a variety of reasons such as general purpose, expansion of communities, University of Alaska, and recreation.

This shape file characterizes the geographic representation of land parcels within the State of Alaska contained by the Ownership - State Owned, Managed - State Tentatively Approved or Patented category. It has been extracted from data sets used to produce the State status plats. This data set includes cases noted on the digital status plats up to one day prior to data extraction.

Each feature has an associated attribute record, including a Land Administration System (LAS) file-type and file-number which serves as an index to related LAS case-file information. Additional LAS case-file and customer information may be obtained at: http://dnr.alaska.gov/projects/las/ Those requiring more information regarding State land records should contact the Alaska Department of Natural Resources Public Information Center directly.

This data set includes ArcInfo-formatted maps of the Kuparuk River Basin Region of the Alaskan North Slope (at 1:250,000 scale) and five subset study areas: the Upper Kuparuk River Basin Subregion (1:25,000), the Imnavait Creek Landscape (1:6,000), the Toolik Lake Landscape (1:5,000), the Imnavait Creek Grid (1:500), and the Toolik Lake Grid (1:500). Land cover (satellite-derived) and elevation data (United States Geological Survey digital elevation model (USGS DEM-derived)) are provided for the Kuparuk River Basin Region. For the five subset areas, an integrated terrain unit mapping (ITUM) approach simultaneously mapped vegetation and other terrain features as interpreted in the field from a common aerial-photograph base. The result is a single ITUM map for each area, including vegetation, geomorphology, glacial geology, and many other features. Various supplemental maps (e.g., hydrologic features and roads) for each of the areas are available for use as overlays. Data is only available as a single tar.gz file containing all of the files.

The Geospatial Fabric for National Hydrologic Modeling (Viger and Bock, 2014; Bock and others, 2021) is a dataset of hydrographic features and spatial data for use within the National Hydrologic Model that covers the conterminous United States (CONUS), Hawaii, and most major river basins that flow in from Canada. This U.S. Geological Survey (USGS) data release consists of the geospatial fabric features and other related spatial datasets created to expand the National Hydrologic Model to Alaska. The National Hydrologic Model database contains parameters for hydrologic response units (HRUs) and stream segments needed to run the NHM. These parameters are generated using python scripts to process input datasets such as digital elevation models, soil maps, and land cover classifications. Many of the parameters were left at their default model value as they would need to be calibrated as part of the PRMS model development process. Please refer to the Supplemental Information and the P ...
