Tribal Census Tracts

Tribal Census Tracts This feature layer, utilizing National Geospatial Data Asset (NGDA) data from the U.S. Census Bureau (USCB), depicts American Indian tribal census tracts. Per the [USCB], “a tribal census tract is a relatively permanent statistical subdivision of a federally recognized American Indian reservation and/or off-reservation trust land, delineated by the American Indian tribal government and/or the Census Bureau for the purpose of presenting demographic data. For federally recognized American Indian Tribes with reservations and/or off-reservation trust lands with a population less than 2,400, a single tribal census tract is defined. Qualifying areas with a population greater than 2,400 could define additional tribal census tracts within their area."

TNF Mean High Water Sync Enabled

This dataset contains MHW vector shorelines that were developed using a protocol for creating a continuous shoreline based on NOAA MHW National Shoreline and CUSP datasets. In this protocol, NOAA data is considered “the best data source”. Where it exists, NOAA MHW data is used. If multiple NOAA maps exist for the same area, the most recent data is typically used. Where NOAA data is absent, the “next-best” available MHW shoreline is used and sometimes generated via digitizing from high-resolution orthoimagery. The source data for every arc in the continuous shoreline is recorded in the attribute table. Because the MHW line originates from a variety of source data, the dataset is titled “mean high water, combined source" (MHW_CS). It is also referred to as the "best available" shoreline dataset as it seeks to integrate data with an authoritative pedigree, as well as data with highest available spatial accuracy. Update 11/16/2023: MHW shoreline vectors derived from modern, high quality lidar (~2012 and later) using NOAA Vdatum software are currently considered the best available source. These lidar-derived shorelines, whether produced by NOAA, the USFS, or other entities, now take precedence over other datasets unless a review reveals shoreline vectors from an alternative source are more accurate. CAUTION: DO NOT RELY ON THE ATTRIBUTE TABLE FOR ANALYSIS! MHW_CS contains the latest MHW shoreline linework updates available as of October, 2024. The linework is being made available for use; HOWEVER, the attribute table is still undergoing updates. The attribute table schema is not expected to change, but attribute fields are still being populated, edited for consistency, and undergoing a general QA/QC. In particular, the values in the field labeled "Attribute" need updating for a large portion of the dataset. This metadata document will be updated once the attribute table edits are complete. Update 12/16/2025: Wrangell Island is updated with the latest lidar- and Vdatum-derived MHW shoreline. The attribute table is accurate for the Wrangell Island lines added in this update.
FWS National Regional Boundaries

This data set delineates the boundaries of the U.S. Fish and Wildlife Service geographic Regions. The dataset was created as a geographic representation of the Regional administrative boundaries of the US Fish and Wildlife Service at a very coarse scale. The boundaries were created using the ArcGIS shoreline dataset from approximately 1995. This dataset should not be used for legal purposes or at small scales and does not accurately denote the shorelines of the united states. The Regional Boundaries data set is managed by the FWS Headquarters, Joint Administrative Operations (JAO), Branch of Geospatial Data Services (BGDS). The complete data and metadata can be accessed here: https://catalog.data.gov/dataset/us-fish-and-wildlife-service-regional-boundaries. This data set is a graphical representation and has limitations of accuracy as determined by, among others, the source, scale and resolution of the data. Kentucky Bend was added to R4 - Southeast Region and was the most recent modification to this dataset, completed on 2/3/2026 ServCat Repository: [https://iris.fws.gov/APPS/ServCat/Reference/Profile/52322] Point of Contact: [Matthew_bobo@fws.gov] e-mail: [fwsgis@fws.gov] DOI Interior Regions / Regional Boundaries (https://fws.maps.arcgis.com/home/item.html?id=309aa728d6c041ceaefc1526a409b5d1).
Lease Sale Tract Current

The lease sale tract represents the lands the Division of Oil and Gas is committed to adjudicating prior to a lease. A lease sale tract is not an authorization. A lease may be awarded after a responsive bid on a lease sale tract is accepted and the lease is adjudicated. Inclusion of land within a lease sale tract does not guarantee the State of Alaska owns the oil, gas, or geothermal resource on all lands within the tract. In addition, part or all of the State-owned land may have a lease in effect, either issued or on appeal. The source and official record are LAS case files available [here]. The codes and descriptions contained in this dataset are available from the Division of Oil and Gas.
Federal Housing Administration Single-Family – Properties for Sale

Federal Housing Administration Single-Family – Properties for Sale This National Geospatial Data Asset (NGDA) dataset, shared as a Federal Housing Administration feature layer, displays single-family real estate owned (REO) properties that are up for sale in the United States. Per [Housing and Urban Development (HUD)], "The U.S. Department of Housing and Urban Development's Real Estate Owned (REO) properties are a result of the Federal Housing Administration (FHA) paying a claim to a lending institution on a foreclosed property which was financed with an FHA Insured Mortgage and the lender transferring ownership of the property to HUD. Typically, title to the property is not transferred (or the claim paid) until the previous owner is evicted from the property. Normally, after the home is transferred to HUD, the property will go up for auction on the HUD Home store website."

Tongass National Forest Phased Implementation

This dataset contains polygons which represent areas of forest divided into Phases (1, 2, or 3) that establish boundaries within the Timber Sale Program Adaptive Management Strategy on the Tongass National Forest. Phase 1 - This includes most of the roaded portion of the ASQ land base, along with most of the lower value inventoried roadless areas. This portion of the land base could sustain a level of timber harvest of about 150 MMBF. Phase 2 - This includes Phase 1 lands and most of the moderate value roadless areas. The Phase 2 portion of the ASQ land base could sustain a level of timber harvest of about 200 MMBF. Phase 3 includes the remaining ASQ land base.
Tongass National Forest Past Harvest from CoverType

For detailed information on how to query this data set and how layer file user views were derived go to Resource Details section in metadata for this file.CoverType is used to stratify the Tongass N.F. according to forest cover type. CoverType is a photo-interpreted delineation of the Tongass National Forest by land type and timber cover type. Classification of lands was done sequentially: 1) land and water identified; 2) forested and non-forested areas were identified; 3) forested areas were classified by forest type and forest productivity; and 4) productive forest lands were further characterized by volume class, tree size, species composition. The original classifications were based on photo-interpretation of 1:15840 aerial photographs in 1978. The minimum map unit size is approximately 10 acres, though the average area for forested polygons is 60 acres. Additionally, CoverType is updated for new stands created through natural events or management activity. The data has also been corrected for errors, as found, that occurred during the attributing and digitizing of the original classification data. Data has been compiled for some lands in southeast Alaska outside National Forest System Ownership. Data collected outside NFS boundaries has been inconsistently collected and compiled and should not be used for data analysis..
