This is the web map that is used in the U.S. Fish &Wildlife Service's Alaska Region online portal for 1:30,000 scale geoPDF topographic maps of the National Wildlife Refuges within the state of Alaska.The maps accessible via the online portal cover 100% of the Alaska National Wildlife Refuges, for a total of 604 maps. Each map covers an area 25 miles east/west by 25 miles north/south, for a total of 625 square miles per map sheet. The maps display land ownership within the Refuges, as well as Refuge and Wilderness boundaries, and towships and ranges (the Public Land Survey System , or PLSS), all overlaid on top of U.S. Geological Survey 1:63,360 scale hillshaded topographic maps.These maps are in the geoPDF format, which is the standard Adobe PDF format, with the addition of geographic referencing information embedded in the file. This allows the user to load the maps into a GPS-enabled mobile device (phone, tablet, etc.) for reference, navigation, and data-recording in the field, without the need for a cell phone connection.

State of Alaska tax parcel data by authoritative data source. This map is for use within the Alaska Geospatial Council Cadastre Technical Working Group's Hub site.

A selection of the General Land Status dataset that reflects National Wildlife Refuge Lands located within a section.This data has been generalized to the section level. For source data, please see the Bureau of Land Management - Alaska Section. Note: This map shows general land ownership information. When reviewing this map, please remember that federal, ANCSA, and state land ownership is depicted, hierarchically, by entire section. For example, any portion of a section (640 acres) falling within State Patented or Tentatively Approved land causes the whole section to be depicted as state land, even if the State Patented or Tentatively Approved land is only a fraction of the section, and federal land and/or ANCSA land also occurs in the section.

The land ownership hierarchy is as follows: 1. State Municipal Entitlements or Land Exchanges or Other Land Disposals. 2. Patented Disposed Federal Lands (Native Allotments or Private Parcels). 3. State Patented or Tentatively Approved or Other State Acquired Lands (includes casetypes 101-114, 116-117, 128-129). 4. Alaska Native Claims Settlement Act (ANCSA) Patented or Interim Conveyed. 5. Major Military. 6. National Wildlife Refuges, National Park System Units. 7. National Wild & Scenic Rivers outside National Park System Units and National Wildlife Refuges. 8. National Forests and Monuments, National Petroleum Reserve-Alaska, National Recreation Areas and National Conservation Areas. 9. Bureau of Land Management Public Lands.

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.

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.

This product is part of the Landscape Change Monitoring System (LCMS) data suite. It shows LCMS modeled change classes for each year. LCMS is a remote sensing-based system for mapping and monitoring landscape change across the United States. Its objective is to develop a consistent approach using the latest technology and advancements in change detection to produce a best available map of landscape change. Because no algorithm performs best in all situations, LCMS uses an ensemble of models as predictors, which improves map accuracy across a range of ecosystems and change processes (Healey et al., 2018). The resulting suite of LCMS change, land cover, and land use maps offer a holistic depiction of landscape change across the United States over the past four decades.Predictor layers for the LCMS model include annual Landsat and Sentinel 2 composites, outputs from the LandTrendr and CCDC change detection algorithms, and terrain information. These components are all accessed and processed using Google Earth Engine (Gorelick et al., 2017). To produce annual composites, the cFmask (Zhu and Woodcock 2012), cloudScore, and TDOM (Chastain et al., 2019) cloud and cloud shadow masking methods are applied to Landsat Tier 1 and Sentinel 2a and 2b Level-1C top of atmosphere reflectance data. The annual medoid is then computed to summarize each year into a single composite. The composite time series is temporally segmented using LandTrendr (Kennedy et al., 2010; Kennedy et al., 2018; Cohen et al., 2018). All cloud and cloud shadow free values are also temporally segmented using the CCDC algorithm (Zhu and Woodcock, 2014). The raw composite values, LandTrendr fitted values, pair-wise differences, segment duration, change magnitude, and slope, and CCDC September 1 sine and cosine coefficients (first 3 harmonics), fitted values, and pairwise differences, along with elevation, slope, sine of aspect, cosine of aspect, and topographic position indices (Weiss, 2001) from the National Elevation Dataset (NED), are used as independent predictor variables in a Random Forest (Breiman, 2001) model. Reference data are collected using TimeSync, a web-based tool that helps analysts visualize and interpret the Landsat data record from 1984-present (Cohen et al., 2010).Outputs fall into three categories: change, land cover, and land use. Change relates specifically to vegetation cover and includes slow loss, fast loss (which also includes hydrologic changes such as inundation or desiccation), and gain. These values are predicted for each year of the Landsat time series and serve as the foundational products for LCMS.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public open space and voluntarily provided, private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastral Theme (http://www.fgdc.gov/ngda-reports/NGDA_Datasets.html). PAD-US is an ongoing project with several published versions of a spatial database of areas dedicated to the preservation of biological diversity, and other natural, recreational or cultural uses, managed for these purposes through legal or other effective means. The geodatabase maps and describes public open space and other protected areas. Most areas are public lands owned in fee; however, long-term easements, leases, and agreements or administrative designations documented in agency management plans may be included. The PAD-US database strives to be a complete “best available” inventory of protected areas (lands and waters) including data provided by managing agencies and organizations. The dataset is built in collaboration with several partners and data providers (http://gapanalysis.usgs.gov/padus/stewards/). See Supplemental Information Section of this metadata record for more information on partnerships and links to major partner organizations. As this dataset is a compilation of many data sets; data completeness, accuracy, and scale may vary. Federal and state data are generally complete, while local government and private protected area coverage is about 50% complete, and depends on data management capacity in the state. For completeness estimates by state: http://www.protectedlands.net/partners. As the federal and state data are reasonably complete; focus is shifting to completing the inventory of local gov and voluntarily provided, private protected areas. The PAD-US geodatabase contains over twenty-five attributes and four feature classes to support data management, queries, web mapping services and analyses: Marine Protected Areas (MPA), Fee, Easements and Combined. The data contained in the MPA Feature class are provided directly by the National Oceanic and Atmospheric Administration (NOAA) Marine Protected Areas Center (MPA, http://marineprotectedareas.noaa.gov ) tracking the National Marine Protected Areas System. The Easements feature class contains data provided directly from the National Conservation Easement Database (NCED, http://conservationeasement.us ) The MPA and Easement feature classes contain some attributes unique to the sole source databases tracking them (e.g. Easement Holder Name from NCED, Protection Level from NOAA MPA Inventory). The "Combined" feature class integrates all fee, easement and MPA features as the best available national inventory of protected areas in the standard PAD-US framework. In addition to geographic boundaries, PAD-US describes the protection mechanism category (e.g. fee, easement, designation, other), owner and managing agency, designation type, unit name, area, public access and state name in a suite of standardized fields. An informative set of references (i.e. Aggregator Source, GIS Source, GIS Source Date) and "local" or source data fields provide a transparent link between standardized PAD-US fields and information from authoritative data sources. The areas in PAD-US are also assigned conservation measures that assess management intent to permanently protect biological diversity: the nationally relevant "GAP Status Code" and global "IUCN Category" standard. A wealth of attributes facilitates a wide variety of data analyses and creates a context for data to be used at local, regional, state, national and international scales. More information about specific updates and changes to this PAD-US version can be found in the Data Quality Information section of this metadata record as well as on the PAD-US website, http://gapanalysis.usgs.gov/padus/data/history/.) Due to the completeness and complexity of these data, it is highly recommended to review the Supplemental Information Section of the metadata record as well as the Data Use Constraints, to better understand data partnerships as well as see tips and ideas of appropriate uses of the data and how to parse out the data that you are looking for. For more information regarding the PAD-US dataset please visit, http://gapanalysis.usgs.gov/padus/.

This layer represents the boundaries for existing and in-progress BLM Land Use Planning Area (LUPA) polygons. Land Use Planning Areas are geographic areas within which the BLM will make decisions during a land use planning effort. Land Use Planning Area Boundaries shift from an "in-progress" status and become Existing Land Use Planning Areas when the Land Use Plan has been approved and a Record of Decision Date has been established.

RS 2477 stands for Revised Statute 2477 from the Mining Act of 1866, which states:

"The right-of-way for the construction of highways over public lands, not reserved for public uses, is hereby granted."

The act granted a public right-of-way across unreserved federal land to guarantee access as land transferred to state or private ownership. Rights-of-way were created and granted under RS 2477 until its repeal in 1976. In Alaska, federal land was "reserved for public uses" in December 1968, with passage of PLO 4582, also known as the "land freeze." This date ends the window of RS 2477 qualification in Alaska.

This service combines parcel data from various local government bodies in Alaska and describes a subset of input fields using consistent field names. This service was designed for use in statewide applications that only require specific types of land parcel information, and benefit from having this information in a single service with a consistent schema. Any changes to input parcel data will trigger this service to update. Note that many input services do not include a truly unique identifier, or sometimes any identifier at all. The 'parcel_id' field contains a record identifier carried over from the input service, or is null if there is none. The 'local_gov' value of any record can be used to reference an input parcel web service in the table below.During processing, a *mostly unique identifier is created, called 'feature_id'. Duplicate values will occur for records that have identical 'local_gov' and 'parcel_id' values and also identical geometries. These cases are extremely rare (< 0.003%), and for the vast majority of records 'feature_id' is unique. Any duplicate values will be attached to parcels in the exact same place.Please reference original parcel web services if your use case requires official, authoritative, or comprehensive land parcel information.

This geospatial dataset provides model-based predictive maps of subsistence land use in rural Interior Alaska. Subsistence harvesting of wild resources is crucial to the well-being of Alaska Natives and rural Alaskans. The development of these community and regional scale maps was intended to improve our understanding of the spatial extent and patterns of subsistence practices, to support communication among land users, and to facilitate predictions of the human impacts from changes in resource availability, climate and environment, land use, and policy. Logistic regression models for predicting subsistence land use were developed using publicly-available maps of documented subsistence use areas assembled by Alaska Department of Fish and Game for 30 communities (Neufeld et al. 2019). Separate models were used for remote communities and road-connected communities. The best-fit models of subsistence land use probability included the terms: distance to community, distance to main travel corridors (rivers for remote communities; roads and rivers for road-connected communities), distance to lakes (for remote communities only), and community population size. The models were applied to 64 rural communities throughout the Interior region to generate probability maps of subsistence land use at the community level (file names: probability_subsistence_*communitytype*_*CommunityName*.tif). A regional probability map of subsistence land use was constructed using the maximum probability value per pixel from community-level maps (file name: probability_subsistence_InteriorAK.tif). Maps of predicted subsistence use areas were created by classifying the community-level probability maps into used and unused areas (file name: classification_subsistence_InteriorAK.zip). Classification accuracy ranged from 83-86%. Results suggest a large spatial extent (353,771 square kilometers (km2)) of subsistence land use in Interior Alaska, comprising ~60% of the region’s land area. These data were produced as part of a study “Geospatial patterns and models of subsistence land use in rural Interior Alaska” by D. R. N. Brown, T. J. Brinkman, G. Neufeld, L. Navarro, C. L. Brown, H. S. Cold, B. L. Woods, and B. L. Ervin published with Ecology and Society (Brown et al., 2022), https://www.ecologyandsociety.org/vol27/iss2/art23/.
