This service depicts National Park Service tract and boundary data that was created by the Land Resources Division. NPS Director's Order #25 states: "Land status maps will be prepared to identify the ownership of the lands within the authorized boundaries of the park unit. These maps, showing ownership and acreage, are the 'official record' of the acreage of Federal and non-federal lands within the park boundaries. While these maps are the official record of the lands and acreage within the unit's authorized boundaries, they are not of survey quality and not intended to be used for survey purposes." As such this data is intended for use as a tool for GIS analysis. It is in no way intended for engineering or legal purposes. The data accuracy is checked against best available sources which may be dated and vary by location. NPS assumes no liability for use of this data. The boundary polygons represent the current legislated boundary of a given NPS unit. NPS does not necessarily have full fee ownership or hold another interest (easement, right of way, etc...) in all parcels contained within this boundary. Equivalently NPS may own or have an interest in parcels outside the legislated boundary of a given unit. In order to obtain complete information about current NPS interests both inside and outside a unit’s legislated boundary tract level polygons are also created by NPS Land Resources Division and should be used in conjunction with this boundary data. To download this data directly from the NPS go to https://irma.nps.gov Property ownership data is compiled from deeds, plats, surveys, and other source data.

Administrative Boundaries of National Park System Units This National Geospatial Data Asset (NGDA) dataset, shared as a U.S. National Park Service (NPS) feature layer, displays National Park Service tract and boundary data that was created by the Land Resources Division. Per NPS, “Boundary polygons have been created by the Lands Resources Program according to the procedures defined in the Lands Acquisition Procedures Manual. Boundaries were created with data provided by Parks, Region, and Program offices. This data includes but is not limited to deeds, legal descriptions, legislation, survey plats, change orders, segment maps, and the ownership databases of the Land Resources Program.”Frederick Douglass and National Capital Parks Data currency: current Federal service (NPS Land Resources Division Boundary and Tract Data Service)NGDAID: 16 (Administrative Boundaries of National Park System Units - National Geospatial Data Asset (NGDA) NPS National Parks Dataset)For more information: Administrative Boundaries of National Park System Units - National Geospatial Data Asset (NGDA) NPS National Parks DatasetFor feedback please contact: Esri_US_Federal_Data@esri.com NGDA Theme Community This data set is part of the NGDA Cadastre Theme Community. Per the Federal Geospatial Data Committee (FGDC), Cadastre is defined as the "past, current, and future rights and interests in real property including the spatial information necessary to describe geographic extents. Rights and interests are benefits or enjoyment in real property that can be conveyed, transferred, or otherwise allocated to another for economic remuneration. Rights and interests are recorded in land record documents. The spatial information necessary to describe geographic extents includes surveys and legal description frameworks such as the Public Land Survey System, as well as parcel-by-parcel surveys and descriptions. Does not include federal government or military facilities." For other NGDA Content: Esri Federal Datasets

Reclassification tables used to assign standardized land cover class names to land cover raster datasets derived from the National Land Cover Dataset (NLCD) or the Coastal Change Analysis Program (CCAP) sources, for all land cover types (Level 1, Level 2, Natural versus Converted, Impervious Surface).

This report documents the acquisition of source data, and calculation of land cover summary statistics datasets for four National Park Service Greater Yellowstone Network park units and six custom areas of analysis: Bighorn Canyon National Recreation Area, Grand Teton National Park, John D. Rockefeller Jr. Memorial Parkway, Yellowstone National Park, and the six custom areas of analysis. The source data and land cover calculations are available for use within the National Park Service (NPS) Inventory and Monitoring Program. Land cover summary statistics datasets can be calculated for all geographic regions within the extent of the NPS; this report includes statistics calculated for the conterminous United States. The land cover summary statistics datasets are calculated from multiple sources, including Multi-Resolution Land Characteristics Consortium products in the National Land Cover Database (NLCD) and the United States Geological Survey’s (USGS) Earth Resources Observation and Science (EROS) Center products in the Land Change Monitoring, Assessment, and Projection (LCMAP) raster dataset. These summary statistics calculate land cover at up to three classification scales: Level 1, modified Anderson Level 2, and Natural versus Converted land cover. The output land cover summary statistics datasets produced here for the four Greater Yellowstone Network park units and six custom areas of analysis utilize the most recent versions of the source datasets (NLCD and LCMAP). These land cover summary statistics datasets are used in the NPS Inventory and Monitoring Program, including the NPS Environmental Settings Monitoring Protocol and may be used by networks and parks for additional efforts.

This map shows the National Park Service (NPS) jurisdictional boundaries in the District of Columbia symbolized by the six administrative NPS administrative units: Chesapeake & Ohio Canal National Historical Park, George Washington Memorial Parkway, National Capital Parks-East, National Mall and Memorial Parks, Rock Creek Park, and White House and President's Park.This web map is used by the InstantApp NCR NPS Land in DC by Administrative Unit Web App.The NPS Land and Jurisdictional data layers represent the land under the jurisdiction of the NPS including which NPS administrative unit manages it. This boundary is equivalent to the type of boundary that is displayed on park brochure maps.These polygons do NOT represent the legal the boundary. For issues regarding land ownership and official boundaries, contact the National Capital Region Land Resources Program Center using the contact form.The National Capital Region NPS jurisdictional boundaries data is available on the National Capital Region NPS OpenData site, along with other NCR-specific NPS datasets. Visit the National Park Service OpenData site for more NPS data or the Integrated Resource Management Application (IRMA) Portal for NPS data, documents, and more.

National parks and other protected areas are important for preserving landscapes and biodiversity worldwide. An essential component of the mission of the United States (U.S.) National Park Service (NPS) requires understanding and maintaining accurate inventories of species on protected lands. We describe a new, national-scale synthesis of amphibian species occurrence in the NPS system. Many park units have a list of amphibian species observed within their borders compiled from various sources and available publicly through the NPSpecies platform. However, many of the observations in NPSpecies remain unverified and the lists are often outdated. We updated the amphibian dataset for each park unit by collating old and new park-level records and had them verified by regional experts. The original version of this dataset contained occurrence records for 292 of the 424 NPS units and includes updated taxonomy, international and state conservation rankings, hyperlinks to a supporting reference for each record, specific notes, and related fields which can be used to better understand and manage amphibian biodiversity within a single park or group of parks. This version of the dataset (Version 1.4) now contains amphibian occurrence records for 336 of the 431 NPS units as of publication in 2024.

These ESRI shape files are of National Park Service tract and boundary data that was created by the Land Resources Division. Tracts are numbered and created by the regional cartographic staff at the Land Resources Program Centers and are associated to the Land Status Maps. This data should be used to display properties that NPS owns and properties that NPS may have some type of interest such as scenic easements or right of ways.

This technical report documents the acquisition of source data, and calculation of land cover summary statistics datasets for ten National Park Service National Capital Region park units and three custom areas of analysis: Catoctin Mountain Park (CATO), Chesapeake & Ohio Canal National Historical Park (CHOH), George Washington Memorial Parkway (GWMP), Harpers Ferry National Historical Park (HAFE), Manassas National Battlefield Park (MANA), Monocacy National Battlefield (MONO), National Capital Parks - East (NACE), Prince William Forest Park (PRWI), Rock Creek Park (ROCR), Wolf Trap National Park for the Performing Arts (WOTR), and the three custom areas of analysis - National Capital Parks - East: Oxon Cove Park, Oxon Hill Farm, Piscataway Park (NCRN_NACE_OXHI_PISC), National Capital Parks - East: Greenbelt Park and Baltimore-Washington Parkway (NCRN_NACE_GREE_BAWA), and National Capital Parks - East: DC and Suitland Parkway (NCRN_NACE_DC_SUIT).

National Park Service BoundariesNPS Director's Order #25 states: "Land status maps will be prepared to identify the ownership of the lands within the authorized boundaries of the park unit. These maps, showing ownership and acreage, are the 'official record' of the acreage of Federal and non-federal lands within the park boundaries. While these maps are the official record of the lands and acreage within the unit's authorized boundaries, they are not of survey quality and not intended to be used for survey purposes." As such this data is intended for use as a tool for GIS analysis. It is in no way intended for engineering or legal purposes. The data accuracy is checked against best available sources which may be dated and vary by location. NPS assumes no liability for use of this data. The boundary polygons LRD creates represent the current legislated boundary of a given NPS unit. NPS does not necessarily have full fee ownership or hold another interest (easement, right of way, etc...) in all parcels contained within this boundary. Equivalently NPS may own or have an interest in parcels outside the legislated boundary of a given unit. In order to obtain complete information about current NPS interests both inside and outside the units legislated boundary, the tracts file created by LRD should be used in conjunction with this boundary file created by LRD.

Park Boundary polygons for Acadia National Park, Maine. Use attributes to distinguish between lands in fee-ownership, lands still to be acquired in fee-ownership in accordance with Public Law 99-420 or Public Law 97-335 (inholdings or acquisition parcels), or conservation easements. Conservation easement lands held by the NPS are still in private ownership and are generally not open to public access; please observe landowner rights. NOTE: for official land status information, please contact the NPS Lands Office. This layer is produced, maintained, and used by Acadia National Park for cartographic purposes because it fits well with other local data. It does not represent an official or surveyed boundary and should not be used for land transaction purposes. Lines representing the current fee-ownership boundary (approximate) for Acadia National Park. USERS PLEASE NOTE: Lines are considered estimates only and should not be used for transactions and/or legal descriptions, only for general depictions of land holdings. This data layer, for cartographic purposes, has been adjusted to match local municipal tax parcel maps which are of varying accuracy and may not match survey information where it exists. Data layers are provided in shapefile format.

Data attributes are a snapshot of the BLM-AK Land Information System Database and are only accurate as that database. Alaska, being a state within the Public Land Survey System (PLSS), describes land to the aliquot part (subsections of larger land plots) where ever possible. Where data is not able to be described with an aliquot part, the data is generalized to the nearest PLSS section (640 acres). Natural boundaries, such as ridge lines and rivers, are examples where aliquot part descriptions can not be used. USS and Rectangular survey data has not been integrated when creating the geospatial depiction from database records. At this time, all positions are as calculated or as derived from township and section protraction.
