U.S. Geological Survey (USGS) Gap Analysis Project (GAP) 20220131 3.0 vector digital data, raster digital data, tabular digital data PAD-US Version 3.0 https://www.usgs.gov/gapanalysis/PAD-US U.S. Geological Survey (USGS) https://doi.org/10.5066/P9KLBB5D https://www.usgs.gov/programs/gap-analysis-project/science/pad-us-statistics https://www.usgs.gov/gapanalysis/PAD-US U.S. Geological Survey, Gap Analysis Project 20220131 3.0 geodatabase https://www.usgs.gov/gapanalysis/PAD-US U.S. Geological Survey https://doi.org/10.5066/P9KLBB5D Spatial analysis and statistical summaries of the Protected Areas Database of the United States (PAD-US) provide land managers and decision makers with a general assessment of management intent for biodiversity protection, natural resource management, and outdoor recreation access across the nation. This data release presents results from statistical summaries of the PAD-US 3.0 protection status (by GAP Status Code) and public access status for various land unit boundaries (Protected Areas Database of the United States 3.0 Vector Analysis and Summary Statistics). Summary statistics are also available to explore and download (Comma-separated Table [CSV], Microsoft Excel Workbook (.xlsx), Portable Document Format [.pdf] Report) from the PAD-US Lands and Inland Water Statistics Dashboard ( https://www.usgs.gov/programs/gap-analysis-project/science/pad-us-statistics ). The vector GIS analysis file, source data used to summarize statistics for areas of interest to stakeholders (National, State, Department of the Interior Region, Congressional District, County, EcoRegions I-IV, Urban Areas, Landscape Conservation Cooperative), and complete Summary Statistics Tabular Data (CSV) are included in this data release. Raster GIS analysis files are also available for combination with other raster data (Protected Areas Database of the United States (PAD-US) 3.0 Raster Analysis). The PAD-US 3.0 Combined Fee, Designation, Easement feature class in the full inventory, with Military Lands and Tribal Areas from the Proclamation and Other Planning Boundaries feature class (Protected Areas Database of the United States (PAD-US) 3.0, https://doi.org/10.5066/P9Q9LQ4B), was modified to prioritize and remove overlapping management designations, limiting overestimation in protection status or public access statistics and to support user needs for vector and raster analysis data. Analysis files in this data release were clipped to the Census State boundary file to define the extent and fill in areas (largely private land) outside the PAD-US, providing a common denominator for statistical summaries. This spatial analysis of the Protected Areas Database of the United States (PAD-US) 3.0 was performed to provide land managers and decision makers with a general summary of management for biodiversity protection, natural resource management, and outdoor recreation access. The full PAD-US inventory is an aggregation of data from managing entities, or best available sources, representing the U.S. protected areas network and contains many overlapping boundaries. The associated vector analysis files were created to remove overlapping features and "flatten" the data to facilitate spatial analysis and the calculation of area statistics in summary reports. The vector analysis files also allow for other applications that require a representation of overall protection status without overlapping designation boundaries. GAP Status Codes and Public Access Categories are used to calculate total acreage, acres by managing agency, and percent protection status or percent access, respectively. Summaries are available to view or download for various units of interest to stakeholders (all U.S. States and Territories, U.S. States, the Contiguous U.S., and by State, Department of the Interior Region, Congressional District, County, EcoRegions I-IV, Landscape Conservation Cooperatives, and Urban Areas) from the PAD-US Lands and Inland Water Statistics Dashboard ( https://www.usgs.gov/programs/gap-analysis-project/science/pad-us-statistics ) and a complete Summary Statistics Table (CSV) is included in this data release.

The Digital Object Identifier https://doi.org/10.5066/P9KLBB5D for PAD-US 3.0 Spatial Analysis and Statistics provides the persistent reference that should be used to obtain the data for use. The U.S. Geological Survey and all contributing data partners shall not be held liable for improper or incorrect use of the data described and (or) contained herein. All information is created with a specific end use or uses in mind. This is especially true for GIS data, which is expensive to produce and must be directed to meet the immediate program needs. These data were created with the expectation that they would be used for other applications; however, inappropriate uses are listed below. This list is in no way exhaustive but should serve as a guide to assess whether a proposed use can or cannot be supported by these data. For many uses, it is unlikely that PAD-US will provide the only data needed, and for uses with a regulatory outcome, authoritative agency data and field surveys should verify the result. PAD-US is recommended for users seeking general information about more than one agency or organization's lands. Users should seek authoritative source data directly to answer questions regarding one agency or those requiring more frequent updates. Ultimately, it will be the responsibility of each data user to determine if these data can answer the question being asked. Furthermore, the database is released on condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from its authorized or unauthorized use. Inappropriate uses include: Using PAD-US for applications or analyses associated with one agency or a particular unit (agencies are always the best and authoritative source of their land data and many publish updates more frequently than PAD-US). Using some data to map small areas, typically requiring mapping resolution at 1:24,000 scale as boundary quality varies by data source (See "State of PAD-US Data" - a graphical summary of estimated inventory completeness, appropriate scale, and update frequency at: https://communities.geoplatform.gov/ngda-govunits/federal-lands-workgroup/) and using aerial photographs or ground surveys in areas where data are incomplete. Combining these data with other data finer than 1:100,000 scale (except for select federal agencies or state lands identified in "State of PAD-US Data") to produce new hybrid maps or answer queries. Generating specific areal measurements from the data finer than the nearest thousand hectares. Representing boundaries as a legal representation for regulation or acquisition. Establishing definite occurrence or non-occurrence of any feature for an exact geographic area. Determining abundance, health, or condition of any feature. Using the data without acquiring and reviewing the metadata. Using Designation Type (Des_Tp) and/or Unit Name (Unit_Nm) to query area (GIS_Acres) for specific designation types or Units in the Vector or Raster Analysis Files as these fields describe the result of the prioritization process to remove overlapping designations. Use the full inventory geodatabase (PAD_US3_0.gdb, doi.org/10.5066/P9Q9LQ4B) for Designation Type (Des_Tp) and/or Unit Name (Unit_Nm) queries to obtain the original boundary area.

Federal data providers reviewed the translation of their spatial data files into the PAD-US schema and the aggregated database, while the PAD-US Team reviewed the final database and each feature class for overall attribute accuracy and consistency. The Spatial Analysis and Statistics Vector Analysis, Raster Analysis, Summary Statistics by GAP Status Code, and Summary Statistics by Public Access Category ( https://www.usgs.gov/programs/gap-analysis-project/science/pad-us-statistics ) have been reviewed internally by the PAD-US Team through both manual and automated processes. Boundary discrepancies (mostly small slivers) between agency data sets and major overlaps associated with fee ownership (mostly between Federal and State lands) in the PAD-US Fee layer of the PAD-US 3.0 geodatabase (PAD_US3_0.gdb) have been identified and are shared with agency data-stewards, who will edit source data files as appropriate and resources allow. Users are encouraged to review topology overlap errors associated with the PAD-US 3.0 Fee Overlap Assessment (Process Step 10, doi.org/10.5066/P9Q9LQ4B) for reference. Duplicates were identified in the PAD_US3_0.gdb, some are legitimate while others are difficult to accurately assess and remove without further information and will be edited over time as legacy, or best available data, are updated with authoritative sources. In addition, overlapping designation boundaries are intersected into fee owned lands in the Vector Analysis prioritization process; however, many designation boundaries include private or other inholdings and may result in inflated area calculations by land manager. The PAD-US inventory is now considered functionally complete with the vast majority of land protection types represented in some manner, while work continues to increase update frequency and improve data quality. Estimated completeness of the PAD-US 3.0 inventory is available in Steward Reports at www.protectedlands.net/data-stewards/. Qualitative completeness estimates by federal agency balance acres inventoried and the quality of data/attributes in each inventory, including fee owned parcels, easement interests and major designations. For example, Federal agencies estimate the percent completeness of lands data submitted for PAD-US 3.0 as: NPS (95%), USFS (99%), FWS (89%), BLM (85%), NRCS (85%), and NOAA (95%). The estimated completeness of state aggregations is available from www.protectedlands.net/data-stewards/ (state map). A graphical summary of the "State of PAD-US data" (fee lands only) illustrating spatial data quality and update frequency of the PAD-US, federal, and state agency data is available at: https://communities.geoplatform.gov/ngda-govunits/federal-lands-workgroup/. The USGS continually seeks to improve inventory completeness and spatial data quality in collaboration with agency data-stewards as described in "Completing America's Inventory of Public Parks and Protected Areas: An Action Plan for 2016 - 2020" (2016) available at https://www.usgs.gov/programs/gap-analysis-project/science/pad-us-vision . As a compilation of many data sets, attribute completeness and accuracy may vary. Federal data providers, and most state aggregators, reviewed the translation of their spatial data files into the PAD-US schema and the aggregated database. In addition, the PAD-US team summarized and reviewed the final database and each feature class for overall attribute accuracy and consistency. A formal accuracy assessment of the vertical positional information in the data set is not applicable to the data type.
