U.S. Geological Survey, National Geospatial Technical Operations Center 20190626 USGS National Transportation Dataset in FileGDB 10.1 format (published 20190626) vector digital data Reston, VA U.S. Geological Survey Layers of geospatial data include roads, airports, trails, and railroads. The geospatial data are from selected National Map data holdings and other government sources. This dataset contains transportation layers. 2008 2012 publication date Complete Irregular -176.958909000348 179.452979999554 71.3489679996688 -14.3665539995753 ISO 19115 Topic Category transportation None Roads Airports Airstrips Railways Airport Complex Airport Point Airport Runway Geographic names Trail Transportation Waterway Trails National Transportation Dataset (NTD) National FileGDB 10.1 Geographic Names Information System US United States None None. However, users should be aware that temporal changes may have occurred since this data set was collected and that some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Acknowledgment of the U.S. Geological Survey would be appreciated for products derived from these data. withheld Thumbnail JPG image JPEG Content is derived from USGS national geospatial databases. The data is owned and hosted by the USGS, but does not preclude using data sources owned and hosted by other organizations, provided that these sources have been approved by the USGS data program. The data was extracted and updated according to standards set by the USGS. Each layer is extracted from the USGS national geospatial databases. This product is compiled to meet National Map Accuracy Standards (NMAS). NMAS horizontal accuracy requires that at least 90 percent of well-defined points tested are within 0.02 inch of the true position. Vertical accuracy is not applicable to this dataset. Federal Railroads Administration 20190626 Transportation, Railroads Vector digital data Railroad are acquired annually from the FRA. Rail lines and sidings are converted into the National Transportation Dataset. The rail lines layer represents the freight lines of the nation's railroad system. The data set covers all 50 states and the District of Columbia, as well as territories and possessions of the United States. No rail lines exist in American Samoa, Guam, Northern Mariana Islands, and the Virgin Islands of the US. 24000 digital data 2016 2016 publication date Federal Railroads Administration Main track centerlines Federal Aviation Administration 20190626 Airports Vector digital data Airport points and runway polygons are for Federal Aviation Administration (FAA)-recognized public and private airports in the United States. FAA airports and runway shapefiles are used to the update the existing airports and runways in the National Transportation Dataset. Digital data were inspected for attribute accuracy, spatial accuracy, and completeness. withheld 24000 digital data 2011 2012 publication date Transportation - Airports runways Various government agencies and volunteer organizations 20190626 Recreational Trails Vector digital data The first recreational trails were added to US Topo maps in 2013. The data for trails come from a variety of sources. Accuracy and currency is the responsibility of the data owner; USGS evaluates the authoritativeness of the source but does not independently verify data accuracy. Trails are not complete, and will not be complete for the foreseeable future. Trails will be added as data become available from land management agencies and other authoritative sources. All recreational trails information presented on US Topo maps is public domain, though the original source data is not necessarily public domain. This metadata section documents all data sources for all maps, not this specific map. Trails listed here are not guaranteed to be present on all relevant maps, due to schedule differences between data delivery and US Topo production schedules. Feature-level metadata is not provided in the US Topo product; there is no link between a line on the map and the source of that specific trail. Notes on data sources follow --------- For the 11 National Scenic Trails (NST): Ice Age National Scenic Trail: data provided by the volunteer organization Ice Age Trail Alliance, http://www.iceagetrail.org, in cooperation with National Park Service and Wisconsin Department of Natural Resources. - Pacific Crest National Scenic Trail: unpublished data provided by US Forest Service - Appalachian National Scenic Trail: data published by the Appalachian Trial Conservancy, http://appalachiantrail.org/about-the-trail/mapping-gis-data, in cooperation with National Park Service - North Country National Scenic Trail: unpublished dataset provided by National Park Service - Arizona National Scenic Trail: data from AZGEO Clearinghouse, https://azgeo.az.gov/azgeo/, in cooperation with U.S. Forest Service - Pacific Northwest National Scenic Trail: unpublished data provided by US Forest Service - Natchez Trace National Scenic Trail: unpublished dataset provided by National Park Service --------- For other trail types and sources: US Fish and Wildlife Service lands: the USFWS Hiking Trails Inventory is administered by the US Department of Transportation Federal Highway Administration, and Pacific Western Technologies, LTD. The purpose of the dataset is to create a baseline inventory of all non-motorized trails on US Fish and Wildlife Service Stations. - US Forest Service lands: trails within National Forests are from unpublished data provided by USFS. These data are developed from sources of differing accuracy. US Topo does not portray access and travel management information indicating which trails are managed for or open to specific modes of travel (motorized/non-motorized) or associated seasons of use. USFS trails (other than selected NSTs described above) are currently shown on US Topo only in Colorado. - The International Mountain Bicycling Association, IMBA, shares their bicycle trails data with USGS as part of an ongoing partnership. IMBA-collected trails are generally not shown inside delineated Federal lands (e.g., National Forests) on US Topo maps. https://www.nps.gov/subjects/nationaltrailssystem/index.htm http://www.pnts.org http://www.fws.gov/gis/data/national/ https://www.imba.com/ 24000 digital data 2006 2018 publication date Recreational Trails Trail centerline U.S. Census Bureau, Geography Division 20190626 Transportation, Census Roads vector digital data Dataset source is Census Bureau MAF/TIGER database extracts in the form of TIGER/Line Shapefiles. The TIGER/Line shapefiles and related database files are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent dataset, or they can be combined to cover the entire nation. The U.S. Geological Survey filters Census roads to remove short road segments which are less than 500 feet in length, are not named and are classified as local roads. The USGS National Transportation Dataset functional road classification system is applied to the Census datasets. The original TIGER/Line Shapefile products are not copyrighted however TIGER/Line and Census TIGER are registered trademarks of the U.S. Census Bureau. The horizontal spatial accuracy information present in the TIGER/Line shapefiles is provided for the purposes of statistical analysis and census operations only and the data may not be suitable for high-precision measurement applications. Full metadata for TIGER/Line shapefiles is available from U.S. Census Bureau http://www.census.gov/geo/maps-data/data/tiger.html 24000 digital data 2013 2018 publication date Roads - Census Road centerlines, route numbers, road classification, street names Alaska Railroad Corporation 20190626 Transportation, Railroads Vector digital data This record applies to Alaska data only.
