Data Quality Information:
Attribute Value Accuracy Information:
Attribute Accuracy Report: Cartographic 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.
Logical Consistency Report: This product is a layered GeoPDF file. GeoPDF is a copyright format with implementation rights held exclusively by TerraGo Technologies. This design is based on use of specific commercial software systems therefore any changes to the software specifications and dependencies will be followed by the USGS and codified in the product standard.
Completeness Report: Each layer of the GeoPDF is extracted from the USGS national geospatial databases. These data are intended to be cartographically complete at a 1:25,000 scale.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: This US Topo map 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. In this product, the projection line, grids, and orthoimage are believed to meet NMAS. Positional accuracy of the other data layers is less controllable because of diversity of data sources, and may not meet NMAS.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report: Vertical accuracy report: US Topo contours are derived from the USGS National Elevation Dataset (NED). Accuracy of the NED is inherited from various sources of digital elevation models used to populate the NED. These data sources vary in vertical accuracy depending on collection method, control accuracy and density, and local terrain relief. The overall absolute vertical accuracy of the NED, as tested against HARN control elevations, is 4.78 meters at 95% confidence level (National Standards for Spatial Data Accuracy). US Topo contours are derived from the NED to generally meet National Map Accuracy Standards (90% of well-defined points in reasonably level terrain test within one-half contour interval of the true ground elevation); however, actual vertical accuracies of individual US Topo quadrangles may not meet that standard. Quadrangles containing collar notes stating contours "May not meet National Map Accuracy Standards" are in areas where the source is known to be questionable for meeting NMAS for the stated contour interval.

Title: Transportation, USFS FSTopo roads
Geospatial Data Presentation Form: Vector digital data
Other Citation Details: The FSTopo database was originally populated with Cartographic Feature File (CFF) data. CFF data were derived from the standard Forest Service Primary Base Series (PBS) or Single Edition Series (SES) map as part of the Forest Service National Geographic Information System Plan. PBS and SES maps were developed from the U.S. Geological Survey 1:24,000-scale, 7.5-minute topographic map series, with enhancements and regular revisions to satisfy Forest Service needs. Except in Alaska, where 1:63,360-scale maps are used, the original USGS 1:24,000-scale source maps were constructed to meet National Map Accuracy Standards, which require that 90 percent of all well-defined features shown on the map are within .02 inches of their true location. CFF data were collected using methods and the best technologies available to ensure that digitized elements were captured within .003 inches of corresponding elements shown on source maps. The USDA Geospatial Service and Technology Center (GSTC) uses the same data collection accuracy standard for additions and revisions to the data. Only maps in USDA Forest Service areas will contain USDA Forest roads.

Title: Transportation, Railroads
Geospatial Data Presentation Form: Vector digital data
Other Citation Details: Railroads are based on unpublished data provided to USGS by the Federal Railroad Administration (FRA). These data were collected by FRA as part of the Automated Track Inspection Program (ATIP). Though not originally intended for mapping purposes, the data are judged by USGS to have high positional accuracy and to be suitable for 1:25,000-scale mapping. The original data were GPS points, which were thinned, filtered, and consolidated by USGS to create the data shown in US Topo. These data are not complete, and the levels of actual completeness within a map cell or for the dataset as a whole are not precisely known. ATIP is an ongoing program, FRA has committed to continue working with USGS, and the data will become more complete with each US Topo production cycle. The USGS has elected to use this mechanism and source of railroad data because no sufficiently current, accurate, and non-proprietary railroad dataset with national coverage can be found. The names of rail lines will be added at some future date. -- For Alaska only, railroad data is provided by the Alaska Railroad Corporation, and may not include other owner's rail features. Unpublished data provided directly to USGS. Current as of 2012. For more information, contact Alaska Railroad Corporation, 327 W.

Title: Hydrography
Geospatial Data Presentation Form: Vector digital data
Other Citation Details: The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. The high-resolution NHD was originally created using 1:24,000-scale data. State and Local Stewards are improving the data by incorporating local updates based on more current and more accurate source data. Water features in the real world are relatively dynamic and the differences at the time of data collection mean that water features may not register exactly to other layers. The hydrographic feature names contained in and displayed by the NHD are extracted and validated from the Geographic Names Information System (GNIS). Spatial objects may be filtered or generalized to achieve a 1:24,000-scale representation. -- For Alaska only, NHD data were originally captured from the 1:63,360 USGS topographic map series. These data are being continually upgraded by the USGS and partner organizations in Alaska. Currency, accuracy, and resolution therefore vary.

Other Citation Details: The Randolph Glacier Inventory (RGI 2.0) is a global inventory of glacier outlines. It is supplemental to the Global Land Ice Measurements from Space initiative (GLIMS). Production of the RGI was motivated by the forthcoming Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). Updates beyond the IPCC 2012 deadlines will take the form of additions to the GLIMS Glacier Database. As resources allow, all these data will be incorporated into the GLIMS Glacier Database. The RGI data are used without alteration by the U.S. Geological Survey for US Topo maps and are not yet integrated with other hydrography features from USGS datasets. Glacier names are from the Geographic Names Information System (GNIS). RGI polygon boundaries are not shown in the US Topo representation.

Title: U.S.-Mexico National Boundary
Other Citation Details: The international boundary between Mexico and the United States, defined as a joint venture between the U.S. Department of Agriculture (USDA) and the Instituto Nacional de Estadística y Geografía of Mexico (INEGI), resulted in an unofficial United States-Mexico boundary dataset that was further enhanced by the U.S. Geological Survey's Border Environmental Health Initiative (BEHI). With the data frame scale set to 1:5,000 in ArcMap, the center of the Rio Grande/Río Bravo was digitized using the NAIP 2004 Imagery. In areas with dense stands of salt cedar (bounding box = UL -104.714 30.038, UR -104.664 30.037, LR -104.666 29.933, LL -104.717 29.934; NAD83), the center of the channel was difficult, and sometimes impossible, to easily determine. To determine the location of the boundary, the GIS analyst compared the location of the line in the INEGI 1:250K Limite feature class with the NAIP 2004 Imagery and adjusted the boundary to the image, thus, the delineation of the international boundary is less certain in these areas. The remaining part of the border was extracted from the INEGI 1:250K Limite feature class and appended to the line feature class created along the Rio Grande/Río Bravo. The U.S. Geological Survey reviewed the original USDA data against 2007 NAIP imagery and further edited 9 line segments in the Rio Grande areas to conform to National Map Accuracy Standards.

Title: USFWS Simplified Wildlife Refuge Boundary
Geospatial Data Presentation Form: Vector digital data
Other Citation Details: This data set depicts simplified boundaries of lands administered by the U.S. Fish and Wildlife Service including National Wildlife Refuges, National Fish Hatcheries, FWS administrative sites, and other conservation areas. The Alaska National Wildlife Refuge Boundaries data set depicts the legislative boundary of the 16 National Wildlife Refuges in Alaska at a source scale of 1:63,360. The dataset was created by the U.S. Fish and Wildlife Service, Region 7, Division of Realty and Natural Resources. The USGS substituted the Alaska National Wildlife Refuge boundaries for the USFWS Simplified Wildlife Refuge Boundaries in Alaska for cartographic purposes. The USFWS Simplified Wildlife Refuge Boundaries are simplified from the U.S. Fish and Wildlife Service Real Estate Interest data layer containing polygons representing tracts of land (parcels) in which the Service has a property or management interest. These interests include full land ownership, secondary interests in property primarily managed and reported by other federal agencies, leased property, property managed by agreement with other parties, and, within National Wildlife Refuges, property governed by conservation easements. A conservation easement is a permanent, legally enforceable land preservation agreement between a landowner and a government agency that restricts real estate, commercial and industrial development of the land, which remains private property. Inholdings of private property within Refuge areas not covered by conservation easements are excluded from these boundaries. The Hawaiian Islands National Wildlife Refuge and Waterfowl production area easements acquired through the small wetlands program have been omitted. Interior boundaries between parcels were dissolved to produce a single set of simplified external boundaries for each feature. These are resource grade mapping representations of the U.S. Fish and Wildlife Service boundaries. For legal descriptions of the land represented here contact the USFWS Realty Office. This map layer was compiled by the U.S. Fish and Wildlife Service. The Alaska National Wildlife Refuges dataset was derived from the following digital sources and legal documents: 1) Federal Register, Vol. 48, No. 38 Thursday, February 24, 1983 Notices Pages 7890-8029. 2) USGS 1:250,000 scale Alaska Boundary Series maps entitled: Alaska National Interest Lands Conservation Act December 2, 1980 P.L. 96-487 3) Various legal documents such as survey plats, legal metes and bounds descriptions, Deeds, and Titles. 4) USGS 1:63,360 scale revised hydrography Digital Line Graphs depicting ground conditions from 1955 to 1986. Although these Fish and Wildlife boundaries represent lands administered by the U.S. Fish and Wildlife Service, not all areas are open to the public. Some fragile habitats need to be protected from human traffic, some management areas are closed, and the terms of some conservation easements preclude public access. The public is urged to contact specific Refuges or other conservation areas before visiting. -- For Alaska only, the FWS Boundaries are from the dataset "Alaska National Wildlife Refuge Boundaries" available at https://alaska.fws.gov/nwr/realty/data.htm

Other Citation Details: General: The Bureau of Land Management is the authoritative source for PLSS information. However, the management of these data is not completely uniform throughout the country; some variations in sources and characteristics are documented in the following sections. Although this metadata record is included with all maps, PLSS is currently shown on US Topo maps in only a few states. PLSS will be added to US Topo maps in more states in the coming years. -- For Alaska, PLSS data for US Topo in Alaska consist of protracted (computed, not surveyed) data only. Section boundaries were generated from geodetic latitude and longitude coordinate pairs as recorded on BLM's official protraction diagrams of the state of Alaska. The SDMS_PROD protraction tables were modified to include pro_pt83, section83, and township83. The latitude and longitude values in the pro_pt83 table were transformed from geographic NAD27 coordinates to geographic NAD83 coordinates using NADCON for Alaska. The Informix Section83 table is a spatially-enabled table that contains all of the protraction information for each of the 655,483 sections. Section shapes are stored as NAD83 geographic multipolygons. Each section was individually constructed from NAD83 geographic pro_pt (Protracted Point) table and is fully densified by including all township/section offset corners from adjacent ownship/sections.

Title: Hypsography - Alaska
Geospatial Data Presentation Form: Vector digital data
Other Citation Details: The intended viewing scale for US Topo contours is approximately 1:24,000. US Topo contours are generated from the 1/3 arc-second layer of the National Elevation Dataset (NED). This NED layer is created using data from a variety of sources including stereoscopically-compiled contours from legacy USGS topographic maps, high-resolution stereo-compilation of mass-points and breaklines, and airborne lidar and ifsar (Alaska only) topographic measurement technologies. These sources yield varying ranges of vertical accuracy, although the USGS is continually improving the NED accuracy with ifsar and lidar derived elevations. Most US Topo contours in Alaska are derived from ifsar source which is collected to meet NMAS for only contour intervals of 20 feet or greater; however, 10 foot contour intervals are displayed on approximately 40% of Alaska quadrangles in order to provide some reasonable level of terrain detail. Alaska 10-foot interval quadrangles from ifsar contain a statement that they may not meet NMAS for that contour interval. Quadrangles containing collar notes stating contours "May not meet National Map Accuracy Standards" are in areas where the source is known to be questionable for meeting NMAS for the stated contour interval. For more specific information on NED source data and accuracy visit ned.usgs.gov. US Topo contour generation process: A low-pass filter is applied to the NED 1/3 arc-second data layer to smooth contours primarily in areas of lidar source. Except in areas of lidar source, the NED elevation surface is further modified to conform to flow lines and water bodies from the National Hydrography Dataset (NHD) in order to improve spatial agreement between the hypsography and updated hydrographic features. The contour lines are then interpolated from the raster grid and output in the UTM projection. There is no guarantee or warranty concerning the accuracy of the data. Users should be aware that temporal changes may have occurred since these data were collected and that some parts of these data may no longer represent actual surface conditions. Hydro-feature alignment and generalization also alter the spatial characteristics of the contours. Users should not rely on US Topo contours for high-accuracy applications, but instead, should obtain data of suitable resolution and accuracy from the NED or other sources. -- For Alaska only, the original source of most elevation data for Alaska is IfSAR data collected through the Alaska Statewide Digital Mapping Initiative (SDMI). These data are further processed by USGS and stored in the National Elevation Dataset (NED). See https://www.alaskamapped.org/sdmi/ for more information about the SDMI program and data.

Title: Land Cover - Woodland
Geospatial Data Presentation Form: Vector digital data
Other Citation Details: The Woodland Tint is a derivative land cover product created using four national map layers: one raster layer, National Land Cover Database (NLCD) 2001 (Land Cover); and three vector layers (National Hydrography Dataset, Transportation Roads, and Transportation Airports). The process begins with combining three NLCD 2001 Land Cover V1 Classes (41 Deciduous Forest, 42 Evergreen Forest, and 43 Mixed Forest). The resulting raster data was resampled to 5 meter pixels, converted to woodland vector polygons, and smoothed via the Paek Algorithm. The woodland polygons are masked with buffered Transportation and Hydrography (NHD Areas excluding Inundation Areas and NHD Waterbodies excluding Swamp/Marsh). The resulting polygons are checked for scale appropriate size (minimum size of one acre), and the small woodland polygons as well as small clearings within the woodland polygons are deleted.

Title: Shaded Relief
Geospatial Data Presentation Form: raster digital data
Other Citation Details: The Shaded relief is a derivative elevation product created from the National Elevation Dataset (NED) 1/3 arc second. First there are five separate shaded relief datasets created from the original data. Each shaded relief has different azimuths and altitude values as follows: 00 450, 1350 600, 2700 450, 3150 450, 450 450. These five datasets are then combined into one feature class using map algebra to compute the raster layers using the following equation shadedrelief1 + shadedrelief2 + shadedrelief3 + (shadedrelief4 x 2) + shaded relief5 \ 6. This equation gives double importance to the 3150 azimuth and 450 elevation.
