Cartographic content is derived from USGS national geospatial databases. Most the data are owned and hosted by the USGS, but this does not preclude using data sources owned or hosted by other organizations, provided that these sources have been approved by the USGS data program.
This product is a layered geospatial PDF file.
Each PDF layer is derived from data extracted from USGS national geospatial databases. These data are intended to be cartographically complete at 1:24,000 scale.
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. However, other vector layers do generally register well with the orthoimage, which is evidence that the overall accuracy is close to meeting NMAS.
Vertical accuracy report: US Topo contours are derived from the USGS 3D Elevation Program (3DEP) 1/3 arc-second DEM data. Accuracy of 3DEP is inherited from various sources. These data sources vary in vertical accuracy depending on time of collection, collection method, control accuracy and density, and local terrain relief. The overall absolute vertical accuracy of the 1/3 arcsecond DEM data, as tested against GPS control, is about 3 meters at 95% confidence level (National Standards for Spatial Data Accuracy). US Topo contours are derived from the DEMs 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.

Hypsography
Vector digital data
This contour featureclass was generated from the 1/3 arc-second version of the 3D Elevation Program. The intendedviewing scale for these features is 1:24,000. The contours are derived from a filtered elevation raster to achievesmoother arcs. In some areas, the 3DEP data may be modified by the National Hydrography Dataset (NHD) flow lines and waterbodies to facilitate improved integration between the hypsography and hydrography on USGS map products. These contourswere generated primarily for use as a layer in GeoPDFs created in the digital mapping program. The raster data source ofcontours is the 3D Elevation Program 1/3 arc-second layer. Secondary datasets include the high resolution flow lines,water bodies, and areas from the National Hydrography Dataset (NHD). The NHD layers are used in hydro-enforcement of theDEM prior to contour generation. The goals of the hydro-enforcement are to prevent contour lines from extending over thesurface of water bodies and to align the contour reentrants with the NHD single- line streams. The 3DEP raster cells areconverted to points. Those points, along with the NHD flow lines are input into an interpolation tool to create a newsurface. The NHD water bodies and areas are preprocessed to attach the minimum and maximum elevation to each polygon. Fromthese precalculated values, an appropriate value is calculated by which to raise the elevation cells under the NHDpolygons. The NHD polygons are then converted into rasters, which in turn will be used to generate a mosaic that includesthe new raster surface. The mosaic is filtered to provide smoother contour lines. Contours are generated and depressionand index contours are identified. There is no guarantee or warranty concerning the accuracy of the data. Users should beaware that temporal changes may have occurred since these data were collected and generated and that some parts of thesedata may no longer represent actual surface conditions. Hydro-enforcement and generalization can also significantly alterthe spatial characteristics of the contours. Users should not use these data for critical applications without a fullawareness of its limitations.

Land Cover - Woodland
Vector digital data
The Woodland Tint is a derivative land cover product created using the most recent National Land Cover Database (NLCD) raster data, as well as vector data from the National Hydrography Dataset and National Transportation Dataset. For CONUS, Hawaii, and Puerto Rico/U.S. Virgin Islands, NLCD Tree Canopy Cover is masked with NLCD Percent Developed Imperviousness (values from 1-100). The resulting dataset with Tree Canopy Cover of 20-100% is used as the input raster to generate woodland polygons. For Alaska, 3 values (41 -Deciduous Forest, 42 - Evergreen Forest, and 43 - Mixed Forest) are extracted from NLCD Land Cover to create the input raster used to generate woodland polygons. The woodland polygons are masked with buffered Transportation (Roads, Airport Runways, and Railroads) and Hydrography (NHD Areas excluding Inundation Area 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. Resulting woodland vector polygons are smoothed via the PAEK Algorithm.

Hydrography
vector digital data
The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies thestream segments or reaches that make up the nation's surface water drainage system. The high-resolution NHD was originallycreated using 1:24,000-scale data. State and Local Stewards are improving the data by incorporating local updates based onmore current and more accurate source data. Water features in the real world are relatively dynamic and the differences atthe time of data collection mean that water features may not register exactly to other layers. The hydrographic featurenames 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.

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 driveways and short local unnamed road segments which are less than 500 feet in length. The USGS National Transportation Dataset functional road classification system is applied to the Census datasets. The functional road class includes, limited access highway, secondary highway, local connector, local road 4wd, tunnel, ferry route, and closed. Closed roads were approved in 2020 to align with USFS schema and will be incorporated into the NTD in 2021. 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.

FWS Interest Simplified Boundaries
vector digital data
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.

vector digital data
The PLSS information is for general reference purposes only, and should not be used to determine legal boundaries or land ownership. The Bureau of Land Management (BLM) is the authoritative source for PLSS information at the federal level, and the US Topo representation is derived from BLM GIS data files called Cadastral National Spatial Data Infrastructure or CadNSDI. The management of these data is not completely uniform throughout the country. Although this metadata record is included with all maps, PLSS is currently shown on US Topo Maps for only a few states. PLSS will be added to US Topo maps in more states in coming years as BLM authorized CadNSDI format is made available. The three layers USGS stores from PLSS are the Township, First Division and Special Surveys. Metadata for BLM PLSS data is at https://navigator.blm.gov/home, though this URL may change in the near future. Alternate sources of PLSS data will continued to be served mainly in western states where BLM is the data steward or the data is from a trusted source. Notes on individual states follow,----Alaska PLSS consists of protracted (computed, not surveyed) data only. For more information see http://sdms.ak.blm.gov/sdms/data_protracted_grid_gis.html ----Ohio was the original PLSS state in the early 1800s, and the land network there is unusually complex. The source data include four first-division parcel types. These are all shown on US Topo maps, and are labeled according to BLM's attribution, with a leading letter followed by either a number or more letters. The meanings of the leading letters are S=Section, F=Fractional Section, L=Lot, Q=Quarter Township.

Wetlands - Emergent and Forest/Shrub
vector digital data
This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. While the Fish and Wildlife Service produces a variety of wetland categories, only two (Emergent and Forest/Shrub wetlands as defined by Cowardin et al. (1979)) are included on US Topo Maps.The emergent wetlands depicted do not include lakes, rivers, open water ponds, deepwater marine and estuarine features or non-vegetated, farmed, intermittent and temporarily flooded wetlands. The goal is to provide a visual depiction of the approximate location and extent of Emergent and Forest/Shrub wetlands. Digital wetlands data are intended for use with base maps and digital aerial photography at a scale of 1:12,000 or smaller. Due to the scale, the primary intended use is for data display on the US Topo Maps. This data display is not intended for analysis. The map products were neither designed or intended to represent legal or regulatory products. Questions or comments regarding the interpretation or classification of wetlands can be addressed by visiting https://www.fws.gov/wetlands/FAQs.html These data were developed in conjunction with the publication Cowardin, L.M., V. Carter, F.C. Golet, and E.T. LaRoe. 1979. Classification of Wetlands and Deepwater Habitats of the United States. U.S. Department of the Interior, Fish and Wildlife Service, Washington, DC. FWS/OBS-79/31. For more information on the wetland classification codes visit https://www.fws.gov/wetlands/Data/Wetland-Codes.html.

Shaded Relief
raster digital data
The Shaded relief is a derivative elevation product created from the USGS 3D Elevation Program (3DEP) 1/3 arc-second DEM data. 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.
