      <abstract>US Topo map converted from GeoPDF/Geospatial PDF to GeoTIFF. Geospatial data included in each map varies, but may include orthoimagery, roads, grids, geographic names, elevation contours, hydrography, and other selected map features. US Topo GeoPDF maps were designed specifically for the capability to turn individual layers on and off. GeoTIFFs do not provide for that capability and thus, certain layers will not be available on the GeoTIFFs that are available in the PDFs. The selection of layers to show on the GeoTIFFs was based solely on cartographic design, and so it is recommended that the PDF be downloaded if there is interest in the full set of layers. For each PDF published since October 2013, two GeoTIFFs are available. PDF maps published prior to that date are not available in GeoTIFF. Both GeoTIFFs exclude shaded relief, woodland, and several Federal Administrative Land boundary layers (National Cemetery, Department of Defense, Bureau of Land Management, Fish and Wildlife and Native Lands) specifically for reasons of clarity based upon the cartographic design. One of the GeoTIFFs has the orthoimage layer turned off, and the other has the orthoimage turned on. In the latter case, contours and wetlands layers also are turned off, again for cartographic clarity. Data layers not included in the GeoTIFFs can be added to the map depiction in a GIS by downloading the associated file from The National Map (TNM), or by linking to a map service. For example, the woodland polygon data layer is available for download. This data was derived and generalized from the National Land Cover Dataset (NLCD) which is also available as a map service from TNM provide a woodland representation.</abstract>
      <purpose>This map depicts geographic features on the surface of the earth. It is a general purpose map for users who are not GIS experts. One
        intended purpose is to support emergency response at all levels of government.</purpose>

    <complete>Feature content is extracted from the USGS national geospatial databases. These data are intended to be cartographically complete at the scales that the map is produced, 1:24,000 scale in the conterminous 48 states and Hawaii, 1:25,000 scale in Alaska, and 1:20,000 scale in Puerto Rico and the Virgin Islands.</complete>
    <posacc>
      <horizpa>
        <horizpar>US Topo map products in GeoPDF are 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. The digital GeoTIFF version of the map was created with a methodology that preserves, but does not exceed, the accuracy of the original GeoPDF/Geospatial PDF map.</horizpar>
      </horizpa>
      <vertacc>
        <vertaccr>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.</vertaccr>

            <othercit>US Census Bureau's MAF/TIGER dataset is the primary source of roads in the USGS National Transportation Dataset (NTD). USGS
              converts TIGER roads to USGS NTD schema, performs minimal QC/edit, and loads the data into the NTD for use in The National Map viewer
              and US Topo maps. USFS roads replace TIGER roads on US Topo maps over US Forest Service National Forests and National Grasslands. Due to
              different vintages of the data and different road requirements of the agencies, misjoins along USFS boundaries are possible. In 2016,
              USGS started integrating National Parks Service into the NTD. As other federal agencies road data becomes available, their data may be
              incorporated into US Topo maps as well. US Topo maps created in the period of 2010-2015 contain commercially licensed road data with
              copyright restrictions; see individual product credit notes and metadata files for information.</othercit>

            <othercit>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.</othercit>

            <geoform>vector digital data</geoform>
            <othercit>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 http://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 http://www.fws.gov/wetlands/Data/Wetland-Codes.html. Note that coastline delineations were drawn to follow
              the extent of wetland features as described by this project and may not match the coastline shown in other base maps.</othercit>

            <othercit>General: US Topo maps are not legal documents. The PLSS information shown on these maps 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. The management of these
              data is not completely uniform throughout the country. Notes for selected 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.--- Surveys in some western states are too complex to depict completely on a general-purpose topographic map. Issues include
              separate and overlapping surveys, and land grants that pre-date the PLSS system. Old land grants are generally not shown on US Topo
              (though there are some exceptions), and in areas of overlapping surveys only one is shown. </othercit>

            <othercit>Contours are generated from the USGS 3D Elevation Program (3DEP) 1/3 arc-second DEM data. The intended viewing scale for these
              features is 1:24,000. The contours generated from the 1/3 arc-second DEM data are, in some cases, modified by hydro-enforcement with the
              National Hydrography Dataset (NHD) flow lines and water bodies to improve hydro-contour integraion. Contours in areas where the 1/3
              arc-second DEMs were generated for new high resolution lidar may not be hydro-enforced in this way, with the result that hydro features
              and contours may not visually align. Contours are generated primarily for use as a layer in GeoPDFs created in the US Topo digital
              mapping program, and for corresponding vector products. The 1/3 arc-second product is derived from a wide variety of sources, with
              varying accuracies. As of 2017, only about 30% of the country has been covered with lidar elevation data. 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 generated and that some parts of these data may no longer represent actual surface conditions. Hydro-enforcement and
              generalization can also significantly alter the spatial characteristics of the contours. Users should not use these data for critical
              applications without a full awareness of its limitations.</othercit>

            <geoform>Vector digital data</geoform>
            <othercit>The Woodland Tint is a derivative land cover product created using several national map layers: three National Land Cover
              Database (NLCD) 2011 raster layers (Tree Canopy, Imperviousness, and Land Cover); and two vector layers (National Hydrography Dataset
              and Transportation). The process begins with masking the NLCD 2011 USFS Tree Canopy cartographic product with NLCD 2011 Percent
              Developed Imperviousness (values from 1-100), and NLCD 2011 Land Cover (value 11 = Open Water). The resulting raster data with canopy
              values of 20 and greater are converted to woodland vector polygons and smoothed via the Paek Algorithm. 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. For Alaska, the Woodland Tint is a
              derivative land cover product created using five national map layers: one raster layer, National Land Cover Database (NLCD) 2001 (Land
              Cover); and two vector layers (National Hydrography Dataset and Transportation). 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 converted to
              woodland vector polygons, and smoothed via the Paek Algorithm. The woodland polygons are masked with buffered Transportation (Roads,
              Airport Runways, and Railroads) 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.</othercit>

            <geoform>raster digital data</geoform>
            <othercit>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.</othercit>

      <procstep>
        <procdesc>All geospatial content is taken from national geospatial databases under the stewardship of USGS data programs. The NAIP and SPOT imagery is provided by a seamless tile service that delivers image data at a predetermined resolution and quality. The raster and vector data, including grids and collar information, are processed using ESRI ArcGIS software and exported as a geospatial PDF using ESRI ArcGIS software. Map formatting is performed using a custom application, which includes post-processing to embed the metadata XML document and legend. The final GeoTIFF produced from the PDF is downsampled to 300 PPI, compressed, and zipped with an external metadata file. In addition, the projection of the GeoTIFFs are modified to accommodate a rotation of the maps so that the data frame is square to the page(the central meridian is shifted, modifying the projection from Universal Transverse Mercator to Transverse Mercator). All properties of the original PDF projection are retained.
