      <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>

      <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>

      <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>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>

            <title>FWS Interest Simplified Boundaries</title>
            <geoform>vector digital data</geoform>
            <othercit>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.</othercit>

            <othercit>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 http://www.geocommunicator.gov/GeoComm/metadata/index.htm#PLSS, 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.</othercit>

            <geoform>Vector digital data</geoform>
            <othercit>This contour featureclass was generated from the 1/3 arc-second version of the 3D Elevation Program. The intended
              viewing scale for these features is 1:24,000. The contours are derived from a filtered elevation raster to achieve
              smoother arcs. In some areas, the 3DEP data may be modified by the National Hydrography Dataset (NHD) flow lines and water
              bodies to facilitate improved integration between the hypsography and hydrography on USGS map products. These contours
              were generated primarily for use as a layer in GeoPDFs created in the digital mapping program. The raster data source of
              contours 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 the
              DEM prior to contour generation. The goals of the hydro-enforcement are to prevent contour lines from extending over the
              surface of water bodies and to align the contour reentrants with the NHD single- line streams. The 3DEP raster cells are
              converted to points. Those points, along with the NHD flow lines are input into an interpolation tool to create a new
              surface. The NHD water bodies and areas are preprocessed to attach the minimum and maximum elevation to each polygon. From
              these precalculated values, an appropriate value is calculated by which to raise the elevation cells under the NHD
              polygons. The NHD polygons are then converted into rasters, which in turn will be used to generate a mosaic that includes
              the new raster surface. The mosaic is filtered to provide smoother contour lines. Contours are generated and depression
              and index contours are identified. 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>

            <title>Shaded Relief</title>
            <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>

        <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.
