Description:
- Abstract: Layered geospatial PDF 7.5 Minute Quadrangle Map. Layers of geospatial data include orthoimagery, roads, grids, geographic names,
elevation contours, hydrography, and other selected map features. This map is derived from GIS (geospatial information system) data. It
represents a repackaging of GIS data in traditional map form, not creation of new information. The geospatial data in this map are from
selected National Map data holdings and other government sources.
- 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.

Data Quality Information:
-
Attribute Value Accuracy Information:
- Attribute Accuracy Report: 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.
- Logical Consistency Report: This product is a layered geospatial PDF file.
- Completeness Report: 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.
-
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. However, other vector layers do generally register well with the orthoimage, which is evidence that the
overall accuracy is close to meeting NMAS.
-
Vertical Positional Accuracy:
- Vertical Positional Accuracy Report: 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.

- Publication Date: 20020401
- Title: Hypsography
- Geospatial Data Presentation Form: Vector digital data
- Other Citation Details: 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.

- 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.

- 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.

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

- Geospatial Data Presentation Form: vector digital data
- Other Citation Details: 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. 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.

- Geospatial Data Presentation Form: raster digital data
- Other Citation Details: 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.
