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.

The first recreational trails were added to US Topo maps in 2013. The data for these features come from a variety of sources.
Trails are not complete, and will not be complete for the foreseeable future; the near-term objectives of the US Topo program
are to show recreational trails on federal lands and those that are part of the National Trails System. Trails will be added
as data become available from land management agencies and other authoritative sources. At this time all recreational trails
data used for US Topo are public domain. General information about the National Trails System and its components can be found
at http://www.nps.gov/ncrc/programs/nts/nts_trails.html and http://www.pnts.org and http://www.fws.gov/gis/data/national/index.html#NWRS
This metadata section documents all data sources used for any map; the features and data described here are not necessarily
present on this specific map. Notes on individual data sources follow -- Ice Age National Scenic Trail: one of 11 National
Scenic Trails (NST). The Ice Age NST is in Wisconsin. The data used on US Topo were provided by the volunteer organization
Ice Age Trail Alliance, http://www.iceagetrail.org, in cooperation with National Park Service and Wisconsin Department of
Natural Resources. -- Pacific Crest National Scenic Trail: Data used on US Topo provided by US Forest Service, and published
at http://www.fs.usda.gov/detail/pct/home/ -- Pacific Northwest National Scenic Trail: data used on US Topo is an unpublished
dataset provided by US Forest Service -- US Fish and Wildlife Service lands: the USFWS Hiking Trails Inventory is administered
by the US Department of Transportation Federal Highway Administration, and Pacific Western Technologies, LTD. The purpose
of the dataset is to create a baseline inventory of all non-motorized trails on US Fish and Wildlife Service Stations. - US
Forest Service lands: trails within national forests are from unpublished data provided by USFS. These data are developed
from sources of differing accuracy. US Topo does not portray access and travel management information indicating which trails
are managed for or open to specific modes of travel (motorized/non-motorized) or associated seasons of use. USFS trails (other
than selected NSTs described above) are currently shown on US Topo only in Colorado.

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.

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.

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 Estad stica y Geograf a 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/R o 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/R o 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.

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.

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. 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.
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. 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.

viewing scale for these features is 1:24,000. The contours are derived from a filtered elevation raster to achieve smoother
arcs. The NED data were 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 US Topo digital mapping program. The raster data source of contours is the National Elevation
Dataset (NED) 1/3 arc-second layer. The 1/3 arc-second NED contains resampled data from the 1/9 arc-second layer of NED. 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 NED 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.

The Woodland Tint is a derivative land cover product created using several national map layers: three National Land Cover
Database (NLCD) 2001 raster layers (Tree Canopy, Imperviousness, and Land Cover); and two vector layers (National Hydrography
Dataset and Transportation). The process begins with masking the NLCD 2001 Canopy Data with NLCD 2001 Imperviousness V1 (values
from 1-100), and Land Cover V1 (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 four vector layers (National Hydrography Dataset, Transportation Roads, Transportation Airports
and Transportation Railroads). 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.

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.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
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.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description
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.
