US Topo maps have a credit legend in the lower left-hand corner of the map collar. This includes a short summary of data sources and data currency.
More detailed source information is in an XML metadata file attached to each GeoPDF file. This file contains series-level, quad-level, and layer-level metadata, but US Topo does not preserve or track feature-level metadata. Open the GeoPDF map file in Acrobat Reader and click on the paperclip icon to access the metadata file (a US Topo Map Symbols file is also attached).
Two metadata XML documents—one for the map and one for the orthoimage—are included with GeoTIFF files downloaded from TopoView.

How do I find, download, or order topographic maps?
The U.S. Geological Survey (USGS) has been the primary civilian mapping agency of the United States since 1879. USGS topographic maps have been published at many scales, but 1:24,000 (also referred to as a 7.5-minute quadrangle) has been the standard topographic map scale since 1947. For Alaska the standard scale is 1:25,000. All dates and all scales of our topographic maps can be freely...
Will US Topo maps become part of the Historical Topographic Map Collection when a newer version is published?
Superseded US Topo maps will remain available for download, but will not become part of the Historical Topographic Map Collection, which is scans of USGS topographic quadrangles originally published as paper documents between 1884-2006. The first US Topo maps were published in 2009. They are updated and superseded every 3 years (maps for one third of the country are produced every year). This does...
How current are US Topo maps?
US Topo maps are updated on a three-year production cycle (maps covering one third of the country are updated each year). The US Topo production schedule follows the U.S. Department of Agriculture's National Agricultural Imagery Program (NAIP) collection schedule. This does not include US Topos for Alaska, which are on a different schedule. The linework features shown on the maps are generated...
Can I import a US Topo map into my Geographic Information System (GIS)?
Most Geographic Information System (GIS) vendors do not yet provide geospatial PDF import capabilities. US Topo maps are derived from GIS data sets and are formatted as PDF for the benefit of non-specialist users. We consider the product to be primarily an output of—rather than an input to—GIS. However, we recognize the demand for symbolized maps in GIS, and we are working on a companion product...
How accurate are US Topo maps, and why don't they have an accuracy statement?
US Topo maps are as accurate as the data sources used to make them, but because these sources are many and varied, it is not possible to make a single simple statement that the map as a whole meets a particular level of accuracy. US Topo maps, therefore, do not have a traditional accuracy statement in the map collar. Accuracy information for individual data sources is included in the metadata file...
How do US Topo maps differ from historical USGS topographic maps?
Historically, USGS topographic maps were made using data from primary sources including direct field observations. Those maps were compiled, drawn, and edited by hand. By today's standards, those traditional methods are very expensive and time-consuming, and the USGS no longer has funding to make maps that way. A new USGS topographic map series was launched in 2009 and branded "US Topo." Though...

US Topo Product Standard
This document defines a U.S. Geological Survey (USGS) digital topographic map. This map product series, named “US Topo,” is modeled on the now historical USGS 7.5-minute (1:24,000 scale) topographic map series produced and printed by the USGS from 1947 to 2006. US Topo maps have the same extent, scale, and general layout as the historical topographic maps. US Topo maps incorporate an orthorectifieAuthorsLarry R. Davis, Kristin A. Fishburn, Helmut Lestinsky, Laurence R. Moore, Jennifer L. WalterUS Topo—Topographic maps for the Nation
Building on the success of 125 years of mapping, the U.S. Geological Survey created US Topo, a georeferenced digital map produced from The National Map data. US Topo maps are designed to be used like the traditional 7.5-minute quadrangle paper topographic maps for which the U.S. Geological Survey is so well known. However, in contrast to paper-based maps, US Topo maps provide modern technologicalAuthorsKristin A. Fishburn, William J. CarswellTopographic map symbols
Interpreting the colored lines, areas, and other symbols is the first step in using topographic maps. Features are shown as points, lines, or areas, depending on their size and extent. For example, individual houses may be shown as small black squares. For larger buildings, the actual shapes are mapped. In densely built-up areas, most individual buildings are omitted and an area tint is shown. OnAuthors - News
