Hi folks,
The U.S. Geological Survey is pleased to introduce the new US Topo, a
digital 1:24,000-scale topographic map series for 2010. US Topo is a
major new step in regenerating, improving, and updating the familiar USGS
topographic maps. The new maps are built from the digital layers of The
National Map, which is a synthesis of information from local, state, and
federal partners. The US Topo maps combine the familiar data layers seen
in the original map - contours, hydrography, transportation, geographic
names, and more - over an image background. The map?s collar and frame
have the same look and feel as the legacy USGS topographic map. While the
maps are built from digital components, users can print the maps showing
different layers and at different scales.
US Topo builds on the earlier introduction of the "Digital Map - Beta."
More than 14,100 "Digital Map - Beta" quadrangle maps have been produced
since June of 2009, with coverage in 18 states including Maine. These
maps were a developmental precursor to the US Topo and, while similar in
appearance to USGS topographic maps, did not include the hydrography and
contour lines. US Topo adds these layers and other improvements and will
now be the foundation upon which future enhancements and additional data
are added. US Topo maps will be produced in 2010 and 2011 to complete
coverage of the continental United States. For 2010, US Topo production
begins in Kansas and progresses to New York, Oklahoma, Kentucky, and Texas
toward a total of 16 states. In 2012, the existing "Digital Map - Beta"
products will be supplanted by new US Topo maps and production will
continue on a national three year cycle.
US Topo maps are available on the Internet at no cost in a GeoPDF format.
Free tools allow users to determine coordinates, turn layers on and off,
zoom in and out, and print the map image. We invite you to be among the
first to evaluate this new product by visiting the USGS Store site at
store.usgs.gov. More information on US Topo can be found on The National
Map web site at nationalmap.gov/ustopo/. The site includes a
"Quickstart" user's guide, links to locate and download the available
maps, an information sheet, and some interesting information concerning
the history of topographic mapping in the USGS. Your feedback on the US
Topo is very important and will be used to improve the maps, the website,
and outreach materials. Please submit your comments via
nationalmap.gov/ustopo/ustopo_feedback.html or simply click on the
"Contact Us" tab of the US Topo web site.
Contact me if you have questions.
Best regards,
Dan
