The release of new US Topo maps covering Kansas and Oklahoma usher in the second round of quadrangle revisions, updates and product improvement

Last September the U.S. Geological Survey marked the important milestone of completing the initial round of US Topo map production for the 48 contiguous states. The agency is continuing to improve the US Topo map product, moving into the second round of national map revisions. Hawaii is in production and Alaska production will start later this year.

The first two states to undergo this second US Topo map revision are Kansas and Oklahoma. The 1,403 quadrangles for Kansas and 1,032 quads covering Oklahoma replace the current US Topo maps, which will be added to the USGS Historical Topographic Map Collection. All of these maps are available for free download from The National Map and the USGS Map Store website.

Other new feature additions and improvements on the updated US Topo maps include:

  • Woodland tint derived from the National Land Cover Dataset
  • Fire stations
  • Hospitals
  • State and county boundaries
  • Forest service boundaries  
  • Commercial roads in lieu of census roads
  • Forest Service roads and road numbers  

"We are excited to begin our second part of our three-year mapping cycle," said Mike Cooley, the US Topo Project Manager. "During the past year, more than 3,000 US Topo maps were downloaded every day, and that number continues to increase."

US Topos are derived from key layers of geographic data found in The National Map, which delivers visible content such as high resolution aerial photography, which was not available on older paper-based topographic maps. The new US Topo maps provide modern technical advantages that support wider and faster public distribution and on-screen geographic analysis tools for users.

Future enhancements to the US Topo are scheduled to include additional tools and map content such as a shaded relief layer, updated structures, enhanced transportation, additional federal boundaries and Forest Service trails. Wyoming, which was added in the fall of 2012, also featured Public Land Survey System (PLSS). The USGS expects to produce more than 18,500 revised quadrangles annually. US Topo maps are updated every three years.

The new digital electronic topographic maps are delivered in GeoPDF image software format and may be viewed using Adobe Reader, available as a no cost download.
