USGS 100K Topos are now fully available in the topoBuilder application!
These are the first USGS topographic maps produced at the 1:100,000 scale in over 30 years and continue the legacy of USGS topographic mapping.
100K Topos cover a much larger area than the 1:24,000 scale, 7.5-Minute Topo maps that have been available since OnDemand Topos became an official USGS product, but still provide plenty of geospatial context for many recreational, science, and planning applications. The 100K Topo map content is from The National Map, and all OnDemand Topos are available on a free and unlimited basis.
