US Topo Update: Production and release of the US Topo started in October 2009. The US Topo is an enhancement of the previous "Digital Map–Beta" product, with the addition on the hydrography and contour layers. The new mapping product was formally introduced at the "125th Anniversary of Topographic Mapping" Celebration on December 3, 2009. The National Geospatial Technical Operations Center reports the following:
- More than 2,887 US Topo maps are loaded to the Map Locator of the USGS Store (as of 03-05-10)
- Kansas is the first US Topo state, and is currently more than 90% complete (more than 1335 quadrangles) and will be followed by:
- Oklahoma: 92% complete (975 quadrangles)
- New York: 30% complete (289 quadrangles)
- Texas: 7% complete (288 quadrangles)
- Kentucky
Digital Map–Beta Update: In a little less than nine months since the release of the "Digital Map–Beta" web site, the National Geospatial Technical Operations Center can report the following:
- More than 14,346 "Digital Maps–Beta" are loaded to the Map Locator of the USGS Store
- State quad status, in order of loading to the Map Locator: (as of 03-05-10)
- Arizona: 100% complete
- California: 98% complete
- Louisiana: 100% complete
- Nebraska: 100% complete
- Wyoming: 99% complete
- Alabama: 100% complete
- Nevada: 86% complete
- Mississippi: 91% complete
- Maine: 99% complete
- South Dakota: 100% complete
- Illinois: 99% complete
- Missouri: 100% complete
- New Hampshire: 96% complete
- Vermont: 100% complete
- Rhode Island: 100% complete
- Florida: 98% complete
- Connecticut: 100% complete
- Massachusetts: 100% complete
Note: Forest Service quads in the above states are currently not included, which often gives a "missing quad" look. The USGS is working with the Forest Service so that maps made in 2010 and beyond will include lands administered by USFS.
The "Digital Map–Beta" is the initial electronic digital map. With the integration of the hydrography and contour layers, the maps produced after October 2009, and starting with Kansas, will be classified as US Topo.
