Alaska has partial coverage, which is expected to be completed in 2022. Hawaii, Puerto Rico, and US Virgin Islands also have US Topo coverage. The third cycle is planned for completion in 2018. The first 3-year production cycle for the conterminous 48 states was completed in September 2012, and the second in September 2015. US Topo maps are produced by the USGS National Geospatial Technical Operations Center. See this FAQ for more information about specific layers. A challenge has been finding national datasets for all the feature types of a traditional topographic map. Many additional feature classes have been added over the life of the project, and new and better data sources have been found for others. The maps include layers not present on most traditional topographic maps, such as aerial photo and shaded relief images. Limited GIS functionality, such as displaying ground coordinates, is available with all maps, and the layered construction of the PDF files allows users to turn data layers on and off. All maps can be viewed and printed with Adobe Reader or comparable PDF viewing software.

US Topo maps can be downloaded free of charge from several USGS websites. US Topo maps repackage geographic information system (GIS) data in traditional map form this benefits non-specialist map users, as well as applications that need traditional maps. These maps are modeled on the familiar 7.5-minute quadrangle maps of the period 1947-1992, but are mass-produced from national GIS databases on a repeating cycle. The project was launched in late 2009, and the term “US Topo” refers specifically to quadrangle topographic maps published in 2009 and later. US Topo topographic maps are produced by the National Geospatial Program of the U.S. Building on the success of more than 130 years of USGS topographic mapping, the US Topo series is a new generation of maps of the American landscape.
