“US Topo Quadrangles – Maps for America” – US Geological Survey

“US Topo topographic maps are produced by the National Geospatial Program of the U.S. Geological Survey (USGS). The project was launched in late 2009, and the term “US Topo” refers specifically to quadrangle topographic maps published in 2009 and later. 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. 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.

“US Topo maps can be downloaded free of charge from several USGS interfaces. The maps are published in Portable Document Format (PDF) with geospatial extensions (GeoPDF®). They can be viewed and printed with Adobe Reader or comparable PDF viewing software. The geospatial extensions provide limited GIS functionality, such as displaying ground coordinates and measuring distances and areas. Layered PDF files allow users to turn data layers on and off. The maps include layers not present on most traditional topographic maps, such as aerial photo and shaded relief images.”
