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. Limited GIS functionality, geopdf usgs quad sheets 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. The maps include layers not present on most traditional topographic maps, such as aerial photo and shaded relief images.
Many additional feature classes have been added over the life of the project, and new and better data sources have been found for others. A challenge has been finding national datasets for all the feature types of a traditional topographic map.
