What are the USGS's plans for the topographic maps?

After the completion of the original 7.5-minute map series in 1992 and until late 2008, the USGS mapping program focused on creating national geographic information system (GIS) databases. In November 2008, USGS management committed to design and produce a new digital quadrangle topographic map series, branded as US Topo in 2010.

Topographic maps produced between 1884 and 2000 were all printed paper maps.  These were recently scanned and are published in PDF as historical documents.  See Historical Topographic Maps- Preserving the Past for more information.
