No, US Topo products are derived from GIS data and packaged in traditional map form for the benefit of non-specialist users. Most of the data used to make these products are available from USGS through map services and staged datasets. USGS map services include a topographic base map service, USGSTopo, that is a close approximation of traditional topographic map presentation at larger scales, and is built from many of the same sources as US Topo, but is designed for GIS use.
