Types of current topographic maps
US Topo is the current USGS topographic map series for the Nation. These are modeled on the legacy 7.5-minute maps, but are mass-produced from GIS databases of The National Map and published as digital documents.
OnDemand Topos are USGS-style topographic maps created using the topoBuilder application. These maps are generated upon request using the best available data from The National Map and offer customizations such as choice of format, area of interest, and National Map content.
