Detailed Description
This graphic represents the planned US Topo map production schedule for the next three- year revision cycle. The US Topo project repackages data from national GIS (geographic Information system) databases as traditional maps, primarily for the benefit of non-GIS users. Unlike traditional topographic maps, US Topo maps are mass-produced from secondary sources, on a programmed refresh cycle, using the best available data at the time of production.
