How current are US Topo maps?

US Topo maps are remade every three years. The US Topo production schedule follows the U.S. Department of Agriculture's National Agricultural Imagery Program (NAIP) collection schedule. The linework features shown on the maps are generated from the latest data holdings in The National Map and other standard sources. The overall goal of the project is for each map to be current to within three years at the time of publication, though there is considerable variation in actual feature currency due to the variety of data sources used and their varying revision schedules.

How accurate are US Topo maps, and why don't they have an accuracy statement?

US Topo maps are as accurate as the data sources used to make them, but because these sources are many and varied, it is not possible to make a single simple statement that the map as a whole meets a particular level of accuracy. US Topo maps, therefore, do not have a traditional accuracy statement in the map collar. Accuracy information for...

How do US Topo maps differ from historical USGS topographic maps?

Historically, USGS topographic maps were made using data from primary sources including direct field observations. Those maps were compiled, drawn, and edited by hand. By today's standards, those traditional methods are very expensive and time-consuming, and the USGS no longer has funding to make maps that way. A new USGS topographic map series...
