Digital Topographic Map Series

Submitted by Anonymous (not verified) on

US Topo is the new generation of digital topographic map series from the U.S. Geological Survey (USGS). Arranged in the traditional 7.5-minute quadrangle format, US Topo maps allow faster and wider public distribution along with basic, on-screen geographic analysis for all users. US Topo maps use U.S. Department of Agri­culture 1-meter ground resolution orthoimagery from the National Agriculture Imagery Program (NAIP). The NAIP orthoimagry layer provides a nationally consistent geographic visual context to the symbolized layers of the map. US Topo maps are available for free download as a GeoPDF from the USGS Map Locator and currently cover the entire continental U.S.
