    There are reasons to believe that the overall accuracy of the US Topo series is very good. High-accuracy geospatial data is increasingly common, mostly due to Global Positioning System (GPS) technology. The orthoimage layer in US Topo maps is derived from images of the National Agriculture Imagery Program (NAIP). The production of these images ...

    Feb 13, 2019 · This map product series, named “US Topo,” is modeled on the now historical USGS 7.5-minute (1:24,000 scale) topographic map series produced and printed by the USGS from 1947 to 2006. US Topo maps have the same extent, scale, and general layout as the historical topographic maps.

    The goal in US Topo map production is to construct a geospatial PDF that strikes a balance between manageable file size and visual quality. The orthoimage has the greatest effect on file size. Government-procured orthoimagery is typically collected at a ground sample distance (GSD) between 6 inches and 1 meter.

    The US Topo series are the current generation of USGS topographic maps. The first of these maps were published in 2009. They are modeled on the legacy 7.5-minute series of the mid-20th century, but unlike traditional topographic maps they are mass produced from GIS databases, and are published as PDF documents instead of as paper maps.
