The U.S. Geological Survey (USGS) has been the primary civilian mapping agency of the United States since 1879. Some of the most well-known USGS maps are the 1:24,000-scale topographic maps, also called 7.5-minute quadrangles .

There are three ways to get full-scale plots of USGS topographic quadrangle maps, including Historical Topographic maps (produced 1884-2006), US Topo maps (produced 2009-present) or customized OnDemand Topos.

scale used for most U.S. topographic mapping is 1:24,000. USGS maps at this scale cover an area measuring 7.5 minutes of latitude and 7.5 minutes of longitude and are commonly called 7.5-minute quadrangle maps. Map coverage for most of the United States has been completed at this scale, except for Puerto Rico, which is mapped at 1:20,000 and

Map Scale – The ratio of a distance on the ground to that distance represented on the printed map. The 1:24,000, (7.5 x 7.5-min) maps are the best known USGS topographic maps. There are about 55,000 map cells of this series in the 48 conterminous states, and about 127,000 individual maps.

For USGS topographic maps, 1:24,000 is the scale most often used. Maps based on metric units use a scale of 1:25,000, where one centimeter equals 0.25 kilometers. You'll find most of the United States mapped at the 1:24,000 scale, with only a few exceptions. Puerto Rico, for example, maps at 1:20,000 or 1:30,000 because the country originally ...
