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.In 2009, the USGS transitioned from our hand scribed historical topographic maps to US Topos, which are computer-generated on a regular schedule using national databases ...

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. The difference between 55,000 cells and the 127,000 printed maps in the HTMC is due to reprints, revisions, and variant editions.

The maps shown through topoView are from the USGS’s US Topo series and earlier Historical Topographic Map Collection (HTMC). The term “US Topo” refers specifically to quadrangle topographic maps published in 2009 and later. These maps are modeled on the familiar 7.5-minute quadrangle maps of the period 1947-1992, but are mass-produced ...

Each map covers all or part of one wilderness area and the scale is generally 1 inch per mile (1:63,360). Topographic Maps. FSTopo is the Forest Service series of large scale topographic maps. FSTopo maps are 7.5 minute, 1:24,000-scale over the conterminous United States, and 15 minute X 20-22.5 minute, 1:63,360-scale over Alaska.

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 ...

This layer presents the geographic extent of USGS 1:24,000 scale topographic maps (7.5- by 7.5-minute quadrangles) for the conterminous U.S. 48 states and District of Columbia. It provides quadrangle name, identification number, publication data, and map coverage by state for each quadrangle. This large-scale index grid is appropriate for ...
