Topographic maps

The United States Geological Survey (USGS), created in 1879, started systematically mapping the county in 1882. The early topographic quadrangles of the eastern United States have scales of 1:62,500 for heavily populated areas and 1:125,000 for undeveloped areas; they are more frequently referred to as 15-minute and 30-minute quads as each sheet covers either 15 or 30 minutes of latitude and longitude respectively. As the country became fully explored and better populated, USGS began mapping it at a larger scale; by the late 1950s the 15- and 30-minute series were phased out in favor of the larger-scale 7.5 minute series (1:24,000). USGS also maps the US at smaller scales that show less detail but cover larger areas.

The Map and Government Information Library holds both current and old editions of USGS topographic maps for all states and US territories (American Samoa, Guam, Puerto Rico, the Northern Mariana Islands and the US Virgin Islands) at some or all of the following scales:

  • 1:24,000 (7.5-minute)
  • 1:63,360 (Alaska 15-minute)
  • 1:100,000 (30 x 60-minute)
  • 1:250,000
  • Historical 15-minute (1:62,500), 30-minute (1:125,000) & specials (scales vary)
  • Topographic map symbols for USGS maps
