The United States Geological Survey (USGS) is responsible for creating and maintaining topographic maps of all states in the US. These maps provide detailed information about the landscape, including elevation, trails, bodies of water, and land use.
Topographic map
The United States Geological Survey uses the same legend on all of their maps to avoid confusion when looking at different maps. If one map used one symbol for a specific geologic type of marker and another map used another symbol, it would be extremely difficult to read the maps quickly and efficiently.
topographic maps have contour lines that show a specific place...
The United States Geological Survey (USGS) is the government agency that produces and distributes topographic maps. These maps provide detailed information about the terrain, elevation, and natural features of a specific area. Topographic maps are commonly used by a variety of government agencies, such as the Department of Interior and Department of Agriculture, as well as by outdoor enthusiasts, land planners, and emergency responders.
