Alabama State Topo Map The United States Geological Survey (USGS) publishes maps in non-quadrangle format. These maps include; a county map series, State base map series, U.S. base maps, a National Park series, and outline maps of the World. Scales range from 1:960 to 1:80 million. Data categories are increasingly generalized as the map scales become smaller. These maps provide data on boundaries, hydrography, Public Land Survey System, transportation, manmade structures, hypsography, vegetative and non-vegetative surface cover (e.g., woods, orchards, lava, sand), geographic reference systems, geographic names, bathymetric contours (in coastal areas). No hypsography data is included in planimetric editions.
