Topographic maps are used to convey three-dimensional land elevations on a two-dimensional surface. They are often used for engineering, energy exploration, natural resource conservation, cultural resource management, environmental management, public works design, commercial and residential planning, and outdoor activities like hiking, camping, and fishing. The University of Tennessee is digitizing its collection of out of print 7.5 minute topographic maps making them more easily accessible for research, teaching and general use.   Note: The Search Option is under construction
