Abstract:

Topographic maps at large scale with 1 to 5 foot contour interval, covering a limited number of plant sites and industrial sites in the Tennessee Valley Region. Some are digital (Intergraph IGDS). Topographic maps at scales between 1 inch = 50 feet and 1 inch = 400 feet with contour intervals between 1 foot and 5 feet. These maps meet National Map Accuracy Standards unless otherwise specified on map sheet. Most of these maps use the State plane coordinate system, North American Datum 1927. Maps of plant sites are kept reasonably current; others are updated as needed by the agency. More recent maps are compiled using MicroStation software and Digital Elevation Model technique to produce contours. These maps are useful for the design and siting of roads, new plant facilities, and future site improvements.
