Description Abstract This is a polygon coverage of Physiographic Divisions in the conterminous United States. It was automated from Fennemans 1:7,000,000-scale map, "Physical Divisions of the United States," which is based on eight major divisions, 25 provinces, and 86 sections representing distinctive areas having common topography, rock types and structure, and geologic and geomorphic history. Descriptors: Physiographic Divisions Physiographic Provinces Physiographic Sections Purpose The primary use of this data is for regional and national data display rather than specific local data analysis due to the small scale (1:7,000,000) of this coverage. Supplemental_Information Procedures_Used This coverage was automated from Fennemans 1:7,000,000-scale map, "Physical Divisions of the United States", 1946. Features were digitized from a stable mylar base into the United States boundary coverage. Since the map is in polyconic projection, and the US boundary coverage in Albers Equal Area Projection, the US boundary coverage was first projected into polyconic projection before digitizing. Once digitizing was complete, the coverage was projected back into Albers Equal Area Projection, with the following parameters: First parallel 29 30 00 N Second parallel 45 30 00 N Central meridian -96 00 00 W Latitude of projection origin 23 00 00 N False easting 0.0 False northing 0.0 Fennemans map is missing three boundaries separating: 1. 5a/5b (which separates the Northern and Southern sections of Blue Ridge) 2. 6a/6b (which separates Tennessee and Middle sections of Ridge and Valley) 3. 24b/24c (which separates Olympic Mountains and Oregon Coast Range of the Pacific Border province) These boundaries were researched, then merged into the coverage. Revisions 1.0 12/88 Coverage generated. 1.1 01/13/92 Added attributes division, province and section to PAT. Reviews_Applied None.
