Fenneman, N.M., and Johnson, D.W. 1946 Physiographic divisions of the conterminous U. S. map Reston, VA U.S. Geological Survey https://water.usgs.gov/lookup/getspatial?physio This is a polygon coverage of Physiographic Divisions in the conterminous United States. It was automated from Fenneman's 1:7,000,000-scale map, "Physical Divisions of the United States," which is based on eight major 1946 divisions, 25 provinces, and 86 sections representing distinctive areas having common topography, rock types and structure, and geologic and geomorphic history. 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. 19460101 Publication date of source material.

Polygon topology present. Polygon and chain-node topology present. None None. 3556 meters Resolution as reported None This coverage was automated from Fenneman's 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 U.S. boundary coverage was in Albers Equal Area Projection, the U.S. 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. 198812 Added attributes DIVISION, PROVINCE and SECTION to the polygon attribute table. 19920113 A user reported that section 23c, Southern Cascade Mountain Section was missing. Added boundary between Middle Cascade Mountain section (23b) and Southern Cascade Mountain Section (23c). Added label for Southern Cascade Mountain Section. Added annotation for 23c, Southern Cascade Mountain Section. 20020103 Vector Point 501 String 803 GT-polygon composed of chains 502 ALBERS conical equal area 29.5 45.5 -96 23 0.00000 0.00000 coordinate pair 1.0 1.0 METERS North American Datum of 1983 GRS1980 6378206.4 294.98 DATAFILE NAME: PHYSIO.PAT 9 ITEMS: STARTING IN POSITION 1 COL ITEM NAME WDTH OPUT TYP N.DEC ALTERNATE NAME 1 AREA 4 12 F 3 5 PERIMETER 4 12 F 3 9 PHYSIO# 4 4 B - 13 PHYSIO-ID 4 5 B - 17 FCODE 3 5 I - 20 FENCODE 4 5 C - 24 DIVISION 23 23 C - 47 PROVINCE 24 24 C - 71 SECTION 29 29 C - 100 PROVCODE 3 3 I - FCODE - Numeric code for physiographic section.
