This is an ESRI feature class showing boundaries for physiographic divisions in Illinois. Data are originally from ISGS Report of Investigations 129 by Leighton et al., 1948. The physiographic divisions of Illinois are divided into the following: Provinces, Sections, and Divisions. (The annotations are in the companion shapefile IL_Physio_Regions_1993_Anno_Ln). Scale is 1:3,00,000 to 1:3,100,000.

This data set records information about the physiographic divisions of Illinois. The data set was digitized so that it could be included as an inset map on the 'Shaded Relief Map of Illinois', ISGS OFS 1995-6, reissued as IMAP 6.
