Illinois State Geological Survey 1993 20040423 vector digital data ISGS GIS Database GISDB_QTGEO.IL_Physiographic_Regions Champaign, Illinois Illinois State Geological Survey http://www.isgs.illinois.edu/ http://illinois.edu 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. Central Lowland Province Ozark Plateaus Province Interior Low Plateaus Province Coastal Plain Province Wisconsin Driftless Section Great Lake Section Till Plains Section Dissected Till Plains Section Lincoln Hills Section Salem Plateau Section Shawnee Hills Section Rock River Hill Country Wheaton Morainal Chicago Lake Plain Green River Lowland Kankakee Plain Galesburg Plain Bloomington Ridged Plain Springfield Plain Mt. Vernon Hill Country 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. The data are not appropriate as a geodetic, legal or engineering base. The data set was not and is not intended as a substitute for surveyed locations, such as can be determined by a registered Public Land Surveyor. Although useful in a GIS as a reference base layer for maps, the data set has no legal basis in the definition of boundaries or property lines. Recent updates to the data: In April 2004 edition 1.1 of the data set was transitioned to storage in an Oracle RDBMS using the ArcSDE geodatabase model. The result was designated Edition 20040423. This shapefile was generated from that edition. The provinces, sections, and divisions are labeled with annotation as most of the areas are not closed polygons (within Illinois). Refer to the companion JPEG image for a visual suggestion of how to best display the annotation. 1948 publication date of source Complete None planned -91.452685 -87.437114 42.568874 37.102418 none Physiographic Division Divisions Province Provinces Section Sections Plain Plains geology geologic geomorphology geomorphologic none Illinois ISGS information must be obtained directly from the ISGS or from an authorized distributor.

No report. This is an accurate representation of the Leighton et al. (1948) map. Horizontal positional accuracy is verified by visual comparison of source and hard copy plots to be within one line-width. See sources for a determination of the accuracy of source materials. These are generalized boundaries of gross physiography in Illinois and are not intended to represent sharp lines of transition from one area to the next. Leighton, M. M., G. E. Ekblaw, and L. Horberg 1948 map ISGS Report of Investigations 129 Champaign, Illinois Illinois State Geological Survey 3000000 paper 1948 publication date RI 129 Source map was a photocopy of an original 1:3,000,000 map (Figure 1). Source contributed lines and physiographic division names. Originally digitized in November, 1993. Arc topology present. Source map was a photocopy of an original 1:2,000,000 map (Figure 1, RI 129). Tics at county intersections were used as registration points. 1993 Data set was reviewed in May, 1998. Review was limited to internal logical consistency of attribute items. Locations of features and accuracy of item values were not checked, except in cases where possible errors became apparent as a result of logical consistency checks. No checks were performed that involved plotting of hardcopy maps and manual overlay with source materials. Some changes were made, as follows: Values indicating line type were stored in the cover-id. A new item called SYMBOL was added the values to that item. The cover-ids were recalculated to be unique. 199806 Source coverage (physio) converted to double precision and reprojected to GCS_NAD83 using Workstation ArcInfo 7.2.1. The features were imported into the ISGS SDE enterprise database following steps outlined in ISGS procedure GISDB_0009.
