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.
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.

Map information is to be used at a scientifically and cartographically appropriate scale, that is, at a scale no greater than indicated on the map or as described in the documentation of the map or map data. Map information is not appropriate for, and is not to be used as, a geodetic, legal, or engineering base. Map information has no legal basis in the definition of boundaries or property lines and is not intended as a substitute for surveyed locations such as can be determined by a registered Public Land Surveyor.
The data do not replace the need for detailed site-specific studies.
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.
The features were imported into the ISGS SDE enterprise database following steps outlined in ISGS procedure GISDB_0009.
Metadata updated.
Arc attributes: SYMBOL - Defines line thickness, which in turn divide the various regions: 9 - Thick line, separates major physiographic provinces 5 - Medium weight line, separates physiographic sections (within provinces) 1 - Thin line, separates physiographic divisions (within sections)
Annotation Attributes: Physiographic division names are indicated by annotation (labels) in the companion shapefile IL_Physio_Regions_1993_Anno_Ln. Provinces, Sections, and Divisions included are:
