This is a Vector data set. It contains the following vector data types (SDTS terminology):
The map projection used is Lambert Conformal Conic.
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest unknown
Ordinates (y-coordinates) are specified to the nearest unknown
Planar coordinates are specified in feet
The horizontal datum used is NAD27.
The ellipsoid used is CLARKE1866.
The semi-major axis of the ellipsoid used is 6378206.4 meters.
The flattening of the ellipsoid used is 1/294.98.
1 - plunging anticline or anticlinal nose 2 - doubly plunging anticline 3 - asymmetrical anticline 4 - monocline 5 - syncline 6 - anticline (unspecified type)GEOHORIZON and GEOHORIZON2 indicate the names of the geologic formation on which the feature is mapped. The ISGS Geologic Formation Numbering Code, a unique four digit number, was used to indicate these designations. If no horizon is indicated a code of 9999 is entered, meaning that the feature was mapped at the surface. In some cases there is more than one geologic formation associated with a mapped structural feature; in this case the GEOHORIZON2 field is used to indicate the additional geologic formation code number.

The published (Plate 1) map from ISGS Bulletin 100 was the source for feature attributes. Attribute code assignments were checked by three individuals and are believed to fully representative of the source document.
The horizontal positional accuracy of this data with respect to the source map was verified by three individuals by visual comparison (manual overlay) of source maps and hard-copy plots. Arcs within one line-width of source mylars were deemed acceptable. Consult the sources for information on the derivation of structure locations.
This data set contains anticlines, synclines and monoclines shown as line features on Plate 1, ISGS Bull. 100. For other structural features, see the related data sets STRUCTFAULTS, STRUCTPNTS and STRUCTPOLY. These four data sets together show all well documented significant structures in Illinois as defined by ISGS Bull. 100.
Chain-node topology is present. This data set was checked for complete chain-node topology (no dangling arcs, except where appropriate), boundary values appropriate for map projection and map units, and appropriate "fuzzy" tolerances. There are no known arc attribute values outside the appropriate value domains.
Are there legal restrictions on access or use of the data?
