Areas that contain sinkholes are susceptible to aquifer contamination and may also lack the stability required for certain land-uses. Sinkholes are one of the major indicators of karst terrains. This map provides basic data for land-use planning and decision making. Purpose: Sinkhole data can be used to appraise local, regional, and general geologic conditions that might affect excavation and construction of roads, pipelines, foundations, and sewers, and construction of wells. These sinkhole data are useful for local planning of surface projects which may have an impact on shallow aquifers. The data are useful for regional land-use planning projects designed to protect shallow karst aquifers. This map may be useful for the exploration and exploitation of limestone. Karstification may have an effect on the evaluation of limestone resources and an impact on the groundwater during limestone extraction. These data are appropriate for use in regional thematic analysis. The data are not appropriate as a geodetic, legal or engineering base. The datasets were not and are not intended as a substitute for surveyed locations, such as can be determined by a registered Public Land Surveyor. Although useful in a GIS, the data have no legal basis in the definition of boundaries or property lines. Supplemental_Information: This is edition 20040408, derived from edition 2.0. In April 2004 the source coverage was transitioned to storage in an Oracle RDBMS using the ArcSDE geodatabase model. The result (this version) is designated edition 20040408. Prior to this time the feature classe was stored as a coverage in the ISGS GISDB archive. Edition 2.0 differed from edition 1.0 in that some sinkhole polygons in northwestern Illinois were deleted after field examination suggested that the depressions may have an origination other than by sinkhole formation. In addition, additional sinkhole area polygons were added in southern, southwestern, and western Illinois.

Logical_Consistency_Report: When this data set was in coverage form it 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 or polygon attribute values outside the appropriate value domains. Completeness_Report: This data set contains polygons indicating areas which are believed to contain sinkholes. Some sinkholes may not be represented on this map because of detection problems (primarily because of too small of a size, and dense vegetation cover). Not every sinkhole polygon was field checked. Therefore, it is possible that some depressions within the mapped polygons may have an origin different from sinkhole formation. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Boundaries of sinkhole area polygons represent actual ground positions, but are generalized. Thus, this data set should not be used at map scales larger than 1:100,000 without specific field verification.

Process_Date: Unknown Process_Step: Process_Description: Reviews of data. Source map underwent ISGS peer review. Line accuracy was checked by overlay of digital print-outs to original compilation maps. Lines within one line-width of source maps were deemed acceptable. Attribute accuracy was verified against source maps. Process_Date: 1994-95 Process_Step: Process_Description: The source coverage (karst) was imported into an ArcSDE enterprise geodatabase feature dataset for storage. Previously it was stored as individual coverages. The data were reprojected from the customary ISGS Lambert Conformal Conic projection (NAD27) to a geographic coordinate system (longitude, latitude) in decimal degrees (NAD83). Prior to import, the spatial reference of the data set was changed to Geographic, decimal degrees, NAD83 in double precision. Also at this time, this metadata file was updated.
