Databases of geologic information on CD-ROM—wiscLITH and TILLPRO

The Wisconsin Geological and Natural History Survey is pleased to announce the availability of two digital databases containing a wealth of geologic information for the state.

One database, called wiscLITH, has been gleaned from nearly 45,000 paper records that are maintained by the Survey and contains detailed descriptions of rock types (including stratigraphy and lithology) encountered during well drilling. We will release an updated set of data files twice a year, during the first week of January and the first week of June.

The other, called TILLPRO, is primarily a database of grain-size analyses performed on unlithified sediment samples collected from Wisconsin and analyzed in the Quaternary Laboratory at the Department of Geology and Geophysics, University of Wisconsin-Madison. TILLPRO was released in 2008.

In both databases information is organized in a set of related tables in Microsoft® Access® format. Forms and queries allow a user with rudimentary database skills to view, sort, select and evaluate the information; users can perform searches on the records and customize the format for their particular use or interpretation. Records can be selected and exported to other software programs for further analysis. In addition, the wiscLITH CD-ROM includes software that enables the user to bring the subsurface records into a geographic information system for further analysis.

The wiscLITH and TILLPRO databases will be useful to planners, environmental consultants and regulators, water-supply engineers and drillers, and earth-science researchers.

The databases are available separately; each CD-ROM can be purchased for $25 from the Map Sales office of the Wisconsin Geological and Natural History Survey, 3817 Mineral Point Road, Madison, Wisconsin 53705-5100. MasterCard and Visa customers may telephone their orders (608/263.7389) between the hours of 8 am and 4:30 pm, Monday through Friday. Shipping and handling charges are extra; refer to our order form, which is in Adobe® Acrobat® format.
