Nebraska Statewide Test-hole Database Retrieval System
Introduction
The Nebraska statewide test-hole database contains information for about 5,500 test holes drilled since 1930 by the Conservation and Survey Division (CSD), School of Natural Resources (SNR), University of Nebraska, and cooperating agencies. Test-hole location data, as well as lithologic descriptions, stratigraphic interpretations and geophysical log records are included in the database. In addition, CSD/SNR maintains an extensive collection of geologic samples obtained from the drilling process.
The retrieval system is designed so that the user may extract and download only the data that is desired. During the download process, several files may be created and made available to the user to transfer to their computer. An option is also provided to download the entire test-hole database.
Instructions
The first step in the process of retrieving information from the test-hole database is to select location criteria and enter the required parameters. Either a county or a natural resources district is selected by using the provided dropdown boxes. Regions may be designated by latitude and longitude (enter the latter as a positive number; the negative sign is provided) ranges or by selecting a range of township and range values. Once the appropriate parameters have been entered, the corresponding Submit button is pressed. A listing of test holes within the selected location area will be displayed in the lower left table. The user may then select either all or part of the list to add to the table on the right. At this point, the user may view the information corresponding to the selected test holes by pressing the Show Selected Test Hole Information button. From this page, the user may download the test-hole data as delineated-text files or may return to the previous page to either add more test holes to the selected dataset or to begin a new search.
