Title: Glacial Drift Aquifer
Description:
Abstract: These digital maps contain information on the altitude of the base, the extent, and the potentiometric surface (i.e. altitude of the water table) of the Glacial-drift aquifer in Kansas. The Glacial-drift aquifer consists of surficial sand and gravel deposits as well as sand and gravel buried beneath unconsolidated till and loess of Pleistocene age. The bedrock digital map was developed from 1:125,000-scale source information with a contour interval of 50 feet. The extent map was developed from 1:500,000-scale source information. Included as part of the digital extent map are areas where older rocks crop out within the aquifer boundary (fensters) and areas where the glacial-drift aquifers have little or no saturated thickness. The potentiometric surface digital map was developed at a scale of 1:200,000- from water-level data collected and compiled by the Kansas Geological Survey and from data available from the U.S. Geological Survey's National Water Information System (NWIS). The potentiometric surface contour interval is 50 feet. These digital maps were produced in cooperation with the Kansas Water Office as part of the State Water Plan.
Purpose: These digital maps were developed to be part of a multi-layer digital data base for the major aquifers in Kansas. Potential uses of these digital maps include studies addressing the location, quantity, quality, management of ground-water resources in Kansas.

Data_Quality_Information:
Logical_Consistency_Report:
Datasets delivered to the Data Access and Support Center are quality assurance tested for major documentation and topological errors using macros. The databases are evaluated based on questions similar to the following:
Does the database's documentation properly explain the dataset? Does the data import properly into its native dataset environment? Is consistent methodology used throughout the data? Are all of the database's fields and values legitimate compared to the documentation? Is the database's topology free of errors that could impair the functionality of the data? Once the data is tested a report is written describing the evaluation. A copy of the report is then forwarded to the data originator for his/her review. If errors are found, the data originator is expected to make any necessary corrections and then provide those corrected coverages. After these steps have been taken data is considered archivable and made available for distribution. Data that is archived by DASC has been tested and corrected.

A total of 8 DXF files each provided information for one or more counties in the glacial-drift area of northeast Kansas. Counties for which bedrock information was available include the following: Atchison, Brown, Doniphan, Douglas, Jackson, Jefferson, Johnson, Leavenworth, Nemaha, Shawnee, Wabaunsee, and Wyandotte. Counties for which no bedrock information was available include Marshall, Pottawatomie, Riley, and Washington. The individual DXF files were converted to digital maps using the DXFARC subprogram within ARC/INFO. Each digital map was editied (to fix broken contours, remove overshoots, extend undershoots, etc.) using the ARCEDIT subprogram within ARC/INFO. Line topology then was built using the BUILD subprogram within ARC/INFO. A master tic digital map was developed for the entire area using the coordinate information for township corners obtained from the statewide township digital map (available from the State GIS Data Access and Support Center (DASC)). The master tic digital map was projected into Lambert Conformal Conic projection (with the parameters that have been approved as a standard by the Kansas State GIS Policy Board) using the PROJECT subprogram within ARC/INFO. The individual digital maps then were edited so that each digital map had tics that corresponded to the tics in the master digital map in terms of the tic i.d. numbers. The digital maps then were transformed to convert from scanner units to Lambert Conformal Conic units (meters) using the TRANSFORM subprogram within ARC/INFO. Next, the digital maps were rubbersheeted to align with the statewide township digital map and a statewide county digital map (also available from DASC) using the ARCEDIT subprogram within ARC/INFO. ARCEDIT was used subsequently to attribute the contour lines, edgematch the digital maps, and remove all county and township lines. Finally, the individual digital maps were joined together using the APPEND subprogram within ARC/INFO. Line topology was built for the resulting digital map using the BUILD subprogram within ARC/INFO. The digital map then was clipped to the boundary of the glacial-drift aquifers using the CLIP subprogram within ARC/INFO. Following the clip, line topology was rebuilt. The digital map of the boundary of the glacial-drift aquifers (that was used to perform the clip) was developed from several sources (Denne and others, 1991; Hansen, 1991; Ross, 1991) and is also available from DASC. Because bedrock information was not available for the entire glacial-drift aquifers area, a total of 62 dangle nodes are present in the digital map. The dangle nodes are not errors but simply due to the inavailability of the additional information required to extend the contour lines to the boundary of the aquifer. Process_Date: 1995 Process_Step: Process_Description: The digital map of the extent of the glacial-drift aquifers was developed from the digital surficial geology map of Kansas (Ross, 1991) and the map showing saturated thickness of the glacial-drift aquifers by Hansen (1991, plate 1). The areas of little or no saturated thickness were developed from well data compiled and collected by the Kansas Geological Survey (Denne, et al., 1990) and available from the U.S. Geological Survey's National Water Information System (NWIS). Modifications to the digital map were made using the ARCEDIT subprogram of ARC/INFO. The digital map is projected in the Lambert Conformal Conic projection with the parameters that were approved as a standard by the Kansas State GIS Policy Board. Process_Date: 1995 Process_Step: Process_Description: The digital map of the potentiometric surface (i.e., altitude of the water table) of the glacial-drift aquifers was developed from water-level data collected and compiled by the Kansas Geological Survey (KGS) (Denne and others, 1990) and available from the U.S. Geological Survey's National Water Information System (NWIS). Only water-level data collected and compiled by KGS (Denne and others, 1990) from wells within the extent of the glacial-drift aquifers, or from wells in NWIS that were coded as obtaining water from geohydrologic units equivalent to the glacial-drift aquifers, were used in development of this digital map. Because insufficient data were available to develop the potentiometric surface map for a single year, mulit-year data were used. The location of the wells were converted to decimal degrees of latitude and longitude from modifications of the Bureau of Land Management's system of land subdivision (township, range, section, and section subdivisions) using the LEO computer program (Ross, 1989) or from degrees, minutes and seconds of latitude and longitude. The well locations in decimal degrees were entered into the ARC/INFO Geographic Information System (GIS) and then projected to the Lambert Conformal Conic projection (with the parameters that have been approved as a standard by the Kansas State GIS Policy Board) using the Project subprogram of ARC/INFO. The water-level data were plotted by machine at a scale of 1:200,000 on mylar and then contoured by hand. The map of the altitude of the bedrock surface (base of the glacial-drift aquifer) (Denne and others, 1991 (in press)), as well as U.S. Geological Survey 1:100,000-scale topographic quadrangle maps, were used to guide the placement of the water-level contours. The hand-drawn contours then were digitized manually using the ARCEDIT subprogram of ARC/INFO. Due to insufficient information, two water-level contours terminate before intersecting the boundary of the aquifer. Thus, there are two dangle nodes in the digital map that are not considered errors. The contours were attributed using the ARCEDIT subprogram of ARC/INFO and then checked for completeness and consistency.

The gd_base.aat, gd_extent.aat, and gd_potent.aat contain two items named ALTITUDE_FEET and CODE. The gd_extent.pat has a CODE item. The following is a brief definition of each item: ALTITUDE_FEET-This item describes the altitude of the bedrock surface (in feet; datum is sea level) for the gd_base coverage, the altitude (in feet) for the gd_extent coverage, and the altitude of the potentiometric surface (in feet; datum is sea level) for the gd_potent coverage. CODE-This item contains a 3- or 4-digit number that indicates the type of feature represented (e.g., contour, fault, boundary), the confidence in the feature's location (i.e., approximate, inferred, speculative), and the cartographic symbol with which the feature is displayed (e.g., continuous line, dashed line) for the gd_base, gd_extent, and gd_potent coverage. For the gd_extent.pat, the CODE item is used for a 1-digit code indicating the type of area represented by the polygon.
