Title Stearns County Geologic Atlas, Part B
Abstract Export files and shapefiles of Arc/INFO coverages depicting a variety of characteristics of the ground-water system of Stearns County, Minnesota.
Purpose Geographic information systems (GIS) layers were created to cartographically depict and spatially analyze data used in the production of the Stearns County Geologic Atlas, Part B.

A County Geologic Atlas (CGA) is a systematic study of a county's geologic and ground-water resources. Geologic studies include both near-surface deposits and bedrock. Ground-water studies include flow systems, aquifer capacity, ground-water chemistry, and sand and gravel deposits.

Interpretation of sensitivity to pollution is also part of a CGA. The information is organized, analyzed, and displayed using GIS technology.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy
Logical Consistency Data are topologically correct using ARC/INFO 7.1.1
Completeness Complete
Horizontal Positional Accuracy
Lineage Review of available data:
Investigations begin with a review of existing information, such as earlier geologic maps, soil maps, hydrologic reports, and information provided by well drillers. Drillers send water well logs to the Minnesota Geological Survey, where they are reviewed, interpreted, and entered into the County Well Index (CWI), an interactive data base of water-well information.

Collection of data from the field:
Field studies are conducted to measure static water level elevations and chemistry of selected wells. These studies, combined with pre-existing data, are used to create models of water-table and bedrock hydrogeology (elevation, potentiometric surface, potential yield, flow direction), and sensitivity of ground water system to pollution.

Creation of GIS layers:
Using a variety of techniques, data is converted into Arc/INFO coverages or ARCVIEW shapefiles for cartographic display and spatial analysis.

COVERAGES USED IN PLATE 8: Hydrogeology of the Water-Table

1. Minnesota Dept. of Transportation soil boring locations
2. Flow direction of the water table
3. Seismic sounding locations
4. United Power Association soil boring locations
5. Water table elevation contours
6. Potential yield of the water table

COVERAGES USED IN PLATE 9: Hydrogeology of Bedrock Aquifers

1. Buried sand and gravel deposits
2. Cretaceous aquifer
3. Flow direction of Cretaceous aquifer
4. Flow direction of Precambrian aquifer
5. Flow direction of Quaternary buried aquifers
6. Potentiometric surface of the Cretaceous aquifer
