Scott County Geologic Atlas

Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Minnesota Geological Survey
Abstract A County Geologic Atlas 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, and ground water chemistry. In some areas sand and gravel deposits, sinkholes, or other features are studied. Interpretation of sensitivity to pollution is also part of an atlas. The information is organized, analyzed, and displayed using geographic information technology.

The Scott County Geologic Atlas contains the following plates:
Plate 1: Database Map
Plate 2: Bedrock Geology
Plate 3: Surficial Geology
Plate 4: Quaternary Stratigraphy
Plate 5: Bedrock Topography, Depth to Bedrock, and Bedrock Geology Models
Plate 6: Subsurface Recharge and Surface Infiltration

Typically Minnesota Geologic Atlas projects are done in two parts. Part A covers basic geology and creates databases of primary source information such as wells and soil borings. Part B covers hydrogeology and ground water sensitivity. Some ground water sensitivity-related information is covered in Plate 6 of this atlas. There will be no Part B for the Scott County Geologic Atlas.

Purpose County Geologic Atlas and Regional Hydrogeologic Assessment information is used in planning and environmental protection efforts at all levels of government. Wellhead protection and well-sealing programs are examples of local programs that need geologic and ground water information. The information is also used by businesses and the general public.

Attribute Accuracy See individual layer metadata files on ftp site.
Logical Consistency See individual layer metadata files on ftp site.
Completeness See individual layer metadata files on ftp site.
Horizontal Positional Accuracy See individual layer metadata files on ftp site.
Lineage Investigations begin with a review of existing information, such as earlier geologic maps, soil maps, and hydrologic reports. 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. Building on the previous data, field studies are conducted to improve the understanding of local geologic and hydrologic conditions. Linework is created based upon the field studies and base data, and digitized. See also individual metadata reports at ftp://mgssun6.mngs.umn.edu/pub3/c-17/c-17meta/
