Benton County Geologic Atlas - Part A

This page last updated: 05/27/2011
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.

Most Geologic Atlas and Regional Hydrogeologic Assessment projects are done in two parts. The Minnesota Geological Survey covers basic geology and creates databases of information such as wells and soil borings in part A. The Minnesota Department of Natural Resources handles hydrogeology and ground water sensitivity layers in Part B. Completion of a project's two parts is staggered: Part A is completed about two years before Part B, compiling information used to create part B. Parts A and B are published and distributed as two separate products.

Ordering Instructions All digital data for the Benton County Geologic Atlas is provided in the zip file C23_cd.zip. The title refers to the CD/DVD available from MGS where the data is formatted into ArcGis projects. However, the projects are available within the zip file as well. If you would prefer to have the digital data on DVD, contact MGS Map Sales Department at (612) 627-4780, ext. 238.

PDF files representing map plates and metadata for data layers are available on the ftp site, as well as a README file describing the contents. The pdf maps should be viewed using Acrobat Reader 5.0 or higher for best \results. If necessary, download the files in binary, not ASCII.

If you would like paper copies of the geologic plates; contact the MGS Map Sales office at 612-627-4780, ex. 238 and specify publication County Atlas Series C-23, part A, or County geologic atlas of Benton County.

Parts A and B are published and distributed as two separate products.
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. Background GIS data layers such as roads, surface hydrography, township grids, etc., are obtained from various sources, as noted in the Entity/Attribute section.

Section 5 Entity and Attribute Information Top of full metadata Top of page
Entity and Attribute Overview The published paper maps included in the geologic atlas can be viewed as pdf versions of the plates (see directory plate_pdfs):
pl1_db.pdf = data-base map
pl2_bg.pdf = bedrock geology map
pl3_sg.pdf = Quaternary (surficial) geology map
pl4_qstrat = glacial geology cross sections
pl5_bt_dt_sdm = bedrock topography, depth to bedrock, and sand distribution model

Shapefiles to support these plates are described in associated metadata.
