Mower County Geologic Atlas - Part A

This page last updated: 04/06/2007
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.

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
Logical Consistency
Completeness
Horizontal Positional Accuracy
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.

This index lists the significant covers and associated files constructed for the Mower County Geological atlas, 1996-1998.

Base layers (except township) modified from TIGER census data. Township grid & annotation, line symbols, fonts, markers, and map layout and plot generation aml prepared by Joyce Meints. Bedrock related geology linework by John Mossler, Surficial geology related linework by Gary Meyer, ARCINFO cover creation, with digital editing done predominantly by Emily Bower, Joyce Meints, Phil Heywood & final editing and cleanup by Joyce Meints.

The majority of geologic linework was scanned off mylar stable base, made into a TIFF image, the image was registered and converted into a GRID which was then vectorized via VTrace in the Arcedit environment.
