Regional Hydrogeologic Assessment (Part A) - Red River Valley, Minnesota

This page last updated: 04/11/2007
Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Minnesota Department of Natural Resources and 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.

A Regional Hydrogeologic Assessment (RHA) is similar to a County Geologic Atlas in that both geology and ground water are studied. However, a Regional Hydrogeologic Assessment covers a larger area, typically four to nine counties, in less detail. The RHA emphasizes near-surface geologic, ground water, and pollution sensitivity mapping.

The RHA emphasizes near-surface geologic, ground water, and pollution sensitivity mapping.
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.

Entity and Attribute Overview
Entity and Attribute Detailed Citation ARC COVERAGES:

This index lists the significant covers used to generate
the plates for the Red River Valley Regional Hydrogeologic Assessment.
Digital work was acquired and digitized from summer of 1993 - winter 1995.

The covers are divided into two identifying prefix types:
re = Red River Valley Extended, this includes eastern North Dakota
rr = Red River Valley in Minnesota only.

Base layers (except township) modified from USGS DLGs by
Dave Lorenz of USGS; further modified by Kim Esser of MGS.
Township grid & annotation prepared by Kim Esser.
Surficial geology and Quaternary stratigraphy coverages by MGS GIS staff with editing & cleanup by Kim Esser and Joyce Meints.

Red River Valley (rr) Base layers:

rrpgpa = project area boundary and county outlines; polygon coverage
rrpglk = lakes; polygon coverage
rrlnhy = rivers; line coverage
rrlnrd = major highways; line coverage
rrptrd = points for markersymbols with highway ids; point coverage
rrptcity = city location points
rrpgur = urban outlines; polygon coverage
rrpgtr = township-range grid; polygon coverage
rrlntp = topographic contours; line coverage
rrptll = latitude-longitude tics; point coverage


Red River Valley Extended (re) Base layers:

repgco = project area boundary and county outlines; polygon coverage
relnhym = rivers (modified); line coverage
relnrd = major highways; line coverage
reptrd = markersymbols with highway ids; point coverage
reptcity = city location points
repgur = urban area outlines; polygon coverage
repgtr = township-range grid; line coverage
relntp = topographic contours; line coverage
reptll = latitude-longitude tics; point coverage
rean = county names; annotation cover

Quaternary Stratigraphy:

repgqs = quaternary statigraphy; polygon coverage
relnim = ice margins; line coverage
rectxs = cartographic cover of cross section lines


Surficial Geology:

rrpgsg = surficial geology; polygon coverage
rrlnsg = surficial geology; line coverage
rrlnim = ice margins; line coverage
rrctsg = cartographic cross section lines

For listing of MGSCODES for geologic features, see MGS file mgscode.txt, which is included in this dataset. This file is also available from the Minnesota Geological Survey ftp site at:
ftp://156.98.153.1/pub/misc/mgscode.txt

ARCVIEW SHAPEFILES:

Most of these files are also available as ArcView Shapefiles, in UTM Zone 15 Extended, NAD83. This conversion was done by LMIC in summer, 1999. File naming had to be modified somewhat, since each feature type included in a coverage must have its own shapefile. File naming for ArcView shapefiles is as follows:

1. The first 6 characters of the arc cover name are used.

2. When shapefiles are created, polygon shapefiles have the suffix (pg),
line shapefiles have the suffix (ln), and point shapefiles have the suffix (pt).

Annotation covers have not been converted to shapefiles because the text does not convert.

Example: repgqs (quaternary stratigraphy coverage) becomes:
-- repgqspg.shp, .shx, etc. (polygon file)
-- repgqsln.shp, .shx, etc. (line file)
-- repgqspt.shp, .shx, etc. (point file)
-- annotation file not converted.
