Title Geologic Map of Minnesota: Quaternary Geology, from MGS (Map S-1), 1982 (Digital Version)
Abstract This layer describes the general distribution of surficial sediments in Minnesota, as delineated and classified by the Minnesota Geological Survey. It is a digital version of the Minnesota Geological Survey State Map Series Map S-1 (Geologic Map of Minnesota: Quaternary Geology), 1982, by H.C. Hobbs and J.E. Goebel. (1:500,000). The digital file was created by scanning the 1:500,000-scale paper map and then converting the scanned image into an Arc/INFO polygon coverage. Vector GIS format were later updated to shapefile and file geodatabase.
Purpose To produce a general descriptive layer of quaternary (surficial) geology for the state.
Time Period of Content Date 1982
Currentness Reference Map was delineated in 1982 based on the information available at the time.

Lineage The map: 'Geologic Map of Minnesota: Surficial Geology', Minnesota Geological Survey Map S-1, 1982, J.C. Hobbs and J.E. Goebel, is the basis for this data layer.

The Minnesota Geospatial Information Office (MnGeo) (formerly the Land Management Information Center - LMIC) created the GIS data products. The original GIS file was created by scanning the 1:500,000-scale paper map and converting the scanned image to an Arc/INFO polygon coverage. The Arc/INFO polygon coverage was later converted from single precision, NAD27, shifted, to double precision, NAD83 unshifted, using the Arc 'PROJECT' command.

The Arc/INFO coverage was converted to ArcGIS shapefile format 5/24/2010, and to ESRI file geodatabase format in 2015.

Lineage of grid version: Arc Scanned version (NAD27) was converted into a state 40-acre EPPL file; the file then georeferenced, projected to NAD83, and converted to MGC100 format. This format is no longer being distributed.
