| Title | Geologic Map of Minnesota - Quaternary Geology, (MGS Map S-1), 1982 | |||
| 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. In 2008 MGS converted the original linework to a shapefile format and added more descriptive fields based on the Quaternary Geology Code. File geodatabase format was created for the Minnesota Geospatial Commons. | |||
| 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: Quaternary Geology', Minnesota Geological Survey Map S-1, 1982, J.C. Hobbs and J.E. Goebel, is the basis for this data set.
The Minnesota Geospatial Information Office (MnGeo) (formerly the Land Management Information Center - LMIC) created the original 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 Quaternary Geology Code information from the map was manually added to the data set and check. The Arc/INFO polygon coverage was later converted from single precision, NAD27, shifted, to double precision, NAD83 unshifted, using the Arc 'PROJECT' command. (Filename: mnsg83.e00). The Minnesota Geological Survey converted the coverage to a shapefile and in 2008 added further descriptive fields based on the QGEOCODE. (Filename: s1pgcolor). Both files were imported into file geodatabase format in 2015 for inclusion in the Mn Geospatial Commons. 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. | |||

| Overview | s1pgcolor is the quaternary geology polygon file created by MGS in 2008 with additional attribution added to the coding in the mngs83 polygon file.
mngs83 (poly, arc, tic, and label) is the original Arc/Info coverage file created by LMIC in 1985. Coding is the original attribute coding from the map. QGEOCODE values should be the same for both files, but the s1pgcolor has the newer, more complete attribute coding and is the file recommended for use. Coding for the s1pgcolor file is described under Table Detail. | |||
