LineageThe following two polygon coverages were combined with the ARC command, 'union.'
  • The Minnesota Geological Survey's (MGS) bedrock geology polygon coverage (from The Stearns County Geologic Atlas, Part A, Plate 2) 
  • The MGS' depth to bedrock polygon coverage (from The Stearns County Geologic Atlas, Part A, Plate 6)
All polygons with a depth to bedrock value less than 50 feet were selected and placed into a separate coverage.

The item 'aqclass' was added to the polygon attribute table of the resulting coverage, and given the value of 'K' for all polygons with a 'unit_code' designation beginning with 'K.' 'unit_code' is one of the attributes in the MGS' bedrock geology coverage, and all unit_code values that begin with 'K' refer to Cretaceous units. All other polygons (except for "island" polygons - see Entity and Attribute Information, below) were designated 'P,' - Precambrian. 

The coverage was dissolved on the item 'aqclass' to create 'br50.'

 AQCLASS 1,1,c Type of bedrock
    'K'Cretaceous
    'P'Precambrian
    'O'"Island" polygons - polygons of depth to bedrock greater than 50 feet that are completely surrounded by polygons of depth to bedrock less than 50 feet.

 EDGE 1,1,c Demarcates lines coincident with county border.
    'y' or 'n''y' - indicates lines coincident with the county border. All other lines are designated 'n.'
 

Allows for de-emphasizing county-coincident lines so that they do not interfere with the county border when it is displayed.
