| Lineage | SOURCE: 1990 Washington County Geological Atlas. PROCESSING STEPS: -Data for the Atlas were collected during 1990 field surveys in Washington County. The Atlas maps were first produced on a paper medium. -The Prairie du Chien-Jordan Pollution Sensitivity (defining areas where units stratigraphically lower than Jordan are first bedrock) map symbol information/linework was extracted from a mylar sheet using a scanner; -Next, attribute codes were added and a line coverage was created. Notes: The Minnesota Geological Society used PC ARC/INFO for digitizing and building the coverage. Washington County has since converted the coverage to an ArcView shapefile, and; converted the Prairie du Chien-Jordan Pollution Sensitivity symbol line coverage coordinates from UTM, GRS80, Zone 15, with a y-shift equal to 4700000, to the Washington County coordinate system The county has also retained a copy of the dataset in its original UTM coordinates. |

| Entity and Attribute Overview | Coverage and Attribute Information for the Prairie du Chien Aquifer Sensitivity to Pollution Map Symbols Dataset: COVER NAME DESCRIPTION (COVERAGE TYPE) PSLNANNO...........Prairie du Chien-Jordan Pollution Sensitivity Map Symbols, defining areas where units stratigraphically lower than Jordan are first bedrock (line) Field Definitions and Attribute Codes for line cover PSLNANNO. ITEM NAME TYPE WIDTH DECIMAL type c 2 gcm_code c 3 geoc_src c 5 geoc_date n 8 mgscode n 6 type: polygon type code. Codes used in covers are as follows: CODE Description PS.....................Pollution Susceptibility gcm_code: geographic coordinate method code. Geographic coordinates for the point were determined, hence implies the accuracy of the lines. Note that the accuracy of coordinates determined by measuring the location of lines drawn on a map (either by digitizing or manual methids) area affected mainly by the skill of the person drawing the line on the map rather than the limitations of the map itself or the digitizing equipment and process. Since it is difficult to assign an error to that part of the coordinate determination process, the accuracy estimates indicated below for digitizing reflect the combined error of the map (assuming National Map Accuracy Standards) and a digitizing table with a + 0.005 inch accuracy rating. The geographic method codes used in covers are: TYPE DESCRIPTION B.............digitized- scale 1:100000 to 1:24000- accuracy 25 to 90 meters (+/- 83 to 296 feet) D.............digitized- scale unknown (refers to US Census Tiger File county borders) geog_src: Geographic coordinate source code. Indicates who (which organization or project) determined the geographic coordinates. geoc_date: the date the coordinates for the lines were determined. Format yyyymmdd. CODE DESCRIPTION MGS.............Minnesota Geological Survey mgscode: internal code used at Minnesota Geological Survey. |
