| Abstract | This layer, (BDRKHYDR), describes the bedrock hydrogeologic conditions of 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-2 (Hydrogeologic Map of Minnesota: Bedrock Hydrogeology), 1978, by Roman Kanivetsky. (1:500,000). Map data was orginally grid-cell-coded by LMIC into a statewide 40-acre parcel representation in EPPL; the EPPL file was later converted to Arc/INFO using a state transformation process. |

| Ordering Instructions | This data set is distributed on the internet by clicking below after Online Linkage. Doing so will tell your browser to start downloading a self-extracting 'ZIP' file which will contain the following: - Arc Export file (.e00) of coverage. - Legend file (bdrkhydr.leg) for the dataset - Metadata (bdrkhydr.htm) file for the dataset - NOTICE.RTF, an important notice about this data set that can be read by most word processing software, and an ascii text version of the same notice (NOTICE.TXT) After downloading this self-extracting 'zip' file (which will have an '.exe' extension), simply execute (run) the file. (For example, you can double click it from Windows Explorer or File Manager). Doing this will automatically extract the files described above. You can then delete file types that you do not need, if any. |

| Associated Data Sets | Map: 'Hydrogeologic Map of Minnesota: Bedrock Hydrogeology', Minnesota Geological Survey Map S-2, 1978, by Roman Kanivetsky, is the basis for this data layer. Map is available from the Minnesota Geological Survey Bookstore (612) 627-4782. Other maps and associated data sets at statewide scale include Bedrock Geology, Quaternary Geology, and Quaternary Hydrogeology. In EPPL Grid format this data layer is also part of the LMIC MGC100 data set. File names are BDRKHYDR.EPP and BDRKHYDR.LEG. |

| Section 2 | Data Quality Information | Top of full metadata | Top of page | |
| Attribute Accuracy | Attributes have been verified. Fifteen polygons within the state have a bedrock geology code of 0. Of these, 14 occur in the Red River Valley and are single or double grid cells (Originally 40-acre cells in EPPL), which due to the sinuosity of the Red River, were classified as not-in-state after gridding. These were not reclassified when the file was converted to arc/info. A fifteenth unclassified polygon occurs for the same reasons at the tip of the arrowhead. | |||
| Logical Consistency | ||||
| Completeness | State file is complete. | |||
| Horizontal Positional Accuracy | ||||
| Lineage | Grid Cell Coding: Base map data were encoded using manual map transfer and grid overlay techniques. Coding was done on the 1:500,000 statewide paper map. The dominant hydrogeologic feature was coded for each forty-acre parcel. Conversion to Arc Format (mid-1980's): EPPL Statewide data set was converted into Arc/INFO format using an .svf (single variable file) input. The coverage in Arc/INFO keeps the 'stairstep' nature of the original grid data set. File remained in EPPL coordinates. Conversion to UTM Zone 15 NAD83 (1999): The file was converted from unprojected EPPL grid coordinates to UTM, Zone 15, NAD27, using a statewide map transformation. A TICFILE with 50 points statewide was used to transform the 'flat' 40-acre file into a file with a projection. The file was then converted from NAD27 to NAD83 using the arc 'PROJECT' command. |
