This data set was created as part of the Black Hills Hydrology Study (BHHS). The BHHS is a long-term investigation that was initiated in 1990 as a cooperative effort between the U.S. Geological Survey (USGS), the South Dakota Department of Environment and Natural Resources (DENR), and the West Dakota Water Development District. West Dakota represents various local and county cooperators. The purpose of the study is to assess the quantity, quality, and distribution of surface and ground water in the Black Hills area of western South Dakota (Driscoll, 1992). The study area includes parts of Butte, Custer, Fall River, Lawrence, Meade, and Pennington counties in South Dakota. Reviews_Applied_to_Data: This electronic report was subjected to the same review standard that applies to all U.S. Geological Survey reports. Reviewers were asked to check the topological consistency, tolerances, attribute frequencies and statistics, projection, and geographic extent. The reviewers checked the metadata for completeness and accuracy. Related_Spatial_and Tabular_Data_Sets: Depth to the top of the Inyan Kara Group (inkr_dep), Minnekahta Limestone (mnkt_dep), Madison Limestone (mdsn_dep), and the Deadwood Formation (ddwd_dep).

The following terminology used to describe the creation of the data set is from ARC/INFO. A polygon coverage of the study area boundary was converted to a grid coverage using the POLYGRID command. Line coverages of the land surface topography and structural surface elevation were converted to grids using command TOPOGRID with a cellsize of 50 meters, and with the border defined by the grid of the study area. Arc: TOPOGRID base_grd 50 TOPOGRID: border bordergrd TOPOGRID: datatype contour TOPOGRID: contour basetopo elev TOPOGRID: end Using GRID, the structural surface elevation grid was subtracted from the land surface topography grid. The output grid was then reclassed into 14 general categories of depth created in the calculation using a REMAP file to assign a range of values to a single integer value for an item named GRID-CODE. GRID: setmask mnlsabfing GRID: setcell 50 GRID: setwindow bordergrd GRID: mnlsdep_grd = basegrd - mnlssurf_grd GRID: mnls_recg = reclass(mnlsdep_grd, shades.lut, nodata) Finally, the grid was converted to a polygon coverage using the GRIDPOLY command in GRID and the CLEAN command in ARC. 20000215 First draft of metadata created by jgallowa using FGDCMETA.AML ver. 1.33 07/15/99 on ARC/INFO data set /home/bhhs/gis/jmg/aquiprop/metadepth/mnls_dep 20001103 Vector Point 315 String 603 GT-polygon composed of chains 316 Point 4 Transverse Mercator 0.999600 -105.000000 500000.000000 0.000000 coordinate pair 1.0 1.0 Meters North American Datum of 1927 Clarke 1866 6378206.4 294.98 mnls_dep.pat Depth to top of the Minnelusa Formation FID Internal Feature number ESRI Sequential unique whole numbers that are automatically generated.
