Download .zipA soil mapping unit designates a specific type of soil which has unique characteristics including texture, slope, and erosion class.

This coverage was converted to digital format from a recompilation of the original soil survey onto a USGS quadrangle base enlarged to a scale of 1:15840 from the digital line graph files of the quadrangles. The original soil survey was published in February of 1980. Recompilation was accomplished by soil scientists from the Ohio Department of Natural Resources, Division of Soil and Water Conservation. The individual quadrangle maps were scanned by a commercial data conversion firm at a density of 500 dots per inch and then converted to ARC Grid format. The GRID files for each quadrangle were then converted to ARC/INFO coverages and edited through various software routines and manual heads-up digitizing. Quadrangle coverages were converted to state plane coordinates, edgematched and then joined into a final county coverage. Because the quadrangle base is in NAD27 all work was done in NAD 27.

Original coverage data was converted from the .e00 file to a more standard ESRI shapefile(s) in November 2014.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesReal Estate & Land ManagementReal Estate and Lands Management2045 Morse Rd, Bldg I-2Columbus, OH, 43229Telephone: 614-265-6462Email: gis.support@dnr.ohio.gov
