Description: This data layer contains the mine-point locations found on the 1:24,000-scale bedrock-geology maps of Ohio. The mine points were drawn on the maps to show where surface mining has affected the depiction of the bedrock geology. Detailed mapping at 1:24,000 scale was performed in Ohio from the 1960's to the 1980's. During that time period, 37 7.5-minute quadrangles were mapped in detail. The bedrock-geology mapping program was initiated at the Ohio Division of Geological Survey in 1991 to perform reconnaissance geologic mapping at 1:24,000 scale. The reconnaissance and detailed geologic mapping have been combined together into this GIS dataset. There will be edge-matching issues between the reconnaissance and detailed geologic maps.

Description: The Surf_Mines dataset contains a subset of features extracted from two datasets maintained by the Ohio Department of Natural Resources (ODNR) Division of Mineral Resources Management (DMRM). The first polygon layer known as SurfMines_AMLIS was developed in 2006. The source of data for SurfMines_AMLIS was AMLIS Quad maps that were edited in 1980/81 as part of the initial AMLIS inventory. The paper quadrangles (quads) were utilized in aerial/terrestrial reconnaissance. Areas were demarcated as being affected by surface mining and the status of reclamation was noted. In 2006 the AMLIS Quads were scanned and digitized by the Ohio Penal Industries (OPI) producing the SurfMines_AMLIS polygon layer. The second polygon layer known as SurfMines_DRG was developed in 2008/2009. The source of data for SurfMines_DRG was current digital United States Geological Server (USGS) Quadrangles otherwise known as Digital Raster Graphic(s) (DRGs) downloaded from the Ohio Geographically Referenced Information Program (OGRIP) in 2008. Areas demarcated as being affected by surface mining were digitized by the Institute for Local Government Administration and Rural Development (ILGARD) at Ohio University producing the SurfMines_DRG polygon layer. Care was taken to reduce duplication of data contained in the new dataset. The first step was to isolate areas from each surface mine dataset that could have abandoned mine land problems and also be funded according to the Surface Mining Control and Reclamation Act (SMCRA). Since no one data source fits our needs the spatial boundaries of known C & D coal permits were used to remove polygons from the AMLIS and DRG datasets. The next step utilized the DMRM produced AMLIS dataset as a base, once the C & D permits were removed the AMLIS dataset was overlapped with the DRG dataset and a reverse selection was made from the DRG dataset. The end result was a layer that included all polygons from the AMLIS dataset that did not overlap with C & D permits and also all polygons from the DRG dataset that did not overlap with C & D permits or overlap with the AMLIS dataset.
