{ "culture": "en-US", "name": "", "guid": "", "catalogPath": "", "snippet": "", "description": "This data layer contains the 1:24,000-scale bedrock-geology polygons for Ohio. The polygons were originally derived from the 1:24,000-scale bedrock-geology maps, which were created between the mid 1960's through 1997. 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.", "summary": "", "title": "Bedrock Geology 24K - Units Ply", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 0, "maxScale": 0, "spatialReference": "", "accessInformation": "Ohio Department of Natural Resources-Division of Geological Survey", "licenseInfo": "" }
