As part of its mission to understand Ohio’s geology, the Ohio Geological Survey has a long history of mapping Ohio’s natural resources. From statewide in scope to local and regional analyses, this division has maps that deal with every aspect the state’s geology. These maps have evolved over time to be more detailed and informative about bedrock, glacial sediments, geologic hazards, oil and gas, coal and industrial minerals, and other topics. Today, the division presents this information digitally as well through interactive, online GIS-based mapping applications.
