The ultimate app for Geography/Geology amateurs and professionals."
- Mel Martin, TUAW.com

Do you know which state assembly district you are in? Which school district? Where is the closest railroad? Is there a mine nearby? What kind of rock are you sitting on? Using the iPhones GPS, this app will answer these questions and many more.

Geograph OH is the edition of the popular GIS (geographic information system) covering the state of Ohio. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the geography and geology of the Buckeye State. You can combine various data layers, zoom in and out, and get a lot of details about the physical and human geography of Ohio.
