Welcome to the GEOhio Spatial Information Portal

GEOhio is an Open Data Portal that provides access to more than 40 terabytes of geospatial data maintained by the State of Ohio. Datasets are available to the public for download and have no use restrictions. The Ohio Department of Administrative Services Office of Information Technology provides high performance networks and computing infrastructure for GEOhio providing access to discover, view, and download data and services from State and Local government partners.  

The Ohio Spatial Data Infrastructure (OSDI) consists of framework data themes that align with the National Spatial Data Infrastructure (NSDI). As OSDI data sets are developed they are made available for through the OSDI Downloads site and the Map and Data Services site.
