"2013 OSIP Base Digital Orthoimagery Project - The 2013 OSIP digital orthoimagery was collected during the months of March and April (leaf-off conditions).Products produced were 4-band, 8-bit orthophotos with a 0.5-foot ground sample distance (GSD). The aerial imagery was collected during leaf-off conditions at a minimum resolution of 0.5-foot. The orthos are delivered as countywide datasets, consisting of 5,000' x 5,000' uncompressed 8-bit, 4-band color geotiff files. Horizontal accuracy is based upon NMAS Standards for 1"=200' scale base mapping. Along the perimeter of the project area, ortho-imagery is buffered at 1,000-feet (state borders covered by land) and 2,500-feet along the Lake Erie Shoreline. Adjacent flight lines overlap [...]

"The state of Ohio has a goal to develop and maintain a seamless statewide base map, referred to as OSIP (Ohio Statewide Imagery Program). OSIP is an initiative partnered through several State Agencies (i.e. ODOT, ODNR, OEPA) through OGRIP. USGS is also a partner. Data from this project forms the foundation of the statewide base map, and was developed primarily to support multi-use applications, including homeland security, emergency management, economic development, and the business of government." A digital orthoimage is a geometrically accurate photographic record of landscape conditions at the time of the corresponding aerial photography. As such, High Resolution Orthoimagery is useful for a variety of applications, such as environmental monitoring, facility engineering/maintenance, city/county planning, property line review, etc. The digital orthoimage can be used alone or as a raster basemap for corresponding vector line mapping. The detailed focus of High Resolution Orthoimagery provides emergency responders critical information in determining the best evacuation routes, alternative routes and safe access to aid. High Resolution Orthoimagery assists law enforcement personnel in determining the best locations to place surveillance cameras in high-traffic urban areas and popular attractions. The data assists Federal, State and local emergency responders in planning for homeland security efforts. This data also supports The National Map.
