The 2006 OSIP digital orthophotography was collected during the months of March and April (leaf-off conditions). The MrSID
Images covering each county at 1-foot pixel resolution will be created at a 30:1 compression ratio. At a 30:1 compression
ratio, the resulting MrSID file size will average around 2GBs in size (dependent upon county size). MrSID Images will also
be created for each buy-up county. These MrSIDs, will be compressed at a 20:1 ratio. In some cases, buy-up counties have requested
a higher compression ratio. Hancock and Fairfield Counties have requested countywide ECW image files.

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) through OGRIP. 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.Orthoimagery data are used during DFIRM
production, which have been kept separate from the other framework themes for future consistency with the NDOP registry.

source description
Source Contribution: The aerial imagery acquisition for the State of Ohio was flown to support the creation of digital orthophotography
with a 0.5-foot and 1-foot pixel resolution. The 0.5-foot pixel ortho imagery was flown at an approximate altitude of 4,800-feet
AMT. The 1-foot pixel ortho imagery was flown at approximately 9,600-feet AMT. Imagery was flown with an average 30% overlap
between flight lines All imagery was collected using the Leica ADS40/51/52 digital camera system.Source Type External Hard

name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
The 1"=200' scale orthophotos were created to meet 5.0-foot horizontal accuracy, meeting NMAS.The 1"=100' scale orthophotos
were created to meet 2.5-foot horizontal accuracy, meeting NMAS.

Completeness Commission
evaluation Method Description
Complete and integrated data for an entire county are preferred. If only portions of a county are available, FEMA may choose
to use the default base map source (USGS DOQs) for the county. (Guidelines and Specifications Vol 1, p 71).

ConceptualConsistency
measure Description
Compliance with the accuracy standard was validated by the collection of photo identifiable GPS ground control points during
the acquisition of aerial imagery. The following checks were performed.Digital orthophotography was validated through an inspection
of edge matching and visual inspection for image quality.
