Summary
Description
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.
