Service Description: This 1":100' scale imagery is comprised of natural color orthophotography. Photography of the site is acquired using two USGS calibrated/approved aerial camera systems mounted in two twin-engine aircrafts. Film type used was AGFA Color X100. Camera information: 1. Zeiss RMK Top 15, serial no. 145860, focal length of 152.483mm, AWAR 101, last calibrated in Sept. 2003. 2. Zeiss RMK Top 15, serial no. 142832, focal length of 153.850mm, AWAR 101, last calibrated in June 2003. The imagery was obtained on March 7th and 14th, 2006. This image complies with ASPRS Class II standards. It has been tested at 95% confidence level to have an RMS positional displacement within 2 feet of well defined ground features in obscured areas. Does not apply to vertical surface features, such as structures, appearing in the digital orthophotography due to inherent lean. Tested horizonatal RMSE on controls within the project area is 0.97 feet.
