May be <br />exported to a number of formats. <br /> <br />Image Quality <br /> <br />Images will have clear views of the ground and will be fi'ee from obstruction by <br />clouds, however there may be occasional cloud and other shadows. In <br />controlled airspace, around airports, etc., the image resolutions may vary. <br /> <br />Relativelmage Accuracy: <br /> <br />Expected to be within 5 meters over 1000 meters <br /> <br />Absolute Image Accuracy: Expected to be within 2-5 meters (Coordinate location accuracies subject to the <br /> accuracy and posting interval of the County Digital Elevation Models and the <br /> maps used to plan the flight lines.) <br /> Final accuracy numbers are still being computed based on a large number of image samples. Accuracy <br /> values will be calculated according to NIMA's MIL-600001 accuracy specifications. Results from the <br /> testing and calibration will be made available as soon as they are completed. <br /> <br />Page I of 2 <br /> 0201 <br /> <br /> <br />
