Abstract

We describe here work which has been performed to calibrate digital cameras for band-dependent fall-off. We also report studies of the effects of altitude on digital camera data due to change in the size and content of the ground instantaneous field of view (GIFOV), and due to the changing atmospheric path with altitude. We report measurements of calibration targets, and some of trees and crops. We discuss the variation of signal with view geometry and field angle. We show that correction for the band-dependent lens fall-off improves the appearance of images, and the uniformity of derived vegetation indices across images. We report the on the impact of cloud shadow on vegetation index, and on the implications for flying height.
