Surveying If v, t and f/H are the ground speed of the aircraft, the shutter speed of the camera and the scale of the photograph respectively, then the amount of image displacement i = v. t. H/f i = v. t. (f/H) i = v. f/t. H i = t. H/v. f i = v. t. H/f i = v. t. (f/H) i = v. f/t. H i = t. H/v. f ANSWER DOWNLOAD EXAMIANS APP
