Q4/ Points A and B are at elevation 400 m and 200m above datum respectively. photographic coordinates of their images on a vertical photograph are xa= -70mm, ya= -45 mm, xb= -90 mm and yb=30 mm. what is the length of line AB on the ground? If the photo was taken from 3500m above datum, with 150 mm focal length camera.
