The paper describes an experiment using three different methods for the production of control for topographic mapping from super‐wide angle photography. The result showed that aerial triangulation by independent models observed on a Wild A9 would show economic advantages in cartographic effort required, control requirements, and accuracy attained in contouring. The experiment also indicated that great benefit in heighting accuracy is derived from the addition of tie strips flown at right angles to the main photographic cover at a suitable interval and that heights supplied by airborne profile recorder are not sufficiently accurate to be economically advantageous where close interval contours are a requirement.
