Abstract : The 1:20,000 - 1:35,000 scale aerial photography commonly used in compiling 1:25,000 scale topographic maps does not always permit certain interpretation of ground features or correct identification of control points. Experiments in 1965 with supplementary aerial photography at scales of 1:5,000 and 1:8,000 enabled office interpretation reliability about equal to that obtained by field check methods. Tests were carried out with this camera mounted in a pod attached to the landing gear support struts of a helicopter. Such photography permits identification and precise transfer of ground control points to the main survey photographs by means of an interpretscope; permits selective photographic coverage of cultural features constructed subsequent to the main survey photography; and permits timely photographic coverage of shorelines at highest tide and rivers at mean water level.
