Abstract

Long Range Oblique Photography (LOROP) has been investigated briefly as a means of collecting quantitative data about very distant scenes. Two measuring aspects are discussed: first, producing dimensional data about the sizes and heights of man-made objects, and, secondly, measuring the geographic location of an object. This latter task is rather new for the photo intelligence specialist, who in the past generally did not have available these photogrammetric capabilities. We show in this contribution that at stand-off distances of 130 kms (80 miles), a position can be routinely measured with an accuracy better than ±10 m, in less than 15 minutes.
