CLOUD PHOTOGRAMMETRY WITH GROUND-LOCATED K-17 AERIAL CAMERAS

Abstract

A technique is presented in which a pair of ground-located K-17 aerial cameras is used on a 1.30-milebaseline to determine cloud ranges to 1-mi accuracy at 40 mi, and cloud-height measurements to within 500 feet at this range. Details of the power supply, vacuum supply, and camera-synchronization requirements are discussed, as well as methods used in analysis. In particular, a detailed discussion is given of the theoretical and practical errors encountered in such a photogrammetric technique.
