Aerotriangulation Precision Attainable for Highway Photogrammetry
Publication: Journal of the Surveying and Mapping Division
Volume 100, Issue 1
Abstract
The magnitude of the standard error, 0.00012 times flight height for large-scale photography was empirically determined by analyzing data from 137 stereo models in 22 flights at heights of 1,500 ft, 3,000 ft, 6,000 ft, and 12,000 ft, taken by Wild RC-8, f=6 in. camera and bridged in a Wild A-7 Autograph. The analysis shows that attainable accuracy changes in a linear form between these heights and this empirical equation may also meet the accuracy of analytical aerotriangulation for large-scale photographs.
