Abstract
These are the third experimental works on the vertical accuracy of aerial photographs as a continued report of Vol.1, No.3 in 1962 and Vol.2, No.3 in 1963. The aerial photographs at a scale of 1: 7920 taken by the RC 8 camera with the Aviogon lens were measured with the Wild A7 Autograph using the correction plate and the Kelsh Plotter independently by each three men. The square mean errors are between ±17cm and ±37cm for the Kelsh Plotter and ±14cm and ±20cm for the Wild A7 Autograph. These result is shown in the graphical form in the following thesis and you can easily understand in comparison with the former experimental result without the correction plate.
