These are the second experimental works on the vertical accuracy of aerial photographs as a continued report of Vol.1, No.3 in 1962. The aerial photographs at a scale of 1 : 7920 taken by the RC 8 camera with the Aviogon lens were measured with the stereoplotting machin A 8 (No. 1207) independently by four men.
As for as these experiments are concerned, we recognized to be fully effective for the ordinary engineering purpose.
