Use of aerial photographs for the engineering purposes has been increasing remarkably. But we have never had the thesis concerned to the analysis of the vertical accuracy of aerial photographs in our country. I had the experimental works about comparison of datas obtained from direct levelling with the photogrammetrical method. The aerial photographs at a scale of 1: 7920 taken by the RC 8 camera with the Aviogon were used and measured with A 7 Autograph independently by four men. As far as these experiments are concerned, we recognized to be fully effective for the ordinary engineering purpose.
