Abstract

During the war and in the immediate post-war period the Royal Air Force and the United States Army Air Force undertook a considerable air survey programme covering Burma, Siam and French Indo-China. In Siam the initial cover was restricted to large-scale (1:15,000 and better) photographs of towns, airfields and communications. Later a more ambitious programme of survey cover (scales 1 : 50,000 and 1 : 25,000 with a few towns and beaches at larger scale) was undertaken, and practically the whole of the country has been covered by air photographs of one scale or another.
