5.29. The principal feature of the past year's progress has been the increasing importance of the air survey commenced in 1963. The flow of completed large-scale contoured plans from the contractors, Messrs. Hunting Surveys Ltd., is steadily increasing.
5.30. In addition to the current mapping programme at 1/600 scale (in the urban areas) and 1/1,200 scale (in the New Territories) the air-photographs have been used to produce photogrammetrically large-scale site plans for the Architectural and Engineering sub-departments in preparation for large site-formation contracts at Tsuen Wan, Kwai Chung, Castle Peak and Tsing Yi Island at a great saving in time and cost as compared to the traditional ground survey methods.
Revision of 1/25,000 Series of Maps
5.31. In December the Colony was re-photographed from the air by Messrs. Hunting Surveys Ltd. The new photography was primarily at high level with a view to revising the existing 1/25,000 series of military maps, which are badly out of date.
