PHOTOGRAPHIC ANALYSIS OF WATER QUALITY CHANGES

Black-and-white aerial photography for 1956 and true-color aerial transparencies for 1975 at 1:10,000 scale are used to study the impact of a changing environment on the water quality of Rambler Channel in Hong Kong. The extensive reclamation in the area undertaken by the Government has significantly transformed the land use of the coastal areas and inevitably has led to man-made pollution of the sea water. The aerial photography has been found to be an efficient tool in detecting sources of pollution and in identifying the types of polluting substances, especially with the aid of the true-color transparencies. All these are shown on two maps prepared directly from the aerial photographs with the aid of a Zoom Transfer Scope.
