67. Large Scale Plans: Of the pre-war scale 1/600 and 1/2400 Survey Sheets about fifty per cent were recovered on re-occupation of the Colony but many of those recovered are only sunprints or tracings and are in very poor condition.
In Hong Kong seven new Survey Sheets of Repulse Bay, Tytam Gap and City Districts and one new tracing of Shek-O were taken up, one new Survey Sheet scale 1/2400 of Yau Tong was taken up in New Kowloon and in the New Territories eleven new Survey Sheets scale 1/2400 of Fanling, Tai Lam and Sham Tseng to Tsing Lung Tau were taken up. In addition the Cheung Chau Island Plan scale 1/2400 was gridded with graticule to Colony co-ordinates.
68. Reduction:-This was carried out on the following surveys-At Brick Hill in Hong Kong 8 acres was reduced from scale 1/600 to the scale 1/2400 (Survey Sheet tracing 230 NE); in New Kowloon 2 miles of Clear Water Bay Road, Kai Tak, was reduced from scale 1/2400 to scale 1/20,000 to revise the 1/20,000 topographical map sheets Nos. 15 and 19, and in the New Territories 8 acres of Sham Tseng Brewery scale 1/600 survey sheet was reduced to scale 1/2400 (Survey Sheets 143 SW, 142 SE and 159 NE).
69. No new survey sheets have been wholly completed during the year but a complete set of scale 1/2400 tracings of Victoria, Kowloon and New Kowloon have been produced.
70. Small Scale Maps or Plans:
The Colonial Office List Map of Hong Kong and New Territories, Scale 0.238 miles to one inch was revised by insertion of new roads, reservoirs and other details. A map of the Colony Scale 3 miles to one inch showing height features and a key-map of Hong Kong-Canton-Macao natural scale 1:1,000,000 were prepared for printing with the Annual Administrative Report.
