SURVEY
Land Survey in the Colony serves two main purposes; first the delineation of town planning layouts, the setting out of public works and the boundaries of private lots and government sites, etc, i.e. cadastral survey; and second the production of plans and
maps.
Cadastral survey continued at a reduced tempo during the early part of the year, although there was a noticeable quickening of demand following the renewal interest in private development which occurred in the latter part of the year.
Plans at the very large scale of 50 feet to one inch (1:600) are now available for the whole of Hong Kong Island, Kowloon and New Kowloon and many of these can be supplied with contours at five, feet vertical interval. Over half of these plans were completely revised during the year and brought up-to-date.
Some seven hundred survey sheets have been ordered to cover the unmapped part of the New Territories at a scale of 100 feet to one inch (1:1,200), and most of these have been supplied. The contract will be completed by the end of next year.

A new drawing technique, in which lines are scribed on a plastic sheet, was introduced this year and the existing 1:2,400 scale series is being re-drawn. It is expected that this technique will be extended to both the 1:600 and 1:200 scale series in 1970.
Field-checking of the 1:10,000 scale map series produced by the Directorate of Overseas Survey in Britain continued during the year and it is expected that the full series of 62 sheets will have been published by early 1970. Special equipment for producing proof copies of coloured maps was purchased during the year to enable revision of the 1:10,000 scale series to be carried out and the first revised sheet will be printed early in 1970. The revision of this series will continue during next year and it is hoped also to produce during 1971 the first sheets of a dual language edition.
