The largest scale plans previcusly produced by the Survey Branch
have been at 50-feet: 1 inch (1:600) for the urban areas of Hong Kong
and Kowloon, and 100 feet: 1 inch (1:1,200) for the whole of the New
Territorios.
The survey data and the aerial photographs on which the surveyed
control points have been pinpricked are being sent to two specialist air
survey firms which were recently awarded contracts for the photogrammetric
plotting of details from the photographs onto the plans. The firms are
Associated Surveys Pty. Ltd. of Perth, Australia, and B.K.S. Surveys Ltd.
of Northern Ireland.
A spokesman for the Survey Branch explained that two contracts
were awarded partly becaus of the increasing amount of wapping urgently
required and partly because the two firms had come up with very close bids.
"A major advantage of this arrangement," he said, "is that the
period of time needed to complete the required mapping will be considerably
shortened. This is vitally important in view of the great urgency of the
10-year housing programme."

Tho spokesman said specialist firms were needed to carry out the
photogrammetric plotting because this sort of work required expensive
equipment and highly trained operators.
Ho also pointed out that there would be a concentrated and urgent
demand for this sort of work in the next year or two in connection with the
housing programme.
"It will be followed by a continuing but less urgent
demand indefinitely when all existing plans will be revised and re-contoured in
metres.1
