still outstanding in this field. At the end of the year there were 290 Lease Surveys, 30 surrenders and 114 other title surveys still outstanding. Statistical details are given at Appendix T.
Survey Computations
5.15. Computation occupies a considerable proportion of a surveyor's time and much thought has been given to methods and mechanization of this work to increase output and make sure all work is adequately checked. The office has adopted the Facit C1-13 hand-operated calculator as the standard and is working on a basis of one calculating machine for every three Surveying Assistants.
5.16. During the year the office acquired an Anita table-top electronic computer complete with female operator and they have been employed on checking work. It has been found that one operator can check the work of approximately thirty assistants and it is proposed to extend this system.
Air Survey
5.17. A considerable proportion of the Survey division's work for the year was in connexion with the $6 million Air Survey contract commenced in 1963. The Survey division provides all ground control required by the contractors and carries out the field checking of machine plots both detail and contours. It also provides name sheets to incorporate in the final prints.
The contractors supplied the following fair drawn sheets:
48 Nos. Scale 1/600 (50′=1′′) Urban Areas, viz. Hong Kong Island and Kowloon. 215 Nos. Scale 1/1200 (100′=1′′) Rural Areas, New Territories. 11 Nos. Scale 1/2400 (200′=1′′)5.18. The Director of Overseas Survey agreed to plot the smaller scale series, i.e. 1/10,000 and 1/25,000 maps so that Hong Kong will no longer have to rely on the Military Survey for maps. The necessary ground control for these series is now being surveyed by the Colony surveyors.
