(b) Mapping Survey. Surveys for the preparation of plans and maps of the whole Colony at different scales and their subsequent revision at regular intervals.
(c) Title Survey. The delineation and recording of all property boundaries in the urban areas (and in planned areas of the New Territories); the implementation of all town planning layouts; surveys for surrenders, grants, sales, exchanges, Crown Leases, etc.
(d) Cartography. The production of plans and maps at different scales for both 'mapping' and 'title' purposes.
Control Survey
6.18. For the first few months of the year the main effort continued to be in the provision of ground-control points for the large-scale mapping by air survey of the New Territories. This task was completed in July 1968 and the field staff which had been employed on this work for the last 5 years was distributed to other sections. This enabled more control surveys of other types and precise levelling to be undertaken for the rest of the year.
Mapping
6.19. The proportion of the survey staff employed on checking the machine-plots for the large-scale air survey as they are received from the contractors was reduced during the year as the plotting of Lau Tau was completed. Machine-plots for the Junk Bay, Hebe Haven, High Island and North-East areas of the mainland were checked. The last machine-plots at 1/1,200 scale were received in February 1969 and the work of checking these should be completed by July 1969.
6.20. An expanding programme of revision of large-scale plans is now well in hand. The number of survey staff employed on this work was increased as the task of machine-plot checking was completed.
6.21. In addition to a continuing demand for the setting-out of roads, Government buildings etc., the number of large-scale site surveys, mainly for Architectural Office, continued to rise, a total of 134 sites being surveyed. Requests from the Police for surveys and plans for court cases also rose, a total of 58 being completed during the year.
6.22. The number of Architectural Office sites on which this Office was carrying out regular interim check surveys for the measurement of earthwork quantities was reduced during the year from seven to four.
