production is due to three main factors, the additional staff gained from the title sections where work had fallen off, the new simplified specifications for 1/600 and 1/1,200 scales, which are expected to have an even greater impact next year, and the use of new methods of survey made possible by modern equipment such as electro-magnetic distance measurers and radio-telephones.
7.26 Three additional electro-magnetic distance measurers have recently been delivered and a fourth with a much longer range is on order and is expected to arrive next year. These instruments greatly simplify the provision of control points required for revision and should further improve the production rate in 1973-74.
Title Survey
7.27 The demand for boundary surveys declined during the year under review but again showed a sharp increase during the last quarter and the arrears at the end of this period were approaching a record high level, exceeded only during the third quarter of 1971-72. Should this trend continue the Survey Branch will again find itself under severe pressure and longer delays in carrying out title surveys may result.
7.28 Work has continued on calculating the intersection points where the Mass Transit reserves cut the boundaries of lots about to be developed or re-developed, in order to protect the proposed rail route during piling operations, etc. This data is then available to the owner/developer as part of the relevant dimensioned or setting-out plan.
Local Air Survey
7.29 Photography for plotting purposes, using the RC10 air survey camera, commenced in April and continued at a steady pace during the year. Plotting of many sites, for the Engineering and Architectural Offices, has been carried out under contract in the United Kingdom. Vertical photography was provided following the rainstorm damage of June, and was used for planning remedial works in the disaster areas and as a record for the Commission of Enquiry. This work and oblique photography from a helicopter placed a very heavy workload on the photographic and reprographic staff of this office.
