General
SURVEY DIVISION
4.22. The year brought many changes in the Survey Division as the large-scale Air Survey of the Colony got under way. The main Triangulation was recomputed and adjusted, and a false origin was established south-west of the Colony so that all co-ordinates in future would be positive, i.e. East and North.
4.23. Training of surveyors in establishing ground control for air survey and in checking machine plots was initiated, and the responsibility for Land Survey for Architectural Office works was transferred to this office.
Triangulation and traversing
4.24. 170 new triangulation stations were established and 28 miles of precise traversing were run to establish 417 permanent survey marks.
Levelling
4.25. 12 miles of precise levelling were carried out to establish 18 bench marks and 33 miles of ordinary levelling to provide spot heights were completed.
Revision
4.26. 7,562 acres or nearly 12 square miles were surveyed for the large-scale 1/600 survey of Hong Kong and Kowloon, bringing the total number of sheets available in this series to 294 (186 for Hong Kong and 108 for Kowloon). Second revision survey continued in the Tsim Sha Tsui areas and parts of Victoria.
