145. 3 miles of ordinary levels were run to provide spot heights on the 1/600 survey sheets of Victoria.
Revision
146. 1,678 acres or 2.6 square miles were surveyed for the large scale 1/600 survey of Hong Kong and Kowloon, involving 117 miles of detail traverse. 84 sheets of this series (52 of Hong Kong and 32 of Kowloon) are now available.
Topographical
147. Contour surveys for town planning and development schemes covered 2,357 acres or 3.7 square miles. The surveys have been plotted at:
Scale 1/600 Scale 1/1200 Scale 1/2400 206 acres 10' V.I. 1,214 acres 10' V.I. 937 acres 20' V.I.Miscellaneous
148. Surveyors attended court on twenty-one occasions to give evidence. These cases involved 20 surveys, covering 73 acres.
149. 7 miles of road line were set out for development and rebuilding schemes, and 4 miles of building line were checked for the redevelopment of 104 lots.
Drawing
150. Two plans at scale 1/9600, covering the Harbour and Tsuen Wan areas, were completed; these were prepared from reductions of the large scale surveys. Work started on the compilation and drawing for tourist purposes of a 'popular' edition 1/100,000 map of the Colony, with a modified edition of the harbour sheet printed on the back.
