LARGE SCALE AERIAL MAPPING SURVEY OF HONG KONG
To Assist In Planning Future Satellite Towns, Major Engineering Projects
+
Areas in the New Territories earmarked for development under the
10-year housing programme are being mapped from the air on the largest
scalo over attempted by the Survey Branch of the Crown Lands and Survey
Office.
During the past few months, some 3,000 aerial photographs of the
New Territories and outlying islands have been taken through a special
camera installed on board the twin-engined "Islander" aircraft of the
Royal Hong Kong Auxiliary Air Force.
From the air photographs, plans at 1:500 scale with contours at
one motre intervals will be plotted by photogrammentry, the science of
plotting maps accurately from air photographs. The new 1:500 plans arc
among the first to be produced for Hong Kong at metric scales and with
metric contours and spot-heights, and will be of immense benefit to the
planning of future satellite towns and major engineering and architectural
projects, a spokesman for the Survey Branch said.
In addition to this special mapping for the engineers and architects
who are planning and designing the new towns, 'strip-maps' for now roads
and for the improvement of existing roads are being produced. Those include
the now Castle Peak Road, the South Lantau Road and a new road to Clear
Water Boy Beach.
Apart from these very large-scale engineering plans, other maps
at 1:1,000 scale, with contours at two metres intervals, will be produced
for the Crown Lands and Survey Office to replace the existing series at inch/foot
scales.
