The provision and maintenance of the precise survey system in both the horizontal and vertical senses. Horizontal surveys by means of triangulation nets and/or traverse lines provide an integrated survey system upon which all surveys in the Colony are based. Vertical surveys by means of precise level circuits are necessary to establish, throughout the Colony, fundamental Bench Marks which are strictly consistent with Colony Principal Datum. The emergence of sophisticated aerial survey plotting machines is of no use unless such machines are geared to precise horizontal and vertical control, which must originate from a Land Surveyor's observations on the ground.
Mapping Survey
The delineation, in map form at various scales, of the ground surface topography and cultural detail of the Colony.
The Survey Branch acknowledges that the average map-user tends to judge a mapping agency simply by his own ability to relate any publication to the area in question without considering the degree of sophistication used in its production. Specialised maps, such as the tourist and footpath editions, are therefore produced for those who require maps more easily read than the standard topographical maps.
Title Survey
The cadastral survey and subsequent documentation required by the Land Office in the alienation or surrender of Crown land. The last decade has witnessed the enormous increase in Colony land values which has resulted in land-owners becoming increasingly "boundary-conscious" and this, in itself, emphasizes the need for accurate boundary descriptions. Hong Kong is exceptional in not having a private practice of land surveyors to carry out this work. In many countries the law requires that Title Surveys be carried out by registered surveyors who would normally be professionally qualified. In Hong Kong this work is done entirely by departmentally trained Government technicians under the supervision of professional land surveyors, thus providing a service to the public at a comparatively low cost.
Cartography
The fair drawing, printing and production of maps and plans at various scales.
Survey Training
The P.W.D. Survey Training School was established in 1963 and, since that year, has been continuously heavily engaged in maintaining scheduled Basic Survey and Cartographic Courses. The Basic Survey Course, nine months of intensive study and practice, incorporates all the advances made within the science of survey, particularly that over the last decade, and by the end of the Course the trainee can reasonably safeguard departmental standards.
