Cadastral surveying is the practice of acquiring and presenting the cadastral information of a land parcel. Such information usually includes the location and geometric descriptions linked to the records of the nature, ownership and affiliated interests of the land parcel. Apart from being the core for land administration and protection of land rights, a comprehensive cadastral record system also plays a fundamental role in land use planning, land development, environmental management and sustainable development. A land surveyor's professional knowledge is unique and essential to the practice of cadastral surveying, in particular, for interpretation of land boundary records, determination of land boundary and managing cadastral information. A professional land surveyor will carry out land boundary surveys in compliance with the Code of Practice under the Land Survey Ordinance (Cap. 473). To register as an Authorized Land Surveyor under the Ordinance, one of the major criteria is being a corporate member of the HKIS Land Surveying Division.
