Building Survey in the Sydney Central Business District (CBD)

Knowledge of the nature of buildings within CBD areas is fundamental to a broad range of decision makingprocesses, including planning, emergency management and the mitigation of the impact of natural hazards.To support these activities, Geoscience Australia has developed a building information system called theNational Exposure Information System (NEXIS) which provides information on buildings across Australia.Most of the building level information in NEXIS is statistically derived, but efforts are being made to includemore detailed information on the nature of individual buildings, particularly in CBD areas. This is being achievedin Sydney through field survey work.
