GIS application in disaster management: some examples


Remote sensing and GIS have been utilised for disaster management throughout the world. Wellington Regional Council (WRC) has pursued a program of earthquake hazard mapping within the Wellington region, New Zealand. Since 1990, when maps showing active faults were produced, the council has developed a comprehensive library of earthquake hazard maps. Projects have been carried out to map potential tsunami inundation areas around Wellington Harbour, variations in ground response to strong shaking, liquefaction potential, and earthquake induced slope failure. All these data have been digitised and forms part of the WRC GIS. Cyclone threat maps are prepared by the Tropical Cyclone Warning Centre in Brisbane . Black and white copies of the maps are faxed to media outlets, police and emergency services, and can be accessed by anyone who has a polling fax, GIS/GPS were utilised to monitor the daily spread of the fire, measure fire suppression actions, and assess damage to structures and to natural and cultural sources, when a major wildfire occurred at point Rayes National Seashore, California .
