Abstract
Abstract. Disaster management aims to reduce catastrophic losses of disasters. Geographic information technologies support disaster management activities for effective and collaborative data management considering the complex nature of disasters. This study with an original conceptual approach aims to develop interoperable geographic data model and analysis tools to manage geographic data sets coming from different sources. For landslide disaster, 39 scenario-based activities were analysed with the required data according to user needs in a cycle of activities at mitigation, preparedness, response, and recovery phases. An interoperable geographic data model for disaster management (ADYS), enabling up-to-date exchange of geographic data, was designed, compliant with the standards of ISO/TC211 Geographic Information/Geomatics, Open Geospatial Consortium (OGC), and the Turkish National GIS (TUCBS). An open source and free analysis toolbox was developed and tested in the case study of activities such as landslide hazard analysis and a disaster warning system to support the Provincial Disaster Management Centres of Turkey. Open data models and analysis tools make effective activity management and data sharing possible. However, transforming data sets into data exchange formats is laborious.
Highlights
Disaster is a natural, manmade, or technological event which causes physical, economic and technological losses for the community and suspends the daily life of people with great destruction, ecological problems, loss of human life and deterioration of health (UNISDR, 2009; WHO, 2005; FEMA, 1990)
It is supposed that if data providers produce geographic data sets depending on these data models, data sharing and cooperation will be possible between actors for disaster management activities at mitigation, preparedness, response and recovery phases
Thirty-nine activities at all disaster management phases of landslide can be managed with this approach and it represents a new approach for integrated disaster management in the public institutions
Summary
Manmade, or technological event which causes physical, economic and technological losses for the community and suspends the daily life of people with great destruction, ecological problems, loss of human life and deterioration of health (UNISDR, 2009; WHO, 2005; FEMA, 1990). Landslides, amongst the most damaging disasters in mountainous regions especially, cause loss of lives and affect the economy. In Turkey, the annual economic loss due to landslides is about USD 80 million, the the second most destructive natural disaster after earthquakes. Disaster management works in a cycle of activities at mitigation, preparedness, response and recovery phases. Mitigation phase activities analyse risks and reduce the possible impact of disasters, and the preparedness phase activities plan to ensure a rapid and effective response. Response phase activities include emergency operations for minimizing effects during the disaster event and the recovery phase returns life to normal after the disaster (Orchestra, 2008; OASIS, 2005)
