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 upto-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

Abstract. Disaster Management aims to reduce catastrophic losses of disasters as landslide. Geographic information technologies support disaster management activities for effective and collaborative data management considering complex nature of disasters. Thus, this study aims to develop interoperable geographic data model and analysis tools to manage geographic data coming from different sources. For landslide disaster, 39 scenario-based activities were analyzed with required data according to user needs in a cycle of activities at mitigation, preparedness, response, and recovery phases. Interoperable geographic data model for disaster management (ADYS), enabling up-to-date exchange of geographic data, was designed compliant with standards of ISO/TC211 Geographic Information/Geomatics, Open Geospatial Consortium (OGC), and Turkey National GIS (TUCBS). Open source and free analysis toolbox was developed and tested in case study of the activities such as landslide hazard analysis and disaster warning system to support Provincial Disaster Management Centers of Turkey.
