Risk management of Merapi Volcano has been an important programme conducted by Sleman government in order to minimize damages and casualties. Utilization of spatial data and its technologies is a key for enhanced decision making and coordination in risk management activities. However, the current situation regarding spatial data availability, integration, sharing and its effective application by decision makers at Sleman government agencies have not been optimized. This research aims to implement an application of a Local Spatial Data Infrastructure (SDI) to support risk management efforts, particularly for evacuation planning of Merapi Volcano disaster. SDI is an initiative intended to create an environment that will enable a wide variety of users to access, retrieve and disseminate spatial data resources effectively. One of the essential applications of SDI is geoportals. The study started with a review on activities of risk management of Merapi Volcano. Spatial data needs and roles of the local government agencies were identified. Furthermore, the processes, problems and information flows in evacuation planning were examined. These prerequisites were analysed as foundation for the development of the application. Geocollaboration Portal (Aditya, 2008) was customized in order to provide spatial resources for decision makers when dealing with the evacuation process. It is equipped with usable maps presentation and interaction tools to support collaborative decisions. Finally, user group assessment was carried out to evaluate usability of the application. The evaluation results showed that collaborative portals on top of a local SDI can facilitate effective decision making process and improve coordination among involved stakeholders in the context of disaster preparedness and mitigation. Nevertheless, there are several aspects need to be considered in order to achieve a functional local SDI e.g. availability and quality of the spatial data, establishment of local regulations and standards, development of metadata, and strengthening capable human resources.
