Abstract:Disaster Management especially pre disaster management, the early warning phase, is critical due to its importance to potentially save human lives. One of the crucial tasks in this phase is to obtain timely and accurate geospatial information to be able to quickly visualize and understand the situations (Rocha et al., 2005). In this context, a map-based Geowebservice was developed as control room as a part of early warning system. The system application integrates geospatial services, Web Map Service (WMS) and mapping mash up to provide an interactive and user-friendly interface. The objective of this research is to design, create and evaluate a map-based Geowebservice which integrates different data streams and acts as a control room to monitor potential natural disasters as part of early warning. It is built for scientists to report the current situation to the decision makers to warn them earlier and assist them in their actions regarding their response to the crisis situation. Why map-based Geowebservice? It is because maps are tools to represent the abstraction of the reality. Maps can display the current situation at hand. The problem is how to display the information in such a way that maps can give all the information needed in short period of time. In addition, how the interfaces of the Geowebservice should look like? This research tries to design a suitable interface for that kind of situations. Two alternative interfaces were built. First interface was based on the concept of multiple linked views which is static and has a fixed layout, while the second was based on the concept of pop up window to display the information. A prototype based on the design was built as the proof of the concept. The use case chosen is the volcanic activity of Merapi volcano, Jogjakarta, Indonesia. Usability evaluation was carried out to test the prototype functionalities and to know which interface is more preferable by the users. Five Geohazards students were chosen as the participants. The technique used to conduct the usability was thinking aloud followed by the interviews. The results of the evaluation showed that the prototype was effective, efficient, and satisfied for most of the users.
