Article was presented in 19th MAPIN Conference 2012
After the 2010 eruption of Merapi, some areas at Sleman regency experienced with lahars disaster. Many agencies have their own responsibility to overcome the problems in collaborative work. Nevertheless, it is lack of spatial/GIS data support on their decision making as well as on their communications. The main objective of this research was to identify and develop geodatabase to support collaborative lahars disaster management especially for response and recovery phase of the impact on infrastructures at Sleman Regency. Questionnaires and semi-structured interviews were used to investigate their need of the spatial data and the data availability. The results showed that all decision makers from selected agencies agreed that spatial data is important in their communication. Unfortunately, they are realized that it is practically very limited and not adequate to fulfill their need. Accordingly, several data requirements were identified in this research. The data was collected and organized to develop geodatabase. Furthermore, 67% of respondents stated that spatial data is available in their agencies, but it varied in scale and newness. On the geodatabase development, web feature service (WFS) was implemented in order to support interoperability services through web environment.
