WEB-BASED SPATIAL INFORMATION SYSTEM TO SUPPORT COLLABORATIVE LAHARS DISASTER MANAGEMENT

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 develop spatial information system 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. Basically respondents agreed that spatial data is important in their communication and decision making support. Specifically, the application is utilized with specific spatial analysis tools to support decision making processes. The users’ evaluation of the prototype resulted that almost all of respondents give a good mark to the system.
