Designing Mobile Geographic Information System for Disaster Management by Utilizing Wisdom of The Crowd

Natural disaster can happen in all region in the world. The disaster can happen anytime and anywhere, the natural disaster is often occurred in the region with a disaster-prone area, especially in Indonesia. Disaster management is needed in Indonesia because the geographic location of Indonesia is a part of the Pacific ring of fire which indicates that there is a potential volcanic activity in the area of Indonesia. Basically, each disaster is treated as a new problem and the response is based on the hastily constructed data. So, even there is a response, a poor decision often caused by inaccurate information. In the digital era, the utilization of information system for daily activity is considered important, especially in disaster management. The purpose of this research is to design a crowd-based geographic information system for disaster management. Simple Additive Weighting Method is used to prioritize accuracy and believable information. Further research can be done to test the system by the different disaster that occurred.
