Several systems for disaster damage mitigation have been studied based on various perspectives. Those previous works suggest it is not easy to get an effective method to comprehend damage conditions due to diversity of disaster damage. This paper discusses a scheme for damage assessment information gathering based on macro and micro perspectives. We, especially, take notice of sensor networks, which play a significant role for the micro perspective. Discussion of this paper for damage monitoring is still open-ended, since unexpected circumstances may lurk in a disaster, and technical environments useful for disaster will even more progress. Moreover, integration of the macro and micro perspectives for damage information gathering should be a significant future work.
