The Role of Geospatial Technologies in Disaster Emergency Responses

摘要

Geospatial technologies play a significant role in disaster management cycle. The recent large-scale earthquake and tsunami events have demonstrated their uses in post-disaster emergency responses. Remote sensing provides synoptic and detailed data required for emergency and post-disaster responses. It is the unique source of timely data captured in hard-hit and inaccessible areas after a disaster. To respond to a large-scale disaster, the International Charter on Space and Major Disasters shall be activated whereby more space sensors were rescheduled to capture the disaster area, and hence, data availability is not a critical question these days.
