Abstract. Disasters such as floods, large fires, landslides, avalanches, or forest fires are often inevitable and cannot be fully prevented, but their impact can minimized with sound disaster management strategies aided by the latest technological advancements. A key factor affecting these is time, where any delay result in dramatic consequences potentially human losses. Therefore, a quick situation report of highly demanded, still not an easy task because - most cases priori known spatial...
