Aerial Reconnaissance by Web Photogrammetry in Emergency Management

摘要

Measurement techniques by aerial images are effective for the acquisition of spatial information. Aerial images are used for quick disaster recovery and prevention of secondary disasters in the time of a nature disaster. Although automatic change detection is suitable for overview-ing wide areas broadly, an actual damage survey eventually needs human interpretation of images. Web photogrammetry has been developed as a stereo view and measurement environment on a Web browser. This system can be used anywhere with no special knowledge or training in photogrammetry. This paper describes rapid mapping of disaster information by web photogrammetry.
