Remote Sensing-Based Damage Assessment for Homeland Security

摘要: For natural or anthropogenic disasters, rapid assessment is critical for an appropriate and effective emergency response. Remote sensing has served—and will continue to serve—a vital function in disaster damage-assessment activities. This includes disaster-mapping of agricultural ecosystems human settlements, which may involve assessments structural damage, contamination, affected populations. Single- multi-date (change detection) analyses can be employed, a need exploit both spectral spatial information order delineate damage regions from remote sensor imagery identified. chapter provides brief overview some the remote-sensing applications that are utility realm homeland security. Specific attention given sensing-based detection vegetation soil including discussion implications artificial radionuclide as well urbanized areas other settlements.
