Assessment of storm-induced coastal morphologic changes and damage using repeat lidar remote sensing surveys

Multi-temporal LIDAR surveys provide effective and powerful means to acquire land cover change information for assessing natural hazard damage in a rapid and timely fashion. In contrast to grid cells in the field-based representation, objects are much better information carriers. The object oriented method is efficient for processing repeat LiDAR data, extracting scientific information and knowledge, and providing reliable assessment of hazard damages to support emergency response planning, rescue and recovery activities.
