This session presents the results from the use of Unmanned Aerial Systems (UASs), Unmanned Aerial Vehicles (UAVs), Autonomous Surface Vehicles (ASV) and Unmanned Underwater Vehicles (UUVs) to gather observations, better assess impacts, determine damage indicators, and understand environmental change. Application of these platforms increase our understanding of natural hazards like tornadoes, hail, floods and hurricanes and human induced hazards such as oil spills and shipwrecks. Terrestrial, coastal zone, and offshore applications will be included. The session is open to all natural and human-induced hazard UAS/UAV/ASV/UUV studies.
