Linked to GPS so position is known. Lidar land-sea interface. Physical limitation to what you can do over water because light is poorly returned to sensor. Survey can extend on both sides of water line. No backscatter for sediment type.
Weather can be a factor for data collection.
Data problems such as repository, archiving and distribution must be resolved before data collected. Interest in Tsunami modeling is highest in developed areas with sharp water interface. Difficult to merge these data sets. The panel felt that money might be better spent on a new survey. Jetski and ATV with GPS are being used to collect near-shore lidar along a segment of the beach in southwest Washington.
