Airborne bathymetric lidar (Light Detection and Ranging) systems measure the optical path (range and angle) between the sea surface and the seafloor. Lidar achieves this measurement by firing a laser from an aircraft and calculating the range based on the speed of light and the time it takes for the laser pulse to return. Measurements of photoelectrons at the photocathode of a returned laser pulse...
In 2007 the Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) collected concurrent bathymetric lidar and hyperspectral imagery in Hilo Bay, Hawaii. The data were collected using the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system. CHARTS is JALBTCX in-house survey capability that includes a SHOALS-3000 lidar instrument integrated with a CASI-1500 hyperspectral...
