Remote Bathymetry with a Multispectral Active/Passive Airborne System

Abstract

Active/passive multispectral data collected at 1000 ft to 10,000 ft altitudes in the Bahamian Calibration Area were processed in order to construct bathymetric charts and images of the bottom reflectance. Preprocessing methods were developed to correct for sunglint and atmospheric attenuation effects as a function of scan angle. While depth charts can be made with ship measured control points as well as band ratio techniques, lidar time differences measured at 1000 ft altitude were found to be the best source of water depth calibration input data needed to identify parameters for extrapolation of water depth measuring techniques to higher altitudes.
