For the past two decades, hydrographic surveyors have used Optech's bathymetric laser technology to accurately measure water depths and to describe the geometry of the shallow-water seafloor. Recently, we have demonstrated the potential to produce bottom images from estimates of SHOALS-1000T green laser reflectance, and spatial variations in the optical properties of the water column by analyzing time-resolved waveforms. We have also performed the electronic and geometric integration of an imaging spectrometer into SHOALS, and have developed a first generation of software which provides for the exploitation of the combined laser and hyperspectral data within a fusion paradigm. In this paper, we discuss relevant sensor and data fusion issues, and present recent 3D benthic mapping results.
