In collaboration with the Vienna University of Technology and the University of Stuttgart, Roland Schwartz and colleagues from the RIEGL research team were able to demonstrate a new and innovative model in underwater topographic mapping with the SVB (surface, volume and floor) algorithm. A significant advantage of their method is that it relies on only one laser wavelength. The jury was impressed with the precise modeling of the return waveform, the clarity of the description, the convincing experimental results, and the potential for wider application of the method.
