Abstract: Bathymetric measurements by remote sensing has many attractive characteristics such as speed and detailed mapping of large areas. One method to measure depth of water bodies by airborne laser scanning (ALS) is to to measure the water surface with an infrared laser and the bottom with a green laser. Current sensor systems routinely acquire and store the full ALS waveform, allowing to do bathymetry with a single green laser only. In this presentation it will be shown how the full waveform can be used to reveal an estimate of the surface and bottom position of water bodies with less bias than traditional methods and that it is important to know the true position of the water surface for the measurement of the bottom.
