GAF AG has developed and successfully demonstrated a new innovative approach for deriving bathymetry from space. With this method, GAF can generate bathymetric maps covering large areas by simultaneously using differential spectral attenuation and stereo-information from satellite imagery. The approach only requires the use of satellite stereo imagery with precise ephemeris data and is therefore not dependent on ground truth data like echo sounding or lidar depth measurements. As such time consuming and costly in-situ measurements are not required, the technique is more flexible and cost-effective than traditional approaches. This method has recently been used, for example, to successfully map
