| Περιγραφή: | Remote sensing has become an effective tool for acquiring coastal data over the last decades. Algorithms, such as cBathy or UBathy, have enabled the derivation of bathymetries through the observed wave propagation using videos from, for example, fixed stations or drones. In this work, we explore the potential use of these techniques for satellite video. For this purpose, departing from uBathy, the nearshore bathymetry at Castelldefels beach (Barcelona) has been estimated using three 45-seconds satellite videos captured at 10 fps and with a spatial resolution of 1 pixel per meter. The results were compared against those of the fixed video monitoring station at Castelldefels beach (coo.icm.csic.es). Additionally, an echo sounder bathymetric survey is used as Ground Truth for validation. The obtained bathymetries from a single satellite video, with favourable wave conditions, are considered successful and almost equivalent to those obtained using 10-minute fixed station videos. |
