252_CNR-02-04-Ischia_Procida_HR

The DTM was generated from two dataset acquired around Ischia and Procida Islands (Gulf of Naples, Italy). The dataset were collected within CARG (Geological CARtography) Project by means of the MBES system Reson SeaBat8125. The MBES was pole-mounted on a 6 meters long vessel. The MBES has 240 beams 1°x1°; the operational frequency was 455 kHz. A LandStar 12 channel DGPS system was used for ship positioning and a motion sensor Ixea Octans3000 was used to provide corrections for attitude data. A Sound Velocity Sensor was installed near the transducers thus providing realtime sound speed for beam steering. A sound velocity profiler Reson SVP15 was lowered through the water column every 6–8 h to get the velocity profile required for the depth computation. The bathymetric data were processed using the PDS2000 software. Data de-spiking was carried out without the application of automatic filters in order to preserve data accuracy and resolution.
