New effective and economical airborne and space-borne methods for bathymetry determination (seafloor mapping)

Continental shelves make up about 8% of the entire area covered by oceans and seas and the remaining parts have a poorly defined sea bottom. Therefore, it is necessary to find efficient and preferably coast effective methods of bathymetry determination. One of the most efficient and the least expensive method is satellite derived bathymetry (SDB). Acquisition technique of bathymetric data has evolved from a shipborne platform to airborne and spaceborne acquisition. In this article we deal with Satellite Derived Bathymetry technique (SDB), as relatively new survey remote sensing acquisition technique method, which uses high-resolution multispectral satellite imagery or other remote multispectral imagery for depth determination in the coastal area of the middle Adriatic. The result of satellite derived bathymetry (SDB), which used free of charge Sentinel 2 image taken on 09th May 2017, for depth determination in the area of the Hramina Bay was shown.It can be concluded that in the coastal shallow part of the central and southern Adriatic, due to its high transparency, can be applied numerous techniques of bathymetric survey such as LIDAR, SDB and SAR using aeroplanes, helicopters, satellites and unmanned aerial systems (UAVs) of all types.
