摘要：
In view of complex sources and various resolutions of global deep ocean bathymetric data being difficult in fusion to construct high-resolution digital bathymetric model (DBM), we present a MF method (merge-fusion) that is suitable for multi-source bathymetric data fusion in deep waters. Then we apply it to the DBM construction of the "Challenger Deep" in the Mariana Trench. By the workflow of "Merge-Fusion", the method combines electronic charts, multi-beam, single-beam bathymetric data with general bathymetric chart of the oceans (GEBCO) data. It can fill the blank area of data while preserving details in high-resolution bathymetric data. Finally, the constructed high-resolution DBM of the "Challenger Deep" is compared with GEBCO data. The results show that the DBM obtained by this method can better maintain the topographic details. This method possesses important practical application value. © 2019, Surveying and Mapping Press.
