Zusammenfassung: | The invention belongs to the technical field of port berths, and particularly relates to a port berth navigation bathymetric chart efficient mapping method, which comprises the following steps of 1, preparing data; the water depth point after water depth post-processing is stored in a cloud data end to serve as original data for drawing, and water depth point data is formed; 2, constructing a triangulation network according to the water depth point data, and forming a berth water depth model; 3, inputting an old berth map, and extracting the position of each water depth in the old berth map to form an old fixed water depth coordinate model; step 4, making a final graph-loaded bathymetric map; and sampling on the old fixed water depth coordinate model by using sampling point software to obtain a grid water depth model. The efficient mapping method for the port berth navigation bathymetric chart has the advantages that finished berth bathymetric charts can be automatically manufactured and output in batches, on |
