Abstract
The invention discloses a submarine topography construction method based on multi-source water depth data integration, which achieves reasonable splicing of various data such as multi-beam sounding, single-beam sounding, historical topography map and global topography and submarine topography construction. The invention comprises the following steps of: converting a historical submarine topography map into grid data, converting water depths of other sources into grids, using an overlapping and contrasting method to evaluate the accuracy of the water depths of different sources; using a multi-map-layer method to carry out integration, cutting and splicing on multi-source water depth data, constructing an error distribution model to reasonably revise and integrate various-source water depth data; and constructing multi-source water depth submarine topography and grid. The submarine topography construction method has the advantages that in marine mapping and charting process, the multi-source data can be effectively used, the historical water depth data accuracy and the comprehensive utilization efficiency are promoted, and the submarine topography construction method has important pr…
