Research on 3D Terrain Modeling Method Based on S-57 Electronic Chart Data

In order to meet the need of terrain model in a ship driving simulation training system, a method of terrain modeling based on S-57 electronic chart is proposed to solve the existing problems. This method integrates three-dimensional terrain data generation technology, GPS positioning technology and GIS geographic information technology, and proposes a method of 3D terrain data generation, radar terrain generation, water depth data generation and navigation object data extraction based on unified data source of electronic chart data. 3D scene terrain data, radar terrain data, water depth data and navigation object data are accurately matched with the electronic chart while ensuring the operation efficiency and fidelity of 3D scene. The results show that the method is flexible and feasible.
