Research on GIS-Based Open Simulation System for Visualization of Complex Underwater Environment

With the rapid development of science and technology, marine resources are receiving increasing attention. However, due to the special nature of the marine environment, it is difficult to achieve autonomous marine protection as well as efficient management by human resources alone, which seriously restricts the exploration and development of marine resources. To address this need, the paper proposes an open simulation system for visualizing complex underwater environments based on Geographic Information System (GIS). The system firstly realizes the 3D visualization of underwater topography; secondly, the rendering of hydrographic data is realized in the front-end interface. The results show that the simulation system for the visual representation of complex underwater environment is more suitable for realistic scenarios, and in the process of obtaining effective marine data, it can effectively avoid the influence of disturbing factors such as turbid water and insufficient light.
