长江航道水下数字高程模型自动化处理系统

Automatic underwater DEM processing system for the Yangtze River

手动处理生成航道水下数字高程模型(DEM)费时耗力,存在着效率瓶颈。提出并构建长江航道水下数字高程模型自动化处理系统。该系统由水深数据自动监测读取模块、DEM自动处理模块、成果自动加工模块以及流程监控显示模块组成,实现了从原始水深点自动监测到规则格网DEM及其专题图的快速自动化处理,有效节省了人工操作,提高了DEM产品的时效性,解决了效率瓶颈问题。

Manual processing of underwater digital elevation model（ DEM） consumes more time and brings efficiency-bottleneck problems. An automatic underwater DEM processing system for the Yangtze River, which is composed of the automatic water depth data monitoring and reading module, automatic DEM processing module,automatic thematic map processing module and process monitoring and displaying module is proposed. The input water depth data could be processed into regular grid DEMs and thematic maps automatically and efficiently by the system. The system can reduce human workload and achieve real-time DEM data processing, and solve the aforementioned efficiency-bottleneck problems.
