长江航道地形测量数据采集与预处理工作流程优化

Work flow optimization for terrain data acquiring and preprocessing in Changjiang waterway

针对长江电子航道图运行条件下对航道地形信息快速更新的需求,梳理长江航道现阶段地形测量的工作流程,分析了制约实现快速测量的主要因素,结合经验提出提高航道地形测量效率的解决方案和主要难点,为深入研究长江航道地形要素信息快速采集与预处理技术、形成配套软硬件系统奠定基础。

For the requirements of quickly updating of terrain data using in the Changjiang Electronic Navigation Chart, this article analyzes the present work flow of the waterway terrain surveying and mapping and points out some main time-consuming factors. Based on the network transmission technology, systems integration and multi information fusion technology, we present some resolutions and key technologies of improving the efficiency. The analysis of efficiency restriction factors and resolutions for improving efficiency will greatly promote the research on quick acquiring and preprocessing technology for topographic information and the system implementation.
