长江水文信息化测绘体系构建与探讨

Construction and Discussion of Hydrographic Information Mapping System in the Yangtze River

本文介绍了长江水文河道测绘体系的发展进程和建设现状,结合长江水文信息化实际需求和“四个水文”发展思路,按照智慧水文的总体要求,构建了长江水文信息化测绘体系总体框架。并在总结、分析现有体系建设成效和存在不足的基础上,提出了进一步完善现代测绘基准、加强海量多源空间数据获取及分析能力、着力解决测绘成果保密与河道信息化工作矛盾等建设措施。

This paper introduces the development process and construction status of the mapping system of the Yangtze River Hydrological channel. According to the overall requirements of intelligent hydrology, the overall framework of the mapping system of the Yangtze River hydrological informatization is constructed and combined with the actual needs of the Yangtze River hydrological informatization and the development idea of “four hydrology”. On the basis of summarizing and analyzing the achievements and shortcomings of the existing system construction, this paper puts forward some construction measures, such as further improving the modern surveying and mapping benchmark system, strengthening the ability of acquiring and analyzing massive multi-source spatial data, and focusing on solving the contradiction between the confidentiality of surveying and mapping results and the work of river information.
