长江下游航道动态数字图形库的建立及应用前景

The Prospect of Building and Application of the Dynamic Digital Graph Database of Yangzi River Downstream Channel

数字长江、数字航道作为数字中国的一个重要组成部分,将使长江的开发、利用及规划、管理产生质的飞跃。长江航道动态数字图形库是建立各类航道管理信息相关属性的有效载体,它的建立必将催生长江航道信息管理系统,成为获取、存取、编辑、处理、分析和显示航道管理动态数据的决策支持,文章就建立长江下游航道动态数据库进行了分析。

Digital YangZi river , digital channel, as an important part of digital China, will make the YanZhi river exploit, use and plan, administration have a qualitative leap. The dynamic data graph database of YangZi river channel is a carrier of building the correlation attribute of diversiform channel administration information, its foundation must make the YangZi river information administration system to be realized, and make it being a decision- make of support of acquiring, accessing, editing, processing, analysis, displaying channel dynamic data. In this paper the building of dynamic data database is analyzed of YangZi river downstream channel.
