地理国情监测项目中全集水网数据更新生产方法研究

Research on the Production Method of Updating the Complete Water Network Data in Geographical Condition Monitoring Project

为满足各行业对完整水系网络应用的需求,经水网优化处理形成全国全集水网数据,更新地理国情监测项目近三年水系增量数据后水网数据现势性达到最新。增量数据与水网数据集在空间和属性上的关联和依托关系较为复杂,更新难度大,本文旨在研究一套完整、可行的全集水网数据更新方法,高效、高质完成数据更新。

In order to meet the requirements of various industries for the application of the complete water network,the water network data of the whole country was formed through the optimization of the water network,and the current situation of the water network data was up-to-date after updating the incremental water system data of the geographical situation monitoring project in the past three years.The spatial and attribute correlation and dependency relationship between incremental data and water network data set is complicated,and it is difficult to update.This paper aims to propose a complete and feasible method for data updating of the complete water network,so as to complete the update with high quality and efficiency.
