一种面向海量基础地理信息数据更新的多人协同作业方法

为解决传统面向海量基础地理信息数据多人协同更新技术方案中存在的问题,满足实际生产中对作业效率、过程数据管理等要求,本文提出了一种多人离线协同作业方法。该方法以扩展的时空数据库模型为基础,通过更新过程中多时态数据的集中存储管理,要素的离线编辑及协同状态维护,协同冲突检测与处理,本地编辑内容提交等工艺方法,实现了多人离线协同更新作业。基于该方法研发了协同作业系统,该系统已在多个省级及以上数据库更新项目中得到了应用,应用效果良好。

A multi-person collaborative operation method for massive basic geographic information data update

In order to solve the problems in the traditional multi-person collaborative update technical solution for massive basic geographic information data, and meet the requirements of operation efficiency and process data management in actual production, this paper proposes a multi-person offline collaborative operation method, which is extended based on the spatio-temporal database model, through the centralized storage and management of multi-temporal data during the update process, offline feature editing and collaborative state maintenance, collaborative conflict detection and processing, and local editing content submission, etc.,multi-person offline collaborative update operations are realized. A collaborative production operating system has been developed based on this method, which has been applied in a number of provincial and above database update projects with good application effects.
