GIS数据库更新信息自动传播软件工具设计与实现

Design and realization of software tool for automatic update propagation between GIS databases

针对现有GIS软件工具缺乏相应的功能模块,不支持批处理,需要大量的人机交互,不能满足GIS数据库更新信息传播自动高效要求的缺陷,采用ArcEngine组件技术设计实现了一个专门的更新传播工具。该工具通过自动地执行更新传播过程中的模式匹配、变化提取、更新集成等操作,能够有效地提高更新传播的效率,弥补现有软件的不足。

Aiming to the limitations of the existing GIS software,such as lack of the corresponding function modules,no supports of the bulk processing,a lot of man-machine interactions,inability to automatically and efficiently implement the update propagation,a special tool for the update propagation is designed and realized based on the component technology of ArcEngine.This tool can enhance efficiency of the update propagation and overcome the limitations of the existing software.The operations such as schema matching,updates extraction,updates integration,can be performed in an automatic batch mode.
