摘要
保持空间数据现势性是保障GIS有效运行的根本前提。本文首先对长期困扰我国城市空间数据库建设的"更新冲突"问题进行了深入分析,然后提出了基于时态的多用户并发更新模式,并完成了系统的设计与开发。实验证明:该系统可以满足城市空间数据库动态更新的需要。
The remaining of the actualities of Geospatial Data is the basic precondition to ensure GIS running effectively. In this article, the author firstly analyze the problem of updating confiiction for the construction of City Geospatial Database in our country that puzzles us long - term, then provide the program of parallel updating for Multi - User based on temporal information, design and develop the system moreover. The experiment proved that this system can achieved the requirement of dynamic updating of City Geospatial Database.
