省级基础空间要素数据库联动更新的设计与实现

Design and Implementation of Provincial Fundamental Spatial Feature Database Linkage Updating

以某省为例,利用GIS技术设计与开发了基础空间要素数据库联动更新系统,阐述了系统的总体设计及系统所实现的功能。系统的建立实现多比例尺间各个要素更新的联动,保证了数据库中地理对象的完整性和数据的一致性,从而为数据库的检索、查询以及分析应用提供方便。

With a province as an example, this paper expounds the design and implementation of provincial fundamental spatial feature database linkage updating information system by utilizing advanced GIS technology. The designing and main functions are introduced in detail. Linkage updating of multi-scale spatial, data can be implemented by development of this system. The scheme is significant to maintain the current spatial data to ensure the integrity of geographical objects and consistency of data in the database, so it is easy to realize database retrieval, query and analysis applications.
