城市空间数据多尺度综合及高效分发关键技术研究——以公交路线为例

Key Technology of a Rule-based Multi-scale Integrated Approach and a Kind of Space Index-based Visiting Mechanism in Basic Frame Data——for example:the city bus routes

以城市空间公交路线的多尺度综合及高效分发需求出发,提出采用基于规则的多尺度综合方法和基于空间索引的高效并发访问机制,并结合ArcSDE来进行实现,提高了信息应用的灵活性和信息共享性。

A rule-based multi-scale integrated approach and a kind of space index-based visiting mechanism are advised for the demands of multi-scale integration and efficient distribution in the city bus routes,and combined with ArcSDE for achieving flexible information application and information sharing.
