基于NetTopologySuite在Microstation v8中构建拓扑的改进方法

Based on NetTopologySuite improvements in Microstation v8 build topology

Microstation的v8版本中虽然已经能够建立拓扑关系,但是仅仅是实现了能从线构建面等简单的功能,而不能做各类高级的拓扑运算。同时Microstation中并不存储图元的附加属性数据,造成了无法实现空间叠加分析。本文引入了开源的拓扑分析库NetTopologySuite,使用C#语言位Microstation开发相应的拓扑分析模块,使得Microstation v8能够在保持内部数据结构不变的情况下进行更复杂的拓扑运算和空间分析。

though Microstation v8 version has been able to build topology relationship, but it is achieved from the line to build the surface such as a simple function, and can＇t do all kinds of advanced topological arithmetic. At the same time, the primitive is not storage in Microstation attribute data, caused a unable to realize spatial overlay analysis. This paper introduces the topology analysis of the open source library NetTopologySuite, using c # language Microstation development corresponding topological analysis module, make Microstation v8 under the condition of invariable in keeping the internal data structures are more complicated topological arithmetic and spatial analysis.
