轨道交通控制保护区空间数据分析与可视化系统设计与实现

Analysis for rail transit control protected area spatial data implemention for visualization system

为满足轨道交通控制保护区管理对空间数据在线分析与可视化需求,本文采用Teigha组件、.NET sql Geometry类以及OpenLayers包实现了CAD文件读取、坐标内插、空间分析、数据存储以及在线展示功能,在此基础开发了不依赖Auto CAD软件的轨道交通空间数据分析与可视化系统并进行了实际应用,验证了系统的合理性和实用性。

In order to meet the requirements of on-line analysis and visualization of spatial data for rail transit control protected area management,this paper uses Teigha component,.NET sql Geometry class and Open Layers package to realize CAD file reading,coordinate interpolation,spatial analysis,data storage and online display.Based on this function,the rail transit spatial data analysis and visualization system that does not rely on Auto CAD software is developed and applied in practice,which verifies the rationality and practicability of the system.
