基于Voronoi图D-TIN CORS参考站网络的自动构建与空间关系组织

Reference Stations Network Automatic Construction based on Voronoi D-TIN and spatial relations structure

连续运行参考站系统(CORS)在进行数据管理和数据处理之前,必须将离散的参考站按一定的空间关系网络化。目前,其常用的方法是D-TIN,在该方法的基础上提出一种新的自动构建和更新参考站网络的方法:基于Voronoi图D-TIN三角网算法,并以青岛CORS参考站为实例对算法进行验证。而对于网络中的参考站、基线、三角网,采用空间索引机制对三者的空间关系进行统一组织和管理,以便于参考站数据的融合处理。

Discrete reference stations must be networked by some space relations before data managing and processing in CORS.And a new arithmetic was introduced to construct and update CORS Network in Qingdao that it was a Delaunay-TIN arithmetic based on Voronoi.Spatial index mechanism was adopted to construct and manage uniformly the spatial relations of reference stations,baseline and network for integrated data process.
