基于Voronoi图的空间邻近定义与查询

Spatial Adjancency Query Based on Voronoi Diagram

  • 摘要: 首先在点Voronoi图的基础上,引进了空间目标的Voronoi图的定义,进而论述了空间目标Voronoi图在GIS中定义空间邻近及其邻近查询中的作用。最后给出了部分实验结果。

     

    Abstract: First at the base of point Voronoi diagram,the definition of the spatial object's Voronoi diagram is brought forth. Then according to spatial object's Voronoi diagram, the definition of spatial adjacency are given and the applications in spatial query are discussed. At last some experiment results are given.
