Spatial neighborhood relation reasoning based on delaunay triangulation

DU Xiaochu,GUO Qingsheng(School of Resource and Environmental Science, Wuhan University,129 Luoyu Road, Wuhan 430079,China)  
Spatial neighborhood relation is an important spatial relation. It is necessary to distinguish this kind of relation for any spatial modeling system. Delaunay Triangulation, which can represent neighborhood relation between spatial objects expediently, is a triangle partition according to the maximizing smallest angles rule. In this paper, spatial neighborhood relation is represented by Delaunay Triangulation, Based on that, methods of spatial neighborhood relation reasoning are presented.
