摘要
具有模糊性边界的空间目标之间的空间关系描述与推理问题在近年来成为GIS界研究的一个热点.本文首先讨论了模糊区域的边界问题,然后把Egenhofer等描述确定性区域的9交模型引入到模糊区域,建立了二维空间中描述模糊区域之间的9交模型,最后提出了基于空间方向关系和空间拓扑关系的组合推理方法.
Spatial description and reasoning of spatial objects with indeterminate boundaries is a hot issue in GIS in recent years. This paper firstly discuss fuzzy region boundaries question, then introduce Egenhofer describe crisp regions 9-intersection model to fuzzy regions. The description in 2D space between fuzzy regions 9-intersection model was founded, in the end, the combinational reasoning ways was proposed based on spatial direction relationships and spatial topological relations.
