宽边界区域和简单区域间拓扑关系的表示及推理

Representation and reasoning for topological relations between simple broad boundary region and simple region

基于RCC5得到宽边界区域和简单区域间的交集模型,根据宽边界模型的约束条件提出算法,并得到11种可以实现且完备的拓扑关系。本文所建立的宽边界区域和简单区域间的表达和推理模型,可用于表达和预测台风风圈区域和特定岛屿地区间的拓扑关系,对岛屿地区抗台风预警机制的建立具有一定的指导意义。

An intersection model between a simple broad boundary region and a simple region is proposed on the basis of RCCS. Based on the constraints of the simple broad boundary model an algorithm is developed, by which 11 achievable and complete topological relations are obtained. This paper establishes a model for representation and reasoning of the topological relations between a simple broad boundary region and a simple region. This model can be used to represent and predict the topological relations between typhoon wind circle area and specified island region. This method may provide guidance for anti-typhoon warning mechanism in island region.
