地理空间关系确定性描述与集成推理

Determinate Description and Integrating Reasoning of Geographic Spatial Relations

地理要素的空间关系在GIS空间数据建模、空间分析、地图自动综合等方面起着重要作用,研究如何快速判断要素间空间关系是否发生变化,从而有效维护空间关系具有重要的科学意义。对目前有关地理空间关系确定性描述及其集成推理的研究成果进行综合分析与分类,分析其适应性与特点,并就该研究方向存在和需要解决的问题进行分析。

Spatial relations of geographic dements play the key roles in such fields as spatial data modellng,spatlal analysls,auto cartographic generalization and others. It is of great importance to research on how to estimate whether the spatial relations have been transformed,and thus to effectively protect spatial relations. The research contents and advancements of determinate description and integrating reasoning of geographic spatial relations are analyzed and classified. According to their adaptability and characteristic, existent problems and future research directions are also discussed.
