定性时空推理中空间实体时空变化

Spatial entity’s spatio-temporal change in qualitative spatio-temporal reasoning

采用矩形关系统一表示时空变化和空间关系,在对空间实体平移、缩放等时空变化和实体间拓扑、方向关系之间的约束分析基础上,提出单一空间实体时空变化和实体间空间关系变化相互推导方法。该方法可以增强时空变化的可推理性,有助于空间数据的有效处理和充分利用,对地理信息系统中空间实体时空变化的分析和查询具有一定的指导意义。

With the rectangle relationship between spatio-temporal change and space,we propose a deduction method between the spatio-temporal change and space for a single geography object,based on spatio-temporal change such as translation,contraction,extension,spatial topology and direction.The reasoning ability of spatio-temporal change is improved and the spatial data can be used effeciently.The method can offer some references for the analysis and inquiry of spatial relations and time change in geographic information system.
