摘要
目前如何处理地理信息随时间变化的动态特性成为GIS的重要研究方向之一。本文设计和实现了用于多时相空间信息几何特征、属性特征、属性专题统计特征的动态可视化的一些方法,建立了一套矢量动态符号库用于在地图上展示时空数据的几何和属性信息随时间变化的动态特性,实现了一组专题统计动态图表用于展示时空数据的属性专题统计结果随时间变化的动态特性。
Presently,the research of dealing with the dynamic properties occurring with time in geographical information has become an important topic in GIS.The main contribution of this paper included three aspects: first,some dynamic visualization methods were designed and implemented for geometric features,attribute properties and thematic statistical features of multi-temporal spatial data;then,a set of vector dynamic symbol library were established to display the dynamic characteristics of the spatial and attribute information of spatio-temporal data in map;finally,a series of thematic dynamic statistical diagrams were utilized to display the dynamic characteristics of the thematic attribute statistical features of spatio-temporal data in map.
