| Abstract: | 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. |
| Keywords: | spatio-temporal data dynamic visualization dynamic electronic map vector dynamic symbol dynamic statistical graphic |
