Based on research on information organization and visualization mechanism of multimedia electronic map,this paper proposes an organization method about spatial information and multimedia information of multimedia electronic map:seamless spatial data were organized and managed by stratified expansion R-tree and Quacl-tree hierarchy;and multimedia information data were organized and managed by hypermedia model based on an electronic map.Considering electronic map features,the paper also proposes a method for spatial date organization,which integrates Digital Landscape Model and Digi-tal Cartographic Model,and a hybrid model between vector and raster spatial data.Then,the paper studies information visu-alization mechanism of multimedia electronic map.Finally,the paper certifies the results via a case of multimedia electronic map authoring tools software-Atlas2005.
