Online mapping is a complex and interactive process,task flow is a new idea and method in interactive cartographical system.The various cartographic models adapted for Web cartographic interaction application are expounded to seek a more appropriate model.In order to make mapping easier in the context of Web,indicator-driven and task flow-centered online interactive mapping model is put forward based on characteristics of statistical indicators and cartography visualization.According to this model the XML schema of online thematic map symbol is defined.Finally,the Shenzhen online atlas is took as a example to show the application of various technique of Web visualization of statistic data based on this model.It shows that the visualization system and model of visualization functions is worth of spreading.
