指标驱动下以任务流为中心的在线交互制图模型

摘要

在线制图是一个复杂的交互过程，任务流是交互制图系统的一种新理念和新方法。分析不同的地图制图模型，根据统计数据和专题地图可视化的特点，提出统计指标驱动下以任务流为中心的在线地图制图模型，并给出网络地图符号XML定义描述，结合某市在线动态专题地图可视化的应用实例，研究基于该模型的统计数据Web空间可视化的各种方法和应用，表明该可视化体系和功能流程模式具有很好的推广价值。%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 apolication are expounded to seeka more appropriate model. In order to make mapping easier in the context of Web, indicatordriven 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, theShenzhen 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.
