| 摘 要： | 将专题统计数据符号化、可视化地表达于专题地图之上,可使专题地图具有更强的表现力和说服力。现有的专题数据符号化主要以人工方式进行,存在着周期长、工作量大的问题,少量的自动符号化方法又存在可视化效果不佳等问题,针对这些问题,使用＂自由图表＂JFreeChart来构造专题地图统计数据实时符号化系统,实现专题统计数据的自动可视化。实验表明,该方案是可行的,若应用于专题地图制图自动化将具有一定的前景。

| Abstract: | By symbolizing the thematic statistic data as well as visualizing the data on thematic map,the expression of the map could be enhanced and the map could become more persuasive.However,the symbolization of thematic data is mainly done by hand right now which consume lots of time and work,while few automatically symbolize software show poor visual effect.To solve these problems,this paper constructs an system to produce symbols automatically based on JFreeChart.The experiments approved this solution and its application in automatic thematic cartography. |
