摘　　要：传统的WebGIS在矢量图形编辑与可视化表达上的不足束缚了网络地图制图的发展,针对这一问题,设计了基于Silverlight的Web地图制图框架体系,研究了地图对象模型设计、矢量地图符号模型设计、地图控件与制图编辑模块设计和基于缓存的制图数据存储策略等4个关键技术。在此基础上构建了实验原型系统。实验证明,基于Silverlight技术的丰富矢量图形编辑与表达能力,能为Web地图制图提供新的技术途径。Traditional WebGIS is weak in editing and expressing vector graphics, which restricts Web cartogra- phy from developing. In order to deal with this problem, a framework of Web cartography based on silverlight was established. Then four key technologies including map object model design, vector map symbol model design, map control together with editing module design and cartography data storage based on cache strategy were analyzed and studied. Finally, an experiment was built to test that Web cartography can work well with the rich vector graphics editing and expression of silverlight.
