摘　　要：地图符号在线编辑器是WebGIS和网络地图制图的关键模块,本文利用RIA技术在用户交互、多媒体表达等方面的能力,研究了基于Silverlight的矢量地图符号编辑器,在分析和建立地图符号模型基础上,着重分析了符号基本图元交互设计、符号图元样式交互编辑和符号的描述规则与存储策略等地图符号在线编辑器的3种关键技术,并建立了地图符号在线编辑器的原型实验系统,实现了地图符号的在线制作、编辑、存储、发布和共享。Map symbol online editor is the key module of WebGIS and Web cartographical platform. With the help of the powerful capabilities of interaction and multi-media expression of RIA technology, vector map symbol editor based on Silverlight was studied in the paper. Based on vector map symbol model for Silverlight, the three key technologies of map symbol online editor, symbol cell inter- design, symbol cell style inter-edit, and symbol description rule and storage tactic, were analyzed. Finally, an experiment of map sym- bol online editor was built to implement the online designing, editing, storing, publishing and sharing of map symbol.
