摘要
对种类繁多的态势符号进行了综合建模,将其划分为单箭头符号、复合箭头符号和多箭头符号三种不同的类型,设计了一套具有扩展余地的态势符号模型,通过组件式GIS二次开发对其进行实现。
In our study, Situation-Symbols were divided into three kinds： single-arrows, complex arrows and multi-arrows, in order to set up different kinds of situation-symbol models. Such situation-symbol models were carried out by expending secondary development of ComGIS. These models include all arrows and could be developed. It is indicated by experiments that these arrows work well on the latform of ComGIS and accord with the demands of situation-map.
