摘要
分析了目前GIS开发与应用的现状以及从底层自主开发GIS矢量图形系统的意义;提出了自主GIS矢量图形系统——DragonMap的设计方案;并就该系统,分别探讨了与其相关的设计思想、内部类组织、文件数据模型、空间数据库模型、属性数据设计、符号库设计等关键技术问题。
The actuality of GIS development,application and the meaning of developing own GIS vector graph system by base development is analyzed. A development method about this system is put forward in this paper. So the development technology ,the class structure ,the file data model ,the spatial database model, the Attribute Data -Design and the technology of Symbol library is introduced.
