基于Geomedia开发的城市地理信息系统

Urban Basic Geographic Information System based on Geomedia

本文着重研究了大尺度空间矢量数据分类、分层、编码技术，提出了基于实体特征的组合式编码设计方案；研究了Geomedia的二次开发模式与技术，在此基础上，进行了详细的需求分析与设计，以Geomedia为二次开发平台，建立了一个城市基础地理信息系统的原型系统。

This paper brings forward to the solution of full relation,module Urban Basic Geographic Information System based on Geomedia, emphases on the research of large scale spatial vector data about its classification,delamination and coding technique,brings forward to combining code design scheme based on entity characteristic,and studies the second developing mode and technology of Geomedia. Based on the research,this paper carries through detailed demand analysis and design,realizes a prototype system of Urban Basic Geographic Information System with Geomedia as the second developing platform.
