摘要
提出了利用GML对城市地理信息系统进行数据建模和表达的技术与方法。描述了如何利用SVG来实现基于GML描述的地理数据的显示和操作,并且在此基础上建立了基于GML＆SVG的城市地理信息系统的整体架构和设计方案。
This paper brings forward the technology and method to build the data model and data expression of a city's GIS system using GML standard.And the paper also describes the implement of how to display and operate the GIS data expressed based on GML using SVG.Combining GML and SVG,the paper puts forward a solution for the design and architecture of the city GIS system.
