随着移动通讯以及无线互联网技术的发展,人们可以随时随地从移动互联网得到任何信息.移动客户端(蜂窝电话,PDA以及车载终端等)的异构,要求移动GIS在空间信息的表达上必须采用开发的标准描述形式.可缩放矢量图形(SVG)是目前表达空间信息的一个重要标准,Mobile SVG可用于移动GIS系统中空间信息的表达.在分析空间信息和SVG标记之间映射关系的基础上,设计了SVG表达的空间信息的生成方法以及利用拉模式的解析与渲染方法.实验结果表明:采用SVG表达空间信息的方法具有较好性能,能够解决移动空间信息服务多样化的问题.

With the development of mobile communications and wireless Internet technology,people can get information needed at any time and any where from mobile Internet.As the mobile devices including cell phone,PDA,as well as in-vehicle terminals, etc,which are heterogeneous,then the standard methods to describe mobile GIS information on expression must be developed. Presently,Scalable Vector Graphics(SVG) is an important standard to express spatial information,and compressed version of SVG (Mobile SVG) can be used in mobile GIS systems.Based on the analysis of mapping of spatial information and SVG tags,the paper designs the generation and rendering method of SVG based on pull mode.Experimental results show that the method pre-sented in the paper has better performance on expression spatial information,and solve the issue of divemifieation mobile infor-marion services.
