摘要
信息技术、移动计算设备以及WebGIS的发展为电子导游系统的设计与实现带来了新的思路和方法。但是WebGIS在数据组织、数据共享和矢量图形显示等方面还存在问题,在WebGIS中应用SVG和GML技术和规范在一定程度可以解决这些问题。基于GML和SVG的南岳便携式电子导游系统采用包含终端层、应用服务层和数据服务层的B/S结构,GML负责地理数据的组织,SVG控制地理数据的显示。通过对系统评价发现基于GML和SVG的电子导游系统具有运行效率高、交互性强、开发定制灵活等优点。
With the developing of information technology, portable compute and WebGIS, a new solution has been provided to design and implement the E-Guide system. However there are several problems in WebGIS, such as data organization, data sharing and vector data displaying. These problems can be solved by using GML and SVG. The Nanyue portable E-Guide system used B/S structure and there are three layers in the structure： client, application server and data server. Otherwise, in order to maintain better efficiency of interaction, multi-modal interaction has been used. lit is found from the evaluation of system that the system can respond quickly , and has capacity of good interaction and is flexible.
