基于SVG的WebGIS的设计与实现

摘要

SVG具有放缩自如、文本独立、显示效果超强、交互控制性强等优点，在WebGIS中有非常强的适用性。先设计了基于SVG的WebGIS系统总体模型，然后对关键技术脚本动态操作SVG方式做了详细分析，最后对此设计模型在交通及物流行业的应用前景做了简要介绍。%SVG has many advantages such as free zoom,independent text,super display effect,strong interaction control and so on,so it has very strong applicability in WebGIS. The SVG-based overall model of the WebGIS system is designed. The key technologies of dynamic operation method of SVG in the script are analyzed in detail. The application prospect in transporta-tion and logistics industry is briefly introduced.
