摘要
介绍了一种新颖的矢量图形可视化方法JVGL(javascript vector graphic library)的基本原理,从地图窗口与JVGL的归一化、地图符号的JVGL可视化实现、对GML的扩展支持等方面分析了将JVGL应用到Web GIS平台上的具体方案,并结合Web GIS网站验证了该方案的可行性。
The fundamental principle of a novel vector graphics visualization method named JVGL is introduced. The concrete approach of applying JVGL to Web GIS platform from these follow aspects: unifying the map window with JVGL, visualization of map symbols using JVGL, the JVGL-extended support to GML, etc. , are analyzed. The feasibility of JVGL method through a practical Web GIS site is testified.
