摘要
在分析WebGIS中地理信息可视化研究现状的基础上,详细介绍了Java3D开发库的基本开发机制,并讨论其关键技术与解决方案,成功实现了基于Java3D的网络地理信息Web浏览器。实验表明,通过Java3D建立数字球面,并利用Java3D空间数据模型表达地理信息模型,实现在数字球面上映射地理信息,是实现网络地理信息可视化的新途径和新思路。
On the condition of Internet, visualization of geographic information is meaningful and useful. Based on analyzing the situation of visualization of geographic information, this paper introduces the exploitation mechanism of the Java3D library in detail, then discusses the key techniques and resolvent of Java3D. Now a web browser based on Java3D is realized. Experiment indicates that Java3D is a new way and thought for visualization of geographic information on the Internet, because digital spherical surface can be built with Java3D and the spatial data model of Java3D can express the geographic information model. Therefore geographic information can mapping on the digital spherical surface.
