摘　　要：基于多维WebGIS的三维互动网络虚拟社区,是基于互联网地理信息系统技术、互联网虚拟现实技术所实现的一项适合在多种网页浏览器上运行的开放式网络三维实景实时交流系统开发平台。研究了WebGIS中多源多维地理数据融合,三维化身与场景的动态融合,海量数据网络调度,以及多用户化身实时互动。系统分为数据预处理、后台管理、前台交互三层模块进行实现,核心模块封装为多维地图表达引擎3GWebMapper与基于Flash网络三维渲染引擎WebFlashVR。Multi-Dimensional WebGIS based 3D interactive network virtual community is a Virtual Real-time 3D network communication systems and Web systems development platform, fitted in running on a variety of web browsers, achieved based on web geographic information system technology and web virtual reality technology. Multi-source Multi-dimensional geographical data fusion of the WebGIS, Scene combination with 3D avatar, massive data network scheduling, and multi-user avatar real-time interactive were researched. System was divided into the data preprocessing, background management, front interaction to achieve. Core of the front interaction module was packaged in the multi-dimensional map expression engine 3GWebMapper and the free olu^-in network 3D renderin~ engine WebFlashVR
