摘　　要：开源World Wind可广泛用于海量空间数据管理和三维可视化。针对直接基于World Wind的开源代码开发应用存在的编译麻烦、二次开发不方便及应用扩展复杂问题,本文设计开发了一个海量三维空间数据可视化控件,通过对外部数据库扩展支持使开源控件与业务应用服务集成;进一步采用插件技术设计了一个基于WorldWind的可扩展三维地形可视化应用开发框架。三维数字城市、多维矿产资源数据管理和LiDAR数据快速可视化等典型应用表明,该框架可通过插件式开发方便集成其他应用。Seamless three-dimensional visualization technology of massive geographical data is one of the key technical for CIS, digital city and digital earth applications. A 3-dimensional visualization control was designed and developed based on Open-souree World Wind to solve the problems of compiling and developing directly using the source codes inathe paper. This control could access outer database and make World Wind support customize application. 3-dimension visualization application was developed using the control with plug-in technology, which was proved very useful in 3-dimension digital city, management of multidimensional mineral resources and management of LiDAR data.
