【摘要】 介绍了一个基于VC++和OpenGL的面向城市仿真的VRGIS平台。该平台重点研究了VR与GIS的集成方法和海量数据的支持。在数据上,实现了VR和GIS数据的共享;在功能上,进行了VR与GIS功能有机融合的尝试。支持海量数据的存取和显示,提供了空间分析和路径规划功能,可以应用于城市仿真,为城市规划分析提供决策依据。更多还原

【Abstract】 A virtual city oriented VRGIS platform based on research of the integration of VR and GIS was established.The methods of integration of VR and GIS and the support of Massive data was emphasized.In the platform, a data structure was designed which is shared by VR and GIS.Massive data was supported and some methods of spatial analyses were used too.The platform can be used in city simulation, and afford the information which is used in decision making.更多还原
