| 摘 要： | 通过对国内外现有三维平台的对比与分析，结合用户对三维GIS的需求，利用开源OpenSceneGraph引擎，设计一套灵活、高效的三维GIS的可视化内核，满足城市级海量三维模型的可视化表现，并集成ArcGIS核心功能，实现三维可视化GIS的管理、浏览和查询分析等功能。案例表明该系统既可延续原有二维功能，也能实现信息的三维可视化。

| Abstract: | Based on the international existing 3 D platform careful comparison and analysis, combined with the 3 DGIS user＇ s needs to discuss how to design a flexible and Graph,support the massive city-level 3D model and efficient 3D GIS core,the system use of open source OpenScene- put forward a 3d visualization of geographic information core per- fiwmance and ArcGIS function combination,to achieve 3 D visualization of GIS, users in the continuation of the original 2D GIS systembusiness functions at the same time,upgrade to 3D visualization interface,truly 3 D visualization of GIS. |
