分析、总结了GIS技术与三维建模技术的特点,在此基础上提出了一种高效的基于地理信息系统开展建筑物三维建模的技术方法。即采用草图大师三维建模模块实现建筑物3D建模,并利用其与ArcGIS软件的接口,将其植入ArcGIS系统中,构建规模化的城市建筑的三维数字化应用模块,实现3D浏览和应用;同时重点探讨了建立应用模块的三维模型结构化方法,3D文件的组织与管理以及三维数据高效缓存技术处理细节。 更多还原

【Abstract】 The paper presented the cost-effective methods of building 3D modeling based on geographic information systems through analyzing and concluding the characteristics of GIS technology and 3D modeling.That was using Google SketchUp for building 3D modeling,and the modeling will be implanted in ArcGIS system by using ArcGIS software interface,to construct 3D application modules of large-scale of the urban architecture,which can achieve 3D application and view;also focused on the structured approach ... 更多还原
