摘　　要：在全面分析ERDAS和Sketchup软件性能的基础上,设计了应用ERDAS和SketchUp联合三维建模的工作流程;深入地分析探讨了其中的关键步骤;最后以Geoye-1立体影像作为实验数据,成功地构建了实验区的三维景观模型。试验表明:ERDAS和SketchUp联合三维建模是一套行之有效的三维建模方案,能提高三维建模的自动化程度和效率,满足不同层次要求的三维建模,能为ArcGIS软件的三维建模提供极大的支持,值得在数字三维城市项目中推广应用。On the basis of comprehensively analyzing the performance of ERDAS and SketchUp software,workflow for 3D modeling jointly with ERDAS and SketchUp was designed,some key steps were explored and analyzed in depth,and 3D landscape of experimental area was successfully established with Geoye-1 stereo images.The result shows that modeling 3D urban landscape with ERDAS and SketchUp is an effective modeling program,which could upgrade the degree of automation and efficiency of 3D modeling,meet the requirements of 3D modeling with different levels,provide strong support to ArcGIS on 3D modeling,and is worth to promote and apply in digital 3D city porjects.
