摘　　要：为排除传统道路选线方法的局限性,在我国复杂的地形环境中进行经济、合理的道路比选,利用计算机将三维地形建模和二维道路选线相结合,并结合遥感影像,制作出具有真实感的视觉模型,进而对道路选线方案进行可视化分析和评价。实验结果表明,采用三维道路选线方法能有效地进行道路评估,并迅速地发现问题。利用矢量数据和栅格数据结合的数字三维模型进行道路选线,为道路设计提供了新的思路。To eliminate the limitations of traditional line selection method of the road, an economic and reasonable road design in the complex terrain environment of our country was designed. The computer is used to combine 3D terrain building with 2D line selection, and to create the realistic visual model for visual analysis and evaluation on the plan of line selection The results show that 3D road selection method can effectively assess the road, and quickly find the problems. The method using the digital 3D model combined with vector data and raster data for road design provides a direction of road design
