| Abstract: | The 1950s technology proposed DEM along with software technology improvement and progress of data source for means, as new technology DEM, for highway survey and design provides a new efficient method. This paper expounds the CASST. 1 mapping system based on the south, Civil3D 2006 software, software as a platform to weft, by establishing digital elevation model （DEM） on road design, and an example is further elaborates the DEM technology in the design of road superiority. |
| Keywords: | DEM contour road design Civil3D software |
