| Abstract: | The highway engineering is the band-shaped structure.Its wide spanning zone and its complex crossing terrain cause the large design quantity of highway selection.Especially during the selection and comparison of many schemes,it is required to invest the great manpower,material resource and financial resources to define the field line.Therefore,the digital terrain model DTM and CAD technology provide a convenient and fast means for the selection of highway line.The article analyzes the application status of digital terrain model DTM and CAD technology,and forecasts its more application in the highway selection field. |
