| Abstract: | This article mainly discussed the digital surveying and digital designing in the reha-bilitation and expansion of the existing highway.Firstly,the Hunan Meicheng's reconstruction and extension project of highway background was outlined.Digital photogrammetry,GPS-RTK based 3D data acquisition and digital roadbed model integrated with DTM etc were then discussed.Finally,it was concluded that 1:2000 three-dimensional digital map generated for the paper alignment and DEM establishment can meet the measurement a... |
