Abstract
The article introduces the implementation of data acquisition and relative GIS of express establishment based on vehicle-borne 3D data acquisition system. Namely, the stereo images, video images, 3D point cloud data, instantaneous coordinates and attitude of the roads and the geographical objects along them could be captured during the vehicle running on the control of GPS. Through the post-processing software the spatial coordinates can be figured out, and the spatial database, even the GIS of express establishment were founded based on geometric information and attribute information. The application proved that the processed spatial data had good accuracy. The system and application meets the demand of relative users and is worthy to be popularized widely.
