In order to meet the growing demands for 3D digital map applications and enable better un-derstand the multi-level space of cities,a whole-area 3D digital map production has been implemented,among which vehicle mobile mapping service is the key task.This paper proposes a technical solution for road data collection and production using the SSW vehicle laser mobile mapping & modeling sys-tem,based on a pilot project.The colored point cloud data with geographic reference,360° panoramic image data and individual image data is rapidly produced by integrating navigation solution,point cloud correction,image coordinate computation,image blurring processing,point cloud colorization,point cloud noise removal,Orbit GT data production and other processing,and the applicable technical solution for vehicle mobile mapping of 3D digital maps is discussed.The results of this program have been checked and qualified,and have been given free to use by public as the first set of 3D map data for visualization on the spatial data sharing platform(portal.csdi.gov.hk),they were widely concerned and acknowledged by various sectors.So this program can not only be helpful for the promotion of SSW ve-hicle laser mobile mapping & modeling system,but also provide effective reference for similar urban vehicle mobile mapping operations.
