Applications of 3D measurement with ground laser scanner

The 3D spatial visualization by computers become common nowadays as it is represented by computer games. There are so many applications of the 3D geographic information. However the data providing methods are not enough for the 3D representation. Laser measurement is the one of data providing technique on this point. We tried to discuss the problems that occur in the actual data providing process. Two cases are presented by this paper is the areas of recreating urban street space and grasping the situation of disaster site. For the former case, there is no problem for the ground laser scanner in measurement but insufficient development of software as the modeling tools. For the latter case, it shows that the ground laser scanner is an efficient way to understand the situation of the disaster sties instantly and functionally.
