Using a ground 3D laser scanner that uses a pulsed laser, we obtain high definition information on the shapes of our survey targets, such as structures and terrain, in the form of point cloud data that is a collection of 3D coordinates. (Operations are carried out from computers that are connected to high-speed scanners.)

The point cloud data acquired is used not only to measure the shapes of the survey targets, but also can be processed in order to create 3D models or 2D ground plans, elevation plans, and vertical cross-sectional diagrams.
