The paper aims to present the generalities and areas of use of laser scanning and its use. Laser scanning technology is among the latest methods of collecting geodata. Is applicable especially in areas which use high precision 3D data. In brief, laser scanning principle is the following: sending a laser beam to measure the distance from the source to the surface or object searched. At the same time, is recorded the direction. By evaluating parameters are obtained information about a specific object on the surface. The laser can be set statically on the ground (terrestrial laser scanning) or a plane or helicopter (aerial laser scanning). For special applications, laser scanners may be located in a vehicle. The main product of laser scanning is a set of 3D coordinates of the points reflected called "point cloud", and with these automatic, semi-automatic and manual procedures, these points are classified by further processing.
