it allows to perform spatial measurements by registering the reflection of laser impulse. This method allows to get information about the structure and three-dimensional position of the displayed objects. The resulting point cloud can have different densities (from a few units to several tens of points per sq. m). Each point is adjusted according to the system of geodetic coordinates and then classified according to the client's needs. The final product can be a point cloud, DTM, DSM, 3D model or visualization. Laser scanning allows to obtain information about the size and shape of the object or to model the surface under the treetops.
