An airborn laser scanning is a basic for topographic plans and three-dimensional models of constructions

An Airborne laser scanning allowed to get the cloud of points with clearly defined spatial coordinates. If that cloud is classified, the various models could be created based on received information. Nowadays, 3D models of buildings are used in a variety of industries for analysis and different processes development forecasting, connected with buildings. It explains why the methods of creating 3D models should be researched and algorithms of its developing should be created. The Airborne laser scanning is researched in the paper, analysis of data (the cloud of points) processing is done in programs that allowed to create information system.
