Laser scanning technology is a spatial information gathering technique which is commonly used all over the world. Systems where the red-light beam are used, are divided into: terrestrial, mobile and airborne scanning systems. The main differences between those are the accuracy, the data acquisition solution (f. e. in ALS and MLS besides of the laser scanner, the inertial navigation system is required) and the covered area in one mission campaign. In addition to a type of the project, the systems could be used and merge as one to create precise, accurate 3D point model of the terrain without any gaps. The data which are provided need up to date. In this paper, authors presented the solution of densing the point cloud from the ALS by the use of terrestrial laser scanning system and low-level aerial photogrammetry to reduce the total costs of filling ALS point cloud.
