This elaboration shows how to use Height Data by using airborne laser scanning (ALS) to delineation of flow lines which let to evaluation of water’s flow on terrain. Maps, which show flow lines, were generated by using GIS software and tools on testing areas. To achieve this goal were used methods of a single flow direction and multiple flow direction. Created maps which show directions of runoff, generated based on the DTM, were subjected to analysis. On the basis of these maps were evaluated the accuracy of determination of the flow direction on the testing areas by using individual algorithms. Studies determining directions of runoff can and do have large application. They will serve the author as initium to create a network of watercourses needed to convert 3D image. This model of the network 3D will be an attempt to create a component BDOT10k in the form of three-dimensional.
