| Description
| - Nowadays the digital surface model (DSM) is possible to create from a variety of data sources. The laser scanning data rank certain to the very accurate data sources. However, the aims of the paper are introduce another type of data that can not only equal to the data from Lidar but in a case of using it in the applications with large scale it can overcome Lidar data in the accuracy. The photogrammetric procedures have been known for decades. The new technologies make it possible to use these procedures not only for classical aerial photographs, but also for images taken by airplane models (UAV). The contemporary software can simulate the process of creating the cloud of the points also from the stereo-pairs. The UAV models enable to acquire stereopair in a large scale with sufficient accuracy. Then it is possible to use them to generate hundreds of thousands of points for a very small area. In the last phase is necessary to select an appropriate data model and a method for creation the resulting DSM. The TIN model is more suitable for visualization, it can easily adapt to different density of input points. However, the using of the resulting model for other applications (e.g. space-time analysis of surface changes) requires rather regular structure of the grid. The process of creation the resulting DSM cannot be described as straightforward, but it includes the repeated adjustments of the parameter settings. The aim of this paper is to describe at the specific case study the process of the generating the surface from the data with high accuracy and resolution (density) at the large scale model area. The statistically evaluated results will describe the changes in the resulting DSM at various parameter settings during the data preprocessing and processing. This will facilitate the proper selection of the methods and settings also in other similar applications.
