Abstract
This article presents the impact of digital terrain model quality to basic hydrological analysis. The objects of assessment were the digital terrain model created on the base of contour lines and digital model with terrain skeleton. Comparing the results of basic hydrological analyzes of the two models, the model created only from the contour lines, has been shown to be insufficient to achieve relevant results in hydrological modelling. The aim of this article is to point to the significance of including terrain edges to the digital terrain model, which to serve as a basis for further processing and analyses.
