The modern technology gives us the possibility to make a Digital Terrain Model, which is more and more frequently used in various scientific fields. Localizing the floodland on the basis of Digital Terrain Model provides an insight into the reality and is relatively quick. On the basis of the materials from photogrammetric flight the Digital Terrain Model was prepared, which was measured at the digital station “Delta”. The model has been supplemented by elements of land cover, that is meadows and pastures, built-up areas, roads, escarpments, forests and waters. By using the software Surfer a spatial (3-D) model of a studied area has been created. The floodland of the Prądnik river, when the water level is higher by 2 and 5 meters, have also been visualised.
