Abstrakt CZ: Příspěvek popisuje možnou cestu automatizackého vymezení bázových povrchů v prostředí Geomorfologického informačního systému v oblasti Tučianské kotliny.
Abstrakt EN: The article describes a possible way of automated delimitation of base surfaces in the environment of Geomorphologic Information System (GmIS) in the study area of surroundings of Turčianská kotlina Basin. The article first describes creation of hydrologically correct digital terrain model (with emphasis on sink elimination). Consequently the paper describes an automated delimitation of drainage network with Strahler ordering. From this hierarchical network, base surfaces of second and higher orders are calculated. Also a procedure of possibility of automated delimitation of ridge parts and residual surface is outlined. Above mentioned automatically delimited data layers are afterwards compared with layers manually delimited in south-west part of study area. Based on this comparison, there is discussed the possibility of using automated process in GmIS for expansion to larger areas. Surroundings of Turčianská kotlina Basin has been selected as the study area (the contrast of horsts and scarp graben can be there clearly seen). The Turčianská kotlina is enclosed with circumjacent mountains Malá Fatra, Velká Fatra, Žiar a Kremnické vrchy and their nearby foregrounds. The selected area represents broad spectrum of morphographic types of georelief (from plains to high mountains) and also various georelief forms (from wide and flat alluvial plants to narrow rock ridges). Such a heterogeneous test area allows in-depth examining of used automated processes for base surface delimitation.
