Modern geomorphological analyses largely benefit from GIS tools developed for landform and landscape mapping. Semi-automated methods with the use of public domain elevation datasets ensure the mapping of large areas with relatively low time and cost requirements, leaving less space for subjectivity. For our analysis we chose the geomorphons approach, a robust cell-based method to identify landform elements at a broad range of scales. Based on the delineated landforms and auxiliary morphometric parameters it was possible to map the geomorphological landscapes occurring in Hungary with the supervised classification algorithm implemented in the GeoPAT toolset. The scientific output of the presented work is twofold: one aspect is the creation of an objective and quantifiable map of landforms and geomorphic landscapes of Hungary, while the successful application of the available methodology and the evaluation of SRTM1 model’s applicability for geomorphological purposes are also significant results.
