Landforms are important element of geographic classification, typification, and regionalization. The number of methods and indicators for determination, analysis and classification of surface morphological units at different scales has strongly increased with the development of GIS. With regard to spatial joining continuous and discontinuous classification could be distinguished and with regard to values and its limits global and regional classification could be distinguished. In the article we present the method of regional continuous classification and test its suitability in Slovenia.
Several regions extend into the Municipality of Idrija: two European and Slovenian macroregions, four Slovenian mesoregions, as well as numerous microregions. Within the municipality, 17 microregions were defined: ten plateau-like micro regions (the Črni Vrh Plateau, Dole Plateau, Godovič valley system, Krnica Plateau, Ledine Plateau, Ravne Plateau, High Trnovo Forest, Vojsko Plateau, Vrsnik Plateau, and Zavratec Plateau) and seven valley-like microregions (the Idrija Basin, Kanomljica Valley, Sovra Valley, Lower Idrijca Valley, Spodnja Idrija Basin, Zala Valley, and Upper Idrijca Valley).
