Klasi~na hipsografska analiza je zahtevalaveliko ro~nega planimetriranja in prera~unavanja, z razvojem geografskih informacijskih sistemov in natan~nej{ihdigitalnih modelov vi{in pa je postala pomemben ~len v morfografski analizi pore~ja kot temeljnegeomorfolo{ke enote, saj je realno izvedljiva in dostopna ve~ini raziskovalcev. Kot primer je v prispevku predstavljenahipsografska analiza nekaj zna~ilnih pore~ij v Sloveniji.KLJU^NE BESEDEhipsografija, hipsometrija, digitalni model vi{in, pore~je, geomorfologija, geografija, SlovenijaABSTRACTHypsographic analysis of catchments with digital elevation modelHypsographic analysis of catchments deals with the assessment of catchment properties with regard to elevation.The arrangement of elevations within a single catchment indicates the geomorphologic characteristicsand the prevailing geomorphic processes and landforms respectively. Classic hypsometric analysis demandeda lot of manual planimetry and calculation. With the development of the geographic information systemsand with improved digital elevation models it has become an important element in the morphographic analysisof a catchment as a basic geomorphic unit. Nowadays it could be readily performed and it's accessibleto most researchers. As an example the hypsographic analysis of some typical catchments in Slovenia is presentedin the article.KEYWORDShypsography, hypsometry, digital elevation model, catchment, geomorphology, geography, Slovenia43
