Prispevek prinaša pregled in primerjavo zmožnosti zaznavanja vodnih objektov ali vodnih površin z različnimi sistemi daljinskega zaznavanja: optičnimi in radarskimi satelitskimi senzorji ter optičnimi senzorji na letalih. Zmožnosti zaznavanja vode ocenjujemo z več vidikov, in sicer razlik v prostorski in spektralni ločljivosti posnetkov, zahtevnosti predobdelave in priprave posnetkov, načina obdelave oziroma analize posnetkov ter ustreznosti podatkov za vrsto in namen kartiranja. Pozornost namenjamo tudi vrednotenju uporabnosti podatkov daljinskega zaznavanja glede na uspešnost zaznave območij vode v heterogeno strukturiranih okoljih ; This article presents a review and comparison of the detection capability of water facilities or water surfaces with different systems of remote sensing: optical and radar satellite sensors, as well as optical sensors on aircraft. The capabilities of water detection are estimated from several aspects: differences in the spatial and spectral resolution of imagery, the complexity of imagery pre-processing requirements, and the method of analysis and interpretation feasibilities for the type and purpose of mapping. Particular attention is paid to evaluating the applicability of remote sensing data in light of the detection efficiency of water areas in heterogeneously structured environments.
