Sažetak
Using NOAA/VHRR satellite images during one year period and monitoring changes of Normalized Difference Vegetation Index (NDVI)and variations in multispectral feature space, occurrences of phenological phases for the oak-wood (Quercus robur) in five lowland locations in the Republic of Croatia was noticed. Average annual variation of NDVI was computed along with criteria for detection of the most distnct phenological phases. Changes in the multispectral feature space were noticed and using of dynamic clustering was suggested for determination of time-dependent features. This method could be used for monitoring oak-wood, which are not included in agrometeorological network in Croatia and even in neighhbouring countries.
