The landuse is the basic spatial data for the modelling of evapotranspiration in a hydrological model that was developed in the study area. The results of the classification show that the biggest part of the study area is covered by deciduous forest (32 %), followed by grassland (19 %), shrub (19 %), agricultural areas (18 %), coniferous forest (10 %) and areas with no or sparse vegetation (2 %). The advantage of using classification is its fastness in acquiring new data and its ability to determine user-defined classes that incorporate vegetation types according to their influence in the hydrological cycle.
