Following the streamlines in Fig. 2, LANDSAT TM/ETM+ images were processed for the mapping of land use/land cover change (LUCC), VIs, LST and heat fluxes. LUCC associated withMay7th 1987 and May 2nd 2000 in the study area was analyzed with respect to the proper interpretation of LANDSAT TM/ETM images and was validated with ground truth data. Regional scale heat fluxes were estimated with the aid of remote sensing images and the surface energy balance algorithm (e.g., SEBAL model) (Bastiaanssen et al., 1998a,b).
