Analysis of surface temperatures in urban and suburban landscapes from satellite thermal images: A case study of Olomouc and its environs, Czech Republic

Popis výsledku v původním jazyce

The spatial variability of surface temperatures in the urban and suburban landscapes of Olomouc is analyzed in this paper, based on the evaluation of thermal satellite images from LANDSAT 5 (TM sensor) and TERRA (ASTER sensor). The temperatures of activesurfaces were determined by the use of appropriate algorithms. Maps of surface temperatures are presented. The non-homogeneity of the active surface and thus also the relative difficulty of analysis of surface temperatures is documented by the land cover map. The surface field temperature was compared with the values of the air temperature recorded at the weather stations. The analysis showed that the description of spatial differences in surface temperatures of a city and its surroundings, based on anevaluation of the thermal imagery, was inconclusive. The differences reflect the seasons, but above all the nature of the land cover in the suburban landscape. These findings will be used in a study of the temperature regime of Olomouc a
