Abstract

The thermal field of urban and suburban areas of Wuhan city was derived from TM/ETM+ thermal infrared data, and the results were qualitatively analyzed. Water bodies have stable and uniform thermal field. By normalizing the thermal infrared bands (DNs of thermal infrared band divided by the mean value of water bodies), the two bands of 1988 and 2002 become comparable with each other in thermal value. With the other bands of the same data set, the basic factors affecting the thermal field, namely buildings, greenbelts and water bodies, were identified by visional interpretation or image processing. Contours of the normalized data were calculated for qualitative analysis of the basic affecting factors. The results show that the effects upon the thermal field gradually decrease in order of buildings, greenbelts and water bodies.
