Abstract The luminance temperature distribution of Shanghai urban area was surveyed by means of locating, rectifying , image processing, noise erasing, temperature calculating and characteristic extracting from TM infrared data of 8/4,1998. The intensity, spatial structure and cause of UHIE (Urban Heat Island Effect) were investigated and discussed. It is shown that Thematic Mapper data are quite useful for thermal environmental quality appraisal and ecological urban planning.
