DEPENDENCE OF URBAN TEMPERATURE ELEVATION ON LAND COVER TYPES

The purpose of this study is to evaluate the use of Landsat7 enhanced thematic mapper plus (ETM+) data for indicating temperature differences in urban areas and compare the relationships between urban surface temperature and land cover types. The study area is located at Singapore and part of Johor of Malaysia. The ETM+ data acquired on April 28, 2000 was used to derive the urban temperature and the merged temperature color map was generated from the derived surface temperature and the IKONOS image, which is useful for interpretation. The relationships between urban surface temperature and land cover types were analysed afterwards. Our results demonstrate that the image data provide the detailed micro-scale temperature variation. The urban temperature distribution map and the analyses of thermal -to-land-cover relationships can be used as the reference for urban planning and the heat island effect reduction.
