Denpasar city with a large population and urban size located in the Bali province, Indonesia, was chosen to study and quantify the entire urban heat island (UHI) as a continuously varying surface and its spatial expansion. Extensive urbanized surfaces modify the energy and water balance processes and influence the dynamics of air movement. Landsat 5 TM and 7 ETM+ images of Denpasar on 1995 and 2003 were selected to retrieve the brightness temperatures and urban heat island areas. The purpose of this study was to characterize the complete urban heat island in magnitude and spatial extent without the use of in situ measurements. The result showed in the center of the city that has density built up area created high surface radiant temperature in both observation times. Temperature changes are quite large due to the addition of population size and land use land cover changes. Vegetation abundance from urban forest or holy area has an important role controlling the cold surface radiant temperature in the center of city. The cross section analyses indicate that the land surface temperature (LST) intensity decreases gradually in the central parts of the city towards the surrounding. Indicated UHI effect may have occurred in Denpasar.
