This study quantitatively analyses the spatial relationship between land surface cover and urban surface temperature distribution among different land use classes in metropolitan Melbourne. This relationship was explored through a detailed estimate of fractional land cover at 30 m grid resolution using LiDAR data along with land surface temperature (LST) and modeled heat fluxes using Landsat TM5 data. In this study spatially distributed energy fluxes specifically ET, in an urban area were modeled based on an energy balance approach incorporating the surface roughness parameters derived from the LiDAR Data. This study shows a strong and significant linear relationship between LST and the percentage of different types of land cover. The relationship is positive for built-up areas and negative for vegetated areas. Such relationship quantitively depicts that with increasing total vegetation cover the LST decreases; in contrast LST increases linearly with increased imperviousness.
