It is the most growing environmental problems in urban areas especially in tropical cities, such as in Jakarta, Indonesia. Jakarta is one of the top ten megacities in Asia that has rapidly growing nowadays. With the growth rate of population is about 1.4% per year from 2000 to 2010, indicates the increasing growth and expansion of our urban centers which entail the construction of new roads, buildings, and other various human made structures to accommodate the growing population, and in turn, the destruction of the natural ground cover and landscape.
This study explores spatial investigation of urban heat island effects of Jakarta, Indonesia in dry season (June – August) from 2006 - 2009. The spatial investigations are analysis of Land Surface Temperature (LST) and minimum air temperatures, estimation air temperature with LST-NDVI (Normalized Differenced Vegetation Index) correlation and determination of hot-cold object fraction images.
The investigations show that there was urban heat island effects occurred in Jakarta for dry season in 2006 – 2009. The analysis of LST and minimum air temperature in Jakarta indicate that urban area of Jakarta had higher land surface temperature and higher minimum air temperature than in rural area outside of Jakarta. The minimum air temperature can be used to fill the gaps of the satellite-based LST. The estimation of air temperature using LST-NDVI correlation also indicates the higher air temperature had occurred in urban area of Jakarta than in rural area outside of Jakarta. The higher hot objects fraction images were also occurred in urban area of Jakarta than in rural area outside of Jakarta. The hot objects displayed a more significant role in influencing LST patterns.
