In this study, the effect of urban heat island was analyzed by using the Landsat-5 TM data and knowledge based method based on a case study conducted for the years 2006 and 2009 in Kantarawichai District, Mahasarakham, Thailand. In order to investigate urban heat island (UHI) in the study area, two algorithms were developed, and Surface Radiance Temperature (SRT), Normalized Difference Vegetation Index (NDVI) and Normalized Difference Build-up Index (NDBI) were analyzed. The research employed high-quality solar radiation data acquired from solar-radiation measurement station at Mahasarakham University. The results pointed out that the Landsat-5 TM and knowledge based method are appropriate approaches for illustrating Land use and Land cover changes. |
