Choosing between the traditional UHI index classification and the alternative classification (0.20) for studying the urban heat island effect in a tropical region depends on factors such as data resolution, local climate, research objectives, and the need for comparative analysis. Higher resolution data and focusing on nuanced temperature variations may favor the traditional classification. At the same time, broader patterns of UHI across more significant regions might be better captured by the alternative classification with wider intervals. Considering the study area's specific research goals and characteristics is crucial in selecting the most suitable classification scheme to provide meaningful insights into the UHI phenomenon.
