Abstract

Significant changes in urban environmental characteristics such as altered land use and a higher population density contribute to the formation of the urban heat island (UHI) phenomena. Remote sensing technology and Geographic Information Systems (GIS) have now become effective tools for analysing the UHI phenomenon. This research uses the literature review method. The objectives of this study were to review: 1) General studies of the UHI phenomenon, 2) UHI studies in the context of remote sensing and GIS, and 3) Application GIS and remote sensing to examine the connection between surface temperature and land cover in the context of urban heat island effects. The UHI is formed related to the change in urban structure and land cover, such as an increase in building and road surfaces and a reduction in green open areas. The UHI phenomenon has significant impacts on thermal comfort, air quality and energy efficiency in urban areas. UHI measurements can be made by analyzing Land Surface Temperature (LST). LST can giver information on change in time and space of the Earth’s surface temperature. This review can offer a more thorough comprehension of the variables influencing UHI. and its impact on the urban environment as well as a collection of technical remote sensing and GIS methods that can be applied to map the UHI phenomenon.
