Mapping Urban Heat Island areas and Changes in Lagos Metropolis, Nigeria

Ibeabuchi Uwadiegwu, Feyi Oni, Olusegun A. deaga

Abstract


Many urban areas experience elevated temperatures compared to their outlying rural surroundings; this difference in temperature is what constitutes an urban heat island. Geographical Information System (GIS) and remote sensing techniques were used to map urban heat island areas and changes in Lagos metropolis by considering the following data which include urban and rural built up (derived from the urban landscape) and Land Surface Temperature (LST). Urban Heat Island (UHI) areas were determined for Lagos metropolis by creating an urbanized area to delineate the urban built-up area from the rural built-up area, with reference to LST mean. While Urban Heat Island (UHI) changes were mapped using the area extent covered by heat island in Lagos metropolis over time for 1984, 2000 and 2013. Based on research findings, possible mitigation measures as means of controlling the menace of Urban Heat Island (UHI) were highlighted for the study area.
