It is recommended to use Band 10 in quantitative analysis because Band 11 is significantly more contaminated by stray light than Band 10. Landsat 5, for example, stopped sending data in November, 2011; Landsat 8 began sending data in June, 2013. Due to cloud cover, less than 10 percent of the datasets were selected for each year, and those images were combined into a single image. In the current study, Landsat-8 surface reflectance Tier 1 data—atmospherically corrected using the LASRC (Landsat-8 Surface Reflectance Code) and Sentinel-2 Level-1C data—were used. The results indicate that in 1986, LST concentrated on the south-western (Bakana) and north-eastern (Oyigbo) sections of the city with temperature range of 19.27°C and 30.17°C having population of 757,022 persons. Land Surface Temperature (LST) is defined by the National Aeronautics and Space Administration (NASA) Earth Observatory as how hot the “surface” of the Earth would feel to the touch in a particular location.. We first derived three types of indices, namely vegetation (VIs), climatic (CIs) and environmental indices (EIs), and resampled them into 30 m using nearest neighbor method and monthly time steps. 2017, 9, 1208 3 of 17 Table 1.
