Effects of Vegetation Cover and Build-up Area on Land Surface Temperature (lst) of Jimeta

This study analyzed the land surface temperature of Jimeta town which is a core factor in the formation of urban heat island phenomenon. Landsat 8 OLI images for the year 2014-2019 were used to determine the changes in land surface temperature of Jimeta over time. Six (6) samples points were selected randomly on NDVI, NDBI and LST where pixel values of each point were obtained. Correlation analysis was used to examine the relationship between NDVI, NDBI and LST. Result of the findings revealed that land use activities in Jimeta metropolis has increased progressively during the years; and this has influenced the urban heat island. Relationship between Normalized difference in Built-up index (NDBI) and the Normalized difference in Vegetation index (NDVI) with Land Surface Temperature (LST) reveal that there is a significant positive correlation between LST and NDBI for which an increase in built-up areas leads to a proportional increase in land surface temperature. NDVI and LST on the other hand showed a significant negative correlation at p
