ANALYSIS OF SPATIAL AND TEMPORAL VARIATION OF URBAN HEAT ISLANDS WITHIN KADUNA METROPOLIS
ABSTRACT Understanding the spatial variation of urban heat Islands (UHI), will be helpful in urban micro climate studies. This study the urban heat islands of Kaduna metropolis, Nigeria. For the present study Landsat ETM+ images of 2001, 2006, 2009 and OLI 2015 was obtained from USGS of the study area. Normalized Difference Vegetation Index (NDVI) image was developed. The digital number of thermal infrared band is converted in to spectral radiance using the equation supplied by the Landsa...
