Land Surface Temperature (LST) of Lokoja town were retrieved from LandSat TM imagery of 1987. The NDVI and land emissivity were estimated from visible and near infrared bands, while the effective satellite temperature was estimated from the thermal infrared band. The Qin et al's mono-window algorithm was employed to obtain the land surface temperatures of the different land use/cover types in Lokoja town. The result indicated that vacant land and built-up have the highest LST values of 331.13K and 329.82K, and vegetation, water bodies and cultivated land having the least with 294.03K, 296.76K and 306.06K respectively. The average retrieved LST …
