Abstract :
Land surface temperature mapping is one of the key parameters in the physics of land surface processes. The present study covers recovering of land surface temperature from space. The study includes the separation of emissivity and temperature by using different methods. It includes computation of radiant and kinetic temperatures of the land features from Landsat 5 TM thermal infrared (TIR) data. Temperature mapping is done with thermal infrared (TIR) daytime and nighttime data. The mapping is also done using spatially improved daytime and nighttime data. As a final note, the findings between the use of improved TIR data and raw TIR data are compared and discussed.
