Hi. If you have derived bright temperature from TM6, the next step you should consider the emissivity of each classification( or pixels, or land cover). Sobrino and Qin's algorithms for retrieval of land surface temperature are recommended: 1. Land surface temperature retrieval from LANDSAT TM 5; 2. A mono-window algorithm for retrieving land surface temperature from Landsat TM data and its application to the Israel-Egypt border region. Above articles both deal with single channel of thermal data, and involving emissivity retrieval from NDVI. "By the way, Band 61 and 62, as you probably know, use exactly the same detector I believe (same wavelength and bandwidth) but the gain is set differently (61 is set to 'low' gain, 62 is set to 'high' gain).
