The regional distribution of thermal environmental elements and thermal environmental index SET^* were estimated from NVl and brightness temperature derived from Landsat TM. The results of analysis on Kinki area were as follows. In the estimation of air temperature, the multiple correlation coefficient using brightness temperature and height above sea level as exPlanation variables was a good result. The surface temperature was estimated from NVl data using the earth surface heat budget. The result of SET^* at 15:00 of typical fine day presented high value in inland area because sea breeze did not reach.
