The NDVI data set is used for the estimation of evapotranspiration. Evapotranspiration in paddy fields is estimated using the solar radiation method instead of NDVI. The estimated flux by NDVI and solar radiation method is compared with single layer model as physical method. As a result of the comparison, the singlelayer model method shows smaller evapotranspiration. Considering the evaporation by canopy interception in singlelayer model, evapotranspiration estimated by both models show the near value in forest area. NDVI method shows smaller evapotranspiration in city area. We understand that NDVI method underestimates evapotranspiration in city area. However, distribution pattern is quite similar and it concludes that NDVI method could estimate evapotranspiration.
