| Abstract: | In the present study the effect of solar elevation angle on the spectral response of rice crop was examined under farmer’s field conditions. The aim of the study is to see if band ratioing can reduce the effect of soiar elevation angle on rice crop spectral response. It was observed that the spectral transformations involving red and near infrared are highly useful in normalizing the effect of sun elevation when the canopy cover is complete. Contrary to this, the spectral transformation could not normalize the effect of sun elevation on the spectral response of rice crop when the canopy cover is incomplete. |
