Weather forecasting has become an indispensable application to predict the state of the atmosphere for a future time based on cloud cover identification. But it generally needs the experience of a well-trained meteorologist. In this paper, a novel method is proposed for automatic cloud cover estimation, typical to Indian Territory Speeded Up Robust Feature Transform(SURF) is applied on the satellite images to obtain the affine corrected images. The extracted cloud regions from the affine corrected images based on Otsu threshold are superimposed on the artistic grids representing latitude and longitude over India.
