The world keeps on generating massive amounts of data daily, which lead to the demands for finding new methods to deal with challenges related to `Big Data'. Automatic identification of crops is one of the major applications in the field of the hyperspectral image processing. The major curbs involved in crop classification are: i) Huge dimension of the data and ii) Spectral Similarity amongst crops. This paper proposes a new method of crop classification in which fusion of spectral, spatial and vegetation indices is used as the feature set to overcome the limitation of spectral similarity problem. Here the processing is done in two stages: dimensionality reduction and supervised classification. The dimensionality reduction is done using Principal Component Analysis (PCA) and Minimum Noise Transform (MNF) technique and the selected dimensions are classified using Support Vector Machine Classifier. The results obtained using the proposed technique show that on integrating the vegetation indices along with the spectral and spatial features have raised the accuracy to 98.0749% and helped achieve a kappa coefficient of 0.9769.
