Hyperspectral imaging is an emerging modern technique in modern remote sensing that expands and removes capability of multispectral image analysis. It takes advantage of hundreds of continuous spectral channels to uncover materials that usually cannot be resolved by multispectral sensing. This book is a collection of research papers of Indian scientist working in the field of hyperspectral remote sensing and spectral signature applications. This has been organized in a way that all these are logically connected and can be referred back and the forth one another for more details.
