The Indian Space Research Organisation (ISRO) plans to launch a full-fledged niche Earth observation (EO) satellite — called the Hyperspectral Imaging Satellite or HySIS — using a critical chip it has developed.

ISRO is endeavouring to enter the domain of operational hyperspectral imaging from earth orbit with a satellite that can see in 55 spectral or colour bands from 630 km above ground.

About Hyperspectral Imaging
1. Hyperspectral or hyspex imaging is said to be an EO trend that is being experimented globally.

2. It can be used for a range of activities from monitoring the environment, crops, looking for minerals and all the way up to military surveillance — all of which need images that show a high level of differentiation of the object or scene.

3. Hyspex imaging is said to enable distinct identification of objects, materials or processes on Earth by reading the spectrum for each pixel of a scene from space.
