Hyperspectral Imaging for Earth Observation: Platforms and Instruments

Hyperspectral imaging is one of the promising remote sensing techniques. This technique records the spatial and spectral information of the object under study. Consequently, it has been gaining momentum in a number of Earth observing applications. The aim of this paper is to present the current trends of hyperspectral sensing from different platforms and instruments for various applications. For Earth observation, mobile platforms are discussed which include spaceborne, airborne, ground-based sensing, unmanned aerial system, and underwater vehicle-based. Under these different sensing platforms, hyperspectral imaging instruments are presented that have been developed by various public and private organizations in the past with some specific goals.
