Word Count : 500
Hyperspectral remote sensing is an advanced technique within the broader field of remote sensing that involves the collection and analysis of electromagnetic radiation across a very large number of narrow, contiguous spectral bands. Unlike multispectral sensors that capture data in a few broad spectral bands, hyperspectral sensors can record data in hundreds of narrow bands, typically ranging from the visible to the near-infrared and shortwave infrared regions. This high spectral resolution enables the identification and characterization of materials based on their unique spectral signatures, which are essentially the specific ways in which different materials reflect, absorb, or emit electromagnetic energy. The underlying principle of hyperspectral remote sensing is rooted in spectroscopy. Every material, whether natural or man-made, has a unique spectral reflectance curve across the __________ _____ _______ _______ ____ ___ ______ ____ ________ ____ _______.
