Hyperspectral remote sensing is a powerful technique within the broader field of remote sensing that captures detailed information across a wide spectrum of wavelengths, often ranging from visible to near-infrared and shortwave infrared regions. Unlike multispectral sensors, which record data in a few broad bands, hyperspectral sensors divide the electromagnetic spectrum into hundreds of narrow, contiguous bands. This high spectral resolution allows for precise identification and characterization of materials on the Earth's surface based on their unique spectral signatures. The fundamental principle underlying hyperspectral remote sensing is that different materials absorb and reflect electromagnetic radiation differently at specific wavelengths, producing distinct spectral fingerprints. These fingerprints can be used to detect, differentiate, and quantify a variety of surface materials, including vegetation species, soil ______ ________ ____ _________ __________.
