What characterizes hyperspectral imagery?

Hyperspectral imagery is characterized by its ability to capture a vast range of wavelengths across the electromagnetic spectrum, often including hundreds of narrow and contiguous spectral bands. This extensive range allows for the detailed analysis of materials and phenomena based on their spectral signatures. Each individual band captures specific wavelengths of light, and when combined, these bands provide a rich dataset that can be analyzed to identify materials, monitor environmental changes, and detect subtle variations that might not be visible in traditional multispectral imagery, which typically uses fewer bands. The wealth of information obtained from hyperspectral data makes it exceptionally useful in various fields, such as agriculture, mineralogy, and environmental monitoring, where precise material differentiation is crucial.
