What is hyperspectral remote sensing? What's the difference between it and traditional remote sensing?

Remote sensing can be divided into multispectral remote sensing and hyperspectral remote sensing.

Multispectral images are remote sensing images that we usually contact most, such as Google Maps or satellite images on Google Earth. Generally, most of them are composed of dozens of bands, and most of these bands are in the visible region, and the band difference is very small.

Hyperspectral remote sensing mainly refers to hyperspectral resolution (
