On top of that, there is a lot of clutter in those spectral bands, not to mention measurement problems caused by varying reflectivity and light levels between samples taken in the wild
So it isn't as simple as taking a scan and comparing the spectra you measure to a database, there is a lot of noise.
Machine learning/AI models to help with this are quite common in this field, and have been around for decades to help with spectral library lookups - long before the current LLM hype phase.
