Is there any standard procedure/sequence of tools to process the hyperspectral tabular data before PLSR regression modeling.
example of tools are 1) De-resolve 2) second derivative 3)normalize 4) de-trending 5)baseline etc.
Application is for field spectroradiometer data of soil and crop.
Or the sequence of tools differ for different datasets ?

The pre-treatments you use will depend on the sample set: noise, level(s) of analyte, number of samples, ranges, etc. In many cases, it is a case of start small (Absorbance data) and add treatments, as needed. Just remember, every treatment can hide/generate peaks and will have an effect on sensitivity.
