Hi Sigit,

Near Infrared spectroscopic data for a particular object can be collected either using a Spectroradiometer instrument on the ground (In situ) or it may be possible to extract through high resolution hyperspectral remote sensing data sets. Multispectral datasets may not be helpful in providing details. Another alternative is to check the JPL ASTER Spectral library for various minerals/vegetation spectra that you are interested in. They have a collection of more than 2000+ spectra of natural and human-made materials in the visible to thermal infrared wavelength region (0.4 µm to 25 µm).

Can you also share the details of the literature which you are referring to?

James, thank you very much for your enlightenment.

Your welcome, Sigit. I hope the comments were helpful.
