It would be nice to have a qgis processing algorithm (QPA) that returns the band number or, if available, the wavelenght related to the min/max value of a spectral profile:
The QPA could be named "bandfinder". It should have the following features:
[ ] return a raster of either band numbers (int, 1+), band indices (int, 0+) or wavelenghts (double, units as in the input image metadata)
[ ] allow to specifiy the search range, e.g. "within band 200 to 240" or "within 2300 and 2400 nm"
