As the experience of everyday work shows, some photogrammetry specialists, being professionally focused on the geometric aspects of image processing, may become confused if the software they use to handle multispectral aerial or satellite imagery fails to match the raster channels to the spectral bands. This problem often occurs when new imagery products are introduced into the market and the software is not completely compliant with them or some errors have not been revealed and fixed yet. It may also be caused by the absence of the image metadata. Trying all possible channels-to-bands matches would be a rather time-consuming approach.

The new article of Petr Titarov does not provide an exhaustive survey of the problem; it is merely a case study, which nevertheless may be useful as far as it considers a rather common situation, so the approach described here may be of some help if the routine workflow runs into difficulties of this sort.
