Hi ABraun

Are there ever times when you would not want to transform the data to dB and rather use a linear scale? Can it affect land cover classification in the latter processing steps?

There is no general answer on this, it depends on the classes you aim at and how well these are separable under the given contrasts, also the classifiers might perform differently with linear and dB input. You’ll have to try. Here are some related discussions:

• Estimating Forest Above ground biomass from sentinel imagery using gray level co_occurence matrix - #25 by ABraun
