Hi, Sorry for coming late to the discussion. I understand the problem of the complexity of adding indices to the current application. On the other hand, code duplication and modularity have to be taken into account. Some of the indices which are proposed in [1] are not specific to S2. Actually, as I understand it, the only novelty of most of them is the use of the red edge bands, which are also present on other sensors (for instance RapidEye, WorldView, Venus if I am not mistaken). Other indices could also be useful for Landsat, I guess. The current RadiometricIndices application already proposes indices which can't be computed with some sensors. It could also provide the new ones. Maybe this is a good opportunity to refactor the current application to make it more user friendly? I have mixed feelings about the S2 bands resampling inside the application. This is something which can be done by pipelining in memory existing applications (both as a python script or as a composite application). I think a good approach would be: 1. Implement the indices as functors/functions which work on pixel values 2. Add them to the current application (maybe with some refactoring of the app) 3. Build a composite S2-only application which integrates the meta-data reading and the band resampling. What do you think?
