Unexpected results exporting S2 bands as GeoTIFF files

[marpet]

The problem is that the BandSelect operator does not correctly consider the multi-size characteristics of Sentinel-2 data.
As you have found out, adding the Resampling operator fixes this. But for consistency you should not only add it before the 20m bands but also in front of the 10m bands. This should not slow down the processing drastically, because there is not to be resampled actually. In this example I mentioned it:

Split product bandwise into single GeoTiff files

I would like to share an example graph file which shows how to split a product into separate GeoTIFF files. Each GeoTIFF file will contain only one band. How this can be achieved is shown by the example of a Sentinel-2 product, but the approach can be adapted to other products. The example reads a Sentinel-2 L1C product, resamples it to a common resolution and then splits and writes each specified band. Only the bands B1 and B2 are considered in the graph. But it can easily be extended to the…
