Handling sentinel data in python ( working with snappy)

[marpet]

There are two problems I currently see.
The subet operator does not have the parameter outputImageScaleInDb. You should remove this one.
Instead you should add as parameter which bands you would like to have in your target product.

parameters.put('sourceBands', 'B7')

The call to GPF.createProduct() should get the source product as last parameter and not a band.

target_1 = GPF.createProduct("Subset", parameters, product)

This way it might work.

Actually you don’t even need to use Python for this, of course you can if you like, but it can also be achieved by writing a graph XML file.
If published an example here:

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…
