How to Merge two mask bands?

[ABraun]

personally not, but some of it is explained here:

Snappy: Collocate, set 'masterProduct'

Similar to the parameters you can create a map for the source products and then call GPF sourceProducts = HashMap() sourceProducts.put("master", mProduct) sourceProducts.put("slave", sProduct) GPF.createProduct('Collocate', parameters, sourceProducts)

sorry for the formatting in the source.
