Java Heap Space Error during the creation of a GeoTIFF that preserve both backscattering and incidence angle

Hi,

what I wrote here in the post should help you.

Closing/destroying files after reading/writing?

it should be no problem to write a function which returns a product. For instance in this example a function is written which returns a band. Not a big difference compared to a Product from a API point of view. You can call product.dispose(). This will release all for this product allocated resource. The product will not be usable aftwards. To release memory explicitly you can call the Java Garbage Collection. System = jpy.get_type('java.lang.System') System.gc()

Dispose products you don’t need anymore, and call the Garbage Collector by System.gc()
This cleans at least the Java side.
But it also depends on how you are using the data on the Python side.
As a general comment - I don’t know your code or what you are doing Python - it helps to reduce memory if you process the data in chunks and not the whole scene at once.
