Hi,
Thanks @nicola.ciapponi for the explanation of the use case. Thanks @stefaan.lippens for digging into this!
Here are two tests I have conducted, more on the technical side.
Question: How to use the result of aggregate_spatial as a threshold in the following processes?
Example: Directly use the result of aggregate_spatial and connect it to the context of apply with a callback gt that will be used for masking.
