Duplicate tiles in InterferogramOp

Microwave Toolbox
#1

Dear SNAP forum,

I have a new question / bug that is related to the interferogramOp. I have a big stack (~70 images) with (oversampled) images. When I want to create interferograms, I ran into the problem that there are duplicate tiles and therefore the whole operation is slowed down significantly. When I try it with a subset of only 5 images, there are no duplicate tiles.

I have solved the problem by a workaround now (checking if the rectangle has already been processed), but I suspect that the problem is maybe related to the framework.

I have used RSAT2 and Envisat data for this.

Regards,

Same problem here. The computeTileStack() method of InterferogramOp gets called more than once for the same tile. I’m using the master branch (as is) at the time of writing.
