I am bringing up this post with another back geocoding error.
I am processing long time series of coherence images and I have observed a bad scenario. I am coregistering S1A/S1B data from orbit 131, common burst from slices 19 and 20 IW1.
Half of back geocoded products are invalid. As I see, if data from S1A is master, back geocoded product contains its data, but layers from slave product are empty.
Maybe someone has experienced this issue and can suggest some good solution?
Also, is there any difference which image should be used as master (newest or oldest) for coherence estimation? As far as I understand, coherence value doesn’t change depending on master/slave temporal order, right?
