Surface Subsidence

[ABraun]

No, you add coherence threshold in the valid pixel expression of the displacement to mask low coherence values.

I explained it in the post above. Just entering the coherence is not a valid logical expression. In this field (valid pixel expression) you define at which locations your result is usable. As coherence is a measure for quality of the interferometric product you only want those pixels at a location where the coherence is larger than a threshold, let’s say 0.4. Thus, just putting the coherence there is pointless because the expression is lacking a condition. Enter this instead: coh_23Nov2012_08…
