About number of unclosed loops (n_loop_err)

[HamedAmirkhani1378]

Hello My question may be related to the basic topics of InSAR, but I ask them.

1.What are the reasons for high number of unclosed loops in some areas or pixels? Vegetation? 2.Can I skip masking these pixels and trust them?

I have attached an aerial image of the study area. Also I processed with nlook=10.

It could be

• decorrelation (maybe caused by vegetation)
• unwrapping error

2.Can I skip masking these pixels and trust them?

You can skip, but of course the reliability of these pixels is lower than the others.
