Dear all,

I’m new in SNAP, and I tried to process the co-seismic surface deformation of an earthquake in Taiwan on 2016/02/06 by sentinel-1A IW ascending images (20160202 and 20160214).

I have got the interferogram and the coherence map, but there is something wrong after unwrapping by SNAPHU.

I don’t know why there appeared value in the sea area. And the unwrapping result seems wrong. Could anyone help me to deal with this problem or give me some hints? Thank you!

The parameters I used for snaphu export is as follow:

Statistical-cost mode: DEFO

Initial method: MCF

Number of tile rows: 10

Number of tile columns: 10

Number of processors: 4

Row overlap: 0

Column overlap: 0

Tile cost threshold: 500
