SNAPHU Unwrapping question

[sentinelgyb]

Hi, everyone.
I have been working with images of Sentinel 1A IW SLC and I have done coresgistration, interferogram formation, deburst , topographic phase removal and phase filtering. Now i will do the step of phase unwrapping. Anyone can tell me which menu should i use firstly? SNAPHU IMPORT or SNAPHU EXPORT？ If SNAPHU IMPORT menu, which product should i select for 1-Read-Phase and 2-Read-Unwrapped-Phase,respectively? Now I have 7 products in the left table of contents.

Thanks.

Please take a look at this topic

Import Unwrapped result back into SNAP for terrain correction

have you run snaphu correctly? First, you need an unwrapped product (one *.img and one *hdr image)? Second, a reference image (interferogram before unwrapping) in DIMAP format must be opened in SNAP. If both are present, you can run the SNAPHU import as described: 1-Read-Phase (this is the reference file, usually the one before the unwrapping) [image] 2-Read-Unwrapped-Phase (here you chose the hdr file of the unwrapped phase created by snaphu) [image]
