I am performing Differential Interferometry to study deformation on glacier surface. Unfortunately my glacier falls right at the edges of IW1 and IW2 of an IW SLC product.
The steps that I follow until SNAPHU unwrapping are
Open Product > TOPS Coregistration > Interferogram Generation (Including Topo Phase Removal) > S1 TOPS Deburts > Goldstein Phase Filteration > Subset > SNAPHU Export.
Could someone suggest me which would be the most appropriate stage for IW1 & IW2 merging using TOPS Merge Module? From other posts on the forum I understand I will have to individually processes each subswath for Diff. Interferogram generation and then merge it later.
