S1 TOPSAR Interferometry on S1TBX - Further improving interferogram coherence

[ABraun]

create stack is for geocoded rasters, coregistration is for SAR products in slant range geometry

Co-registration of Various Products from Different Satellites

let me try to summarize it: if you have only two datasets and both are well geocoded, collocation is sufficient. if you deal with multiple rasters and all are well geocoded, you can use create stack. if you deal with data acquired from different sources or angles or you have terrain-induced distortions (often the case for radar data) you need coregistration to match the rasters precisely at the sub-pixel level. This is also required for interferometric analyses Please, anyone feel free to com…
