Just to go sure: Slice Assembly is not a mandatory task for Coherence estimation. It is only required when you have two images from the same date and track and want to merge them before creating the stack (with two other images). If you only have a pair of images of the same footprint, you don’t need it.
If you want to do 6-day coherence with S1A and S1B, slice assembly is a good option, because unfortunately, the frames of both sensors only partially overlap. The problem is that data sets get so big that SNAP will crash on memory issues, even on relatively well endowed machines (e.g. 16 GB RAM). This is also because the SNAP s1tbx is not very efficient in RAM use overall.
Hello,
I am trying to merge two images from the same date and track before creating a track but I am getting an error message like the one luk123nov has experienced.
How do I resolve the error message Error: [NodeId: Slice Assembly] String index out of range:48 while working with the S-1 Slice Assembly command?
