Hello everybody! I am studying deformation analysis on SNAP. My topic is monitorıng of surface deformation with InSAR method. so, the analysis is related to interferometry. I’ll use Sentinel1B SLC datas. But, I don’know
generally, coregistration is the first step. But in case of Sentinel-1 data you better use the TOPS coregistration because it lets you chose the swath and also the number of bursts in order to only work on a smaller part of the large scene. Afterwards you create an interferogram and then you remove the stripes with TOPS Deburst.
The interferograms, histogram and colour legend belong to proceses are above.
*But I don’t know how can I interpret these images?
*Is there anything else necessary to interpret?
*Where should I start?
I would be really glad if you help. Thanking you in advance. =)
please have a look at this topic where we discussed about the information content of interferograms. The coloured patterns you can see are also called fringes. In the mentioned topic you will find some explanations on fringes and external links to valuable resources.
I use Sentinel Toolboxes 64bit version 5.0 (with Sentinel Toolboxes only) and SNAP 5.0 x64 with Ubuntu 16.04.
I follow the tutorial, the registration results are good:
two images overlap almost completely
