Hi every one,
i need to Perform coherent change detection(CCD) with sentinel 1 (SLC) .
What is the ideal steps to do that .
Hi every one,
compute coherence for your image pairs as described here: Sentinel-1 TOPS interferometry
calculate coherence for different image pairs and compare the change in coherence.
Thanks a lot
I just would like to clarify about CCD. Coherent Change Detection method is done by calculating coherence between two image pairs and then is compared by Change Operator and the result of this process is Coherente Change Detection ?
So if I want to perform CCD I should calculate Coherence between e.g. SLC image from of 1st of June and 7th June and then between 7th June and 14th June and then compare the Coherence bands using Change Detection ?.
I just cannot find any tutorial with all processing steps for Coherent Change Detection using SNAP. I went through SNAP Forum, I was looking for this information in presentations from ESA Summer/Land/etc. schools, in SNAP website, Alaska university radar website and I have read many articles but I just did not find any tutorial with processing steps for Sentinel 1 SLC Coherent Change Detection or I was absolutely blind. Do you have some more information or some tutorial ?
Thank you for your help.
404 not found the tutorial Mr @ABraun and i have a question about the ccd formula
the post is from 2018, I updated the link. You find the new tutorial here: Sentinel-1 TOPS interferometry
