this is a known problem and was fixed with the last patch. Please make sure you have installed the latest update (Menu > Help > Search for Updates)
have you also tried the TOPS Coregistration instead?
yes I have
i had tried wih all coregistrations.
please help me
i have downloaded image sentinel othe but it error again
I don’t have a solution, sorry.
Can you please provide the exact names of the two products you are using?
i use thease images
S1A_IW_SLC__1SSV_20150421T122150_20150421T122220_005582_007243_5FC5
S1A_IW_SLC__1SSV_20150503T122143_20150503T122211_005757_007649_F885
did you consider that these scenes are shifted along-track?
That means, sub-swath 5 in image 1 (for example) covers a different area than sub-swath 5 in image 2.
The overlapping sub-swaths have different numbers. 1-6 in the first, and 4-9 in the second, for instance.
Could be a reason why the coregistration leaves an empty product.
I specify IW 2 in both images
IW considers the sub-swath, but you can also select the bursts (demonstrated here). If these do not match (cover the same area), the result will be empty.
so did you select all bursts for both scenes or only a few?
frist image sub-swaths 2 brusrt 1
second image sub-swaths 2 brusrt 4
is it OK?
alright, should be correct then. Please try again and select SRTM 1ArcSec as an input in the Back-Geocoding
@khalill Did you try to process the whole IW2? I’m not sure bursts you select overlap. It could be quite unlikely the bursts you point to overlap. I hope you have disk space to process the whole subswath.
good idea, maby its worth extending to the full subswatch IW2
what i do
please help me
images have overlay togather
