I have a recurring problem with the coherence images that I calculate from SLC files, which is that I often obtain black empty images when I open the .DIM of these images, but not when I open the .HDR (in the .DATA folder created with the .DIM)
For example, here I opened the .DIM :
And here is the .HDR :
I don’t understand why it does that for some of my images but not for all. Is there a difference between the two format ?
Also I would like to use these images with the time series tool for extracting curve values from polygone, which worked with GRD, but doesn’t with both .DIM and .HDR
Thank you in advance
