Add support for display of coherence or correlation data #60

Open EJFielding opened 3 months ago

EJFielding commented 3 months ago

The InSAR coherence or correlation is an important additional type of data. For ISCE2 output files .cor files have the same file format as .unw files with an amplitude image interleaved with a correlation image. I was able to get an ISCE2 .cor file to display by selecting the "unw" option in qed.

For NISAR-format outputs, the coherence or correlation is a layer in the GUNW h5 files, so it would be great to add support for displaying that layer of the GUNWs. I see that Paul already asked for this enhancement in #47.

The coherence or correlation should be in the range of 0.0 to 1.0.

Hi @EJFielding, regarding the isce2 files, sounds like the current qed can display .cor, .unw, .int files? I am just curious to try qed on isce2. But since qed is only web-based notebook, I would need to upload my isce2 files onto the on-demand system in order to display? Thank you.

Hi @yuankailiu, it is possible to run qed locally on your computer, but I have not tried it. @aivazis told me that he runs it on his Mac all the time for debugging and development.
