Disconnected patchs in the output velocity map

[SadeghiZ]

Hi @scottstanie ,

I've just started to test working with sweets/dolphin, I processed S1 data set over a man-made area in London,UK, please find attached the config.yaml file which I created, I can see some disconnected patches in the velocity output file, I also checked the interferogrmas.unw.conncomp files, and the disconnection is clear there as well while the conncomp_intersection file looks connected, I 've seen the discussion #718 which you mentioned about activating interpolation during unwrapping and even I increased the default of max_radius for interpolation to 101 pixel (based on the width of the river), but still same issue is there. Could you advise how I can solve this issue?

Another question is, we can see in the velocity map, basically there are noisy pixels in low coherent areas, which files can be used to filter out unreliable pixels? I can see that temporal_cohrence and phase similarity are available in the timeseries folder for EACH MINI STACK, are they the only products that we can use by thresholding to filter out the noisy pixels, is there any pipeline in Sweets or Dolphin to run this step?
