Unexpected Phase Jump Results

sweets_config.yaml

Hi, @scottstanie
I often tested sweets for quick results in deformation analysis. I think step 1 and 2 works well. But when I finished the whole process ( with step 3) and exported results to QGIS, I showed many phase jump problems in plotting timeseries. Mostly I used stride 1 1, snaphu, snaphu cost defo, tile overlap 100 100, etc. Actually,  I tried to update the dolphin version to the latest one, but I got the same results. I looked disp-s1 .yml files to fix the problem but it didn’t work for me. Any advise?

hmm it's hard to tell what the underlying area is for these time series. Are you plotting it over some kind of agricultural field/ vegetated area (where unwrapping errors are likely)?
I do agree that the velocity looks pretty splotchy and full of unwrap errors. Maybe you could try with something like

  half_window:
    - 14
    - 7

(and, if you want, to make the output 20 x 20 meter to run faster)

- strides:
  - x: 4
  - y: 2
