It seems that ESA SNAP only orthorectifies one swath of CSK SCS data:

2023-02-20_10h00_49

➡️ When opening the .h5 file in SNAP, only one swath is seen, so this is a SNAP issue.

WR number of swaths: 4

It seems OTB and other softs are failing too...

This seems to only affect the Wide Region product type, and doesn't affect neither the HImage nor the Enhanced Spotlight type....

✅ A workaround has been found:

  • Split the .h5 file into single-swaths (all renamed S01)
  • Pass to SNAP those single-swath cosmo products
  • Apply the classic GPT graph
  • Merge the results

Multiswath needs only a workaround for SCS data, not GRDH!

💡 In fact, multi-swath GRDH data are working fine with SNAP.
