BUG: Missing swaths for multiswaths Cosmo-SkyMed SCS data

[remi-braun]

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

➡️ 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...

One more reason to quit SNAP! #2

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

HI Number of swaths: 1

S2 Number of swaths: 1

CSG data in ScanSAR are also affected, but not in ping-pong...

ScanSAR number of swaths : 4

Pïng-pong number of swaths : 1

✅ 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.
