Hi,

There have been improvements in GDAL 3.4.0 (*) regarding SLC products in the SAFE/Sentinel 1 driver. I can see that it seems to work fine on a S1A_IW_SLC__xxxx dataset. I don't have EW SLC products at hand

Hi list,

GDAL Sentinel-1 driver question:
I know that GDAL Sentinel-1 driver works well on GRD (detected).
What about SLC?

Level-1 IW SLC product contains one image per sub-swath, per polarisation channel, for a total of three or six images (3 tiff for HH, or 6 tiff for HH/HV dual-band)
The EW SLC products contain one image per sub-swath, per polarisation channel, for a total of five or ten images.

Thank you.
