If you are not against the .tlm sidecar idea in GDAL/OpenJPEG, that's
good enough for me for now, and it might allow further discussions
with ESA.
Well, you should tell them I'm actively *against* the sidecar idea to
motivate them doing the proper thing, otherwise they'll have little

Yes, enabling TLM generation for future products would already be an
important first step, and we have asked ESA about this recently.
Given that the full archive of Sentinel-2 was reprocessed recently
(Collection-1), we can assume that we won't get a full reprocessing before
a few years, which is w
Hi,
Someone should just tell the team at ESA (are you reading us ESA by the
way?) in charge of producing those JPEG2000 files to turn on the Kakadu
switch to generate TLM markers. A 5 minute change on their side, ok
maybe 1 hour to update unit tests.
What you suggest about sidecar .tlm sidec
Dear GDAL maintainers,
Thank you for the release of OpenJPEG 2.5.3, with the support of TLM
markers!
Following up on [1], Sentinel-2 JP2 files currently do not have TLM
markers. However, it is theoretically possible to generate an external
index file for each JP2 raster, and the index could be for
