There is Git Large File Storage (Git LFS), which has a limit of 2GB.
Yes, but there are billing / bandwidth implications. I remember we had
it enabled, but CI cloning typically exhausted the allowed free bandwidth.
Javier, maybe you can try using gdal_translate -scale X X X X -ot UInt16
-co COMPRESS=DEFLATE -co TILED=YES -co PREDICTOR=2 with the appropriate
scaling values ?
Or gdal_translate -co DISCARD_LSB=X -co COMPRESS=DEFLATE -co TILED=YES
-co PREDICTOR=3 to nullify least signifcant bits of the mantissa.

Hi
I am playing with the new American geoid model SGEOID2022
After compressing with this command (can I do it better?)
gdal_translate sgeoid2022.tif sgcomp.tif -co COMPRESS=DEFLATE -co
TILED=YES -co PREDICTOR=3
I get a 110 MB file (and it is only one band. No velocities).
GitHub has a limit of 100MB:

Just to let you know.
Cheers,
