I think the problem is that I'm trying to do the conversion in memory, not on disk. If I've read your latest reply correctly, I'd convert to JPEG2000 on disk and then copy to S3? Can I do the conversi

Would you say it's worth raising an issue on GDAL then? I'm also not familiar with the Python GDAL bindings, Rasterio is my window in that haha.

As with Guillaume's answer, it's a Sentinel 2 band and has no side-car file, when I write straight to a file, the georeferencing is maintained.

I tried this with GDAL 2.4.2 and GDAL 3.0 too If anyone can point me to where I might look further to diagnose this, I can create an issue with some useful info, whether that's in Rasterio/GDAL :)

Revised: Don't require the seek call: s3_r = boto3.resource('s3') profile = source_image.profile.copy() with rasterio.io.MemoryFile() as stack: with stack.open(**profile) as stack_out: stack_out.write

On further inspection, when I switched to saving my outputs as GeoTIFF, the resultant images are both geo-coded fine (Disk vs. In Memory to S3). I'm guessing something is going wrong when .jp2 is invo

Hi there, I'm currently re-writing a process that was stacking .jp2 bands into one image and writing the resultant stack to disk. I'm moving this up to AWS so want to use MemoryFile's instead. My code
