Hi Even,
Thanks for the help.
I was wondering if I could just get this byte range from the file, and save
it as jpeg2000 (with .j2c or something like that) and have a valid jpeg2000?
My goal is to be able to extract the jpeg2000 without using gdal_translate
in order to save time and resources (cpu,

Yes! That is it. It explains so much. Thanks for figuring this out. I learned
something important today.

That's what I originally tried and it didn't work, but it does now. Maybe I
made a typo.
Seems all right,

Well, a new install of gdal from conda-forge and now it works fine. Sorry for
the noise.

I'm building gdal from conda-forge. I do compile in two plugins (mrsid and oci)
but I wouldn't that it would affect things.

Michael,
I've also just tried with 3.7.0 from conda-forge and this works fine for me:
I've just slightly modified your script to output more info:
from osgeo import ogr, gdal
ds = gdal.OpenEx('{ "type": "Polygon", "coordinates": [ [ [
179.828821134787177, 66.686572724877635 ], [ -179.71878684
I assume I am doing something incorrect here but I am taking an incoming
geojson feature and attempting to split it on the dateline:
Using gdal 3.7.0 from conda-forge
ds = gdal.OpenEx('{ "type": "Polygon", "coordinates": [ [ [

Hi,
if you open such an image with debug traces (CPL_DEBUG=ON), you'll see
something like
GDAL: GDALOpen(/vsisubfile/907_565,byte.ntf, this=) succeeds as
JP2OpenJPEG
which means that the JPEG2000 file starts at byte 907 with a length of
565 bytes.
Programatically from C/C++ , you cou
Hi Haddad/Rob;
I tried conversion of DWG to DXF and then ran command; but I am getting
errors I have mentioned in the shared document(on Drive); I have shared the
DXF file too.

Hi Eric,
Yes, you can transcode them on the fly with a server like
https://github.com/developmentseed/titiler. I haven't used that one, but wrote
a prototype of something like that in the past.
You might want to have the original in EPSG:3857, though, to avoid the need to
reproject the tiles w
I don't know how to do that without significant code. What you can do, given the right gdal build, is to extract the image and recompress it as JPEG 2000. That would have the advantage of working with just about any NITF compression method, not just C8/M8. Obviously that does involve more CPU and p
