I can't seem to find any description of it and I don't have a copy of ISO 15444. e.g. ISO/IEC 15444-1:2016 http://www.iso.org/iso/catalogue_detail.htm?csnumber=70018 I see changes like r4958 and r16870. So it's something different? And there is this: {{{#!python def jp2kak_8(): if gdaltest.jp2kak_drv is None: return 'skip' tst = gdaltest.GDALTest('JP2KAK', 'byte.jp2', 1, 50054, options = ['QUALITY=100']) return tst.testCreateCopy(vsimem = 1, new_filename = '/vsimem/jp2kak_8.jpc') }}} In the Jasper docs, I see ""jpc JPEG-2000 Code Stream"" codec. https://github.com/mdadams/jasper/tree/master/doc {{{ One of the two image formats specified in the JPEG-2000 Part-1 standard (i.e., ISO/IEC 15444-1 [8]) is the so called JPEG-2000 code stream format. The JPC codec in JasPer implements this format. }}}",task,closed,normal,,GDAL_Raster,unspecified,normal,invalid,jp2k jpeg2000 jpc,
