Hi all,
I ran gdalinfo (both gdal 1.5.2 and gdal 1.6.0) on a nitf image and got
the following message:
gdalinfo caf_08mar12.ntf
ERROR 4: ‘J2K_SUBFILE:3935,115450995,caf_08mar12.ntf’ does not exist in
the file system, and is not recognised as a supported dataset name.
ERROR 1: Unable to open JPEG2000 image within NITF file.
Is the JP2KAK driver available?
gdalinfo failed – unable to open ‘caf_08mar12.ntf’.
What is the meaning of the message (especially ERROR 4)? Thank you in
advance for taking time to answer.
Mo,
ERROR 4 maps to "CPLE_OpenFailed" as defined in gdal/port/cpl_error.h.
The error basically means that your NITF file contains a JPEG2000 compressed
image so the NITF driver attempted to open that as a subdataset using the
specal J2K_SUBFILE mechanism but this failed. Mostly likely it failed
because you do not have JPEG2000 support built into your GDAL library.
Best regards,
