I'm experimenting on the CIB issue only to have more hints of the exact
of the problem.
I try to comment the block of code in nitfimage.c at line 3046 that reports
the error on the location table corruption and that consequently resets the
location table data structure :
CPLError( CE_Warning, CPLE_AppDefined,
"Ignoring NITF RPF Location table since it seems to be corrupt."
CPLFree( psImage->pasLocations );
psImage->pasLocations = NULL;
psImage->nLocCount = 0;
After this modification I am able to display the map but with evident
visualization errors likely due to bad decompression.
Perhaps this can be a consequence of some form of bad reading
of the QV LUT to decompress the image?
Last thing...As I said in my first post, OGDI have no problems to manage
these datasets. I tried to check the OGDI source code but I'm not a NITF
specialist and so I was not able to understand what are the actions that
OGDI do well respect to GDAL.
