Ollie,
There's probably nothing wrong with your dataset. The error comes from the
part of the driver that tries to mosaic all the NITF tiles from the CIB
exchange. The error issued by the RPFTOC driver is an assertion that checks
that the theoretical placement of the tile into the mosaic given by the
A.TOC file is consistant with the georeferencing of the NITF tile itself.
The assertion would indicate that the longitude of the north west corner of
the tile wouldn't match the one deduced from the A.TOC. Maybe the test is a
bit too strict on the precision. I don't know. I've been able to test the
driver on many CADRG datasets, but no CIB until now. What would help to
understand is sending the output of gdalinfo on the .\NI425J2\01LGBN2B.I42
tile to get its georeferencing (gdalinfo on other random tiles could help
also to see/confirm if it's limited on a single tile or a general
phenomenon) and joining the A.TOC file which is just an index and contains
no imagery. You could create a Trac ticket (http://trac.osgeo.org/gdal/) for
that. (I won't be able to look at this before two weeks).
Best regards,
Even

Can you make .\NI425J2\01LGBN2B.I42 available for inspection? I imagine

will need to comment on the particulars of the RPFTOC driver - I see this
assertion is coming from it, not the NITF driver.

Hi Frank,
Unfortunately I think that would be unlikely as it's a limited
distribution
military data set. I know this doesn't help a great deal!
Attacking this from a different angle I am now using gdal_translate to
translate each of the 1073 tiles (which are in NITF format) to GeoTiffs
and
then mosaic into a single image. This will run overnight based on the
current rate but so far has produced 1073 previewable GeoTiffs (which at a
random sampling process all seem to contain some data) and is working
through the mosaic operation. I'll confirm the results in the morning but
this may help narrow down where the problem area may be - or not (I'm not
familiar enough with the GDAL code to know whether this helps)
Thanks
Ollie
