[gdal-dev] No Spatial Reference System from UTM Ozi .map file

[Nik Sands]

Thanks for the replies so far.  Unfortunately, adding a 3rd calibration point to the .map file has not helped.  Of course I'm assuming that the added calibration point is valid (eg, I tried the one suggested below, which looks like it should be OK).

Does anybody have any other suggestions as to why this .map file cannot be interpreted correctly by GDAL?

Is it a bug, or an incomplete .map parsing implementation, or am I doing something wrong?

Cheers,
Nik.
