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

[Nik Sands]

Is that limitation actually built into GDAL?

Because 2-point .map files are not uncommon, and so long as the two points are both different in both axes, then there should be no reason why a 3rd point in required (especially in UTM).

Cheers,
Nik.
