[gdal-dev] ASCII file to AAIG format

[Zoltan Szecsei]

Probably, but choosing src_datasource is the unanswered part...

ie:
is there a possibility where you can specify columns for eastings & 
northings, and not just height?
or does anyone know of an srs_datasource that I can restructure my file 
to, that does not make me do the row/column ordering, nor the check for 
empty cells?

Thanks for the pointer though, Kyle.

Regards,
Zoltan
