Probably, but choosing src_datasource is the unanswered part...<br>
<br>
ie: <br>
is there a possibility where you can specify columns for eastings
& northings, and not just height?<br>
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?<br>
<br>
Thanks for the pointer though, Kyle.<br>
<br>

Zoltan<br>

Perhaps the utility gdal_grid would suit your needs, see:<br>

Hi,<br>
I have an ASCII file of DEM points that need to be converted
into AAIG format, so I'm hoping gdal (_translate?) will do the
trick<br>
I do not want to rely on the fact that my DEM is column/row
ordered, nor that it is "exactly" 2m spaced.<br>
<br>
Is there some free-format ASCII that gdal can read, or does
anyone know which of the formats read by GDAL won't need to be
"ordered" or "exact".<br>
I'm hoping GDAL will take the pain out of ordering my DEM, and
creating NODATA for missing cell values.<br>
<br>
My file looks like this: (Easting, Northing, height, type)<br>
