Ah sorry about that. I thought OGR formats and GDAL Raster Formats were
the same thing. Thank you.

Hi Norman,
Yes this sounds like it should work. I'll try it when I get a chance. If I
made a geotiff with no navigation(WKT) and had X,Y,Z as individual bands
would that work? How do I tell gdal_grid which dimension or band is X,
which is Y, and which is Z? Thanks.
Could you please CC me in any replies, I get the digest and it's easier to
reply if I get the original email.

Seems to me this is a point not a raster process you are looking for
e.g. How do I make a surface from a bunch of discrete points ?
So instead of having 3 bands of raster you want a stream of XYZ triplets
you can then submit these to gdal_grid or other tools that work with
discrete
data
pseudo python assuming you have read your files into numpy arrays
XYZ = array( zip( bandX.flatten(), bandY.flatten(), bandZ.flatten() ) )
convert XYZ to any OGR format
call gdal_grid
