dem for Australia

[George Taylor]

Simon,

Thanks for the information on the dem.  I was hoping
to receive a reply from an Australian source for the
best information available.

Since my original post, I found another 5' worldwide dem with bathymetry.
It is produced by the National Geophysical Data Center in Boulder,
CO, USA.  The name of the model is "TerrainBase" and is a compilation of
many models.  The Australian portion is from the Hutchinson model.
This dem fixes many of the errors in ETOPO5.
