	gdal_translate -co "Resample=Bilinear" ...

The options are 'Nearest, Bilinear, Cubic, CubicSpline' when the output 
is USGS-DEM/CDED. The docs say "Only has an effect when particular 
products like CDED50K are being produced. Defaults to Bilinear." But 
doesn't go on to say what the other formats might use the same option.

Note: don't use Cubic or CubicSpline with images possessing nodata as 
the nodata is interpolated (Bug:793)
