[osg-users] Convert .earth file to .osg format

[Chris Hanson]

Also, to add to that, osgdem relies heavily on GDAL to ingest raster data.
GDAL has several tricks for combining multiple files or directories and
referencing them as one dataset. For example:

https://gdal.org/gdal_vrttut.html

I don't recall ever using that technique with VPB, but in theory it could
be helpful.
