Ray, I need to import LEVs and export as TGs on a 4 x 4 tile set (@5K

a script for me? :)
Well, Lev scripts don't extend to any file I/O, so you'd have to roll a
plug-in or use the Python bindings for GDAL (since both the Leveller and
Terragen drivers are now from GDAL). Even just setting up a batch file
and calling GDAL's warp utility should do it. I don't know if the
current official GDAL includes the latest Lev/TG drivers though from
their site, but if not, I have the sources here if you don't want to
grab them from the gdal 1.5 branch.
Thanks,

btw, I got a crash on trying to load a 10K LEV (output from Global
Mapper). do you want any more details or should we file it under 32 bit,
blah blah. There was only a Microsoft dialog anyway, that's about it.
If you mean it's 10000 x 10000 pixels, and you have enough RAM, you may
need to enable the 3-gig switch (/largeaddressaware or something like
that) for the leveller.exe file.
