Hi,

Just ran the command. You are correct, the files are not the same, all the 
layers have been stripped out. I am using WindowsXP, Visual Studio 2008.
I will do a fresh checkout and build when I get home tonight (if the kids allow 
it : )  as I cant access an external SVN server from the work network. It seems 
odd that the different platforms would result in this behavior so its worth a 
tripple check.

Hi Brad,

I just run the test along the lines of yours:

vpbmaster --bluemarble-west -t
../BlueMarble/land_shallow_topo_west.tif -o out/test.ive

And it run to completion without any problems.  The generated
build_master.source is included below, and looks pretty similar to
yours.

Could you try doing:

osgdem -s build_master.source --so test.source

This will load and then re-save the terrain description, the above
test results in test.source that is identical to build_master.source.
My guess is that on your system it won't be.

What OS/compilers are you using?  I'm using Kubuntu 9.04 and gcc 4.3.3.

Robert.
