I don't have a ready to consume tutorial, but your first goal is to use
osgEarth to build a dataset by merging all your data together.
The second is to feed that to VPB.
Let me think on the matter a bit.

Basically, osgEarth is really good at doing fancy layering of data sources.
VPB is a little trickier, but can do most of the same things (for elevation
and raster data anyway).
I was thinking it might be easier to use osgEarth to turn your multiple
layers of GeoTIFF images into a single elevation
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 co

It's a single-precision 32-bit floating point TIFF. Values could be
anywhere from -FLT_MAX to FLT_MAX.
I'm just making sure it doesn't have weird values like sea level being 0

I really feel like you need to step back a couple of steps and get a
working process.
Like, can you build a dataset with JUST elevation data and just ONE simple
GeoTIFF terrain elevation file? When you have a process that works, you can
work forward, adding complexity and watch for where it breaks
WHen I say build a dataset, I mean, run it through osgdem and produce a
.osg or .osgb and test it.
Start simple, then if you get that working, add complexity until you find
the breaking point, then fix whatever you identify as being the problem.

It sounds like osgdem's idea of 'levels' may not correspond to CDB's, and
increasing the number os osgdem levels may be the right solution.

So, I theorize that you are loading a 2d vector field as a data layer, that
