Hi David,
I haven't dived into the source code of osgEarth, but I do know that
it utilises osgTerrain, and osgTerrain internally uses double to
locate tiles in their geocentric position (the class that does this is
the osgTerrain::Locator). When the geometry for rendering is
generated on demand
David,
I'll just chime in for the record to echo Robert's correct assessment --
osgEarth uses osgTerrain under the hood, and osgTerrain solves the precision
issue by localizing each tile at each level of detail with a
double-precision matrix.

Hi,
Is OSGEarth suitable to use, as a part of a terrain simulator, together with
objects that needs to be positioned with about cm precision - or will I run
into problems with precision? I found this page about how they handled it in
NASA's World Wind:
