Easier, well at least faster, then that

The fgCurrentElev() routine takes
sgdVec3 abs_view_pos as its first argument

which normally is
globals->get_current_view()->get_abs_view_pos()

which I believe is still the AP CG
so I believe that you could just add the offset for each query point to 
the abs_view_pos vector

see tilemgr::update() for whee this is called currently
