It's not just centreline data - there's also cross-section data,
and you do get "*export" information in the 3d file - check for
img_SFLAG_EXPORTED in the "flags" member when you've just read an
img_LABEL.

The *team command is not currently carried through though.  It
exists as a command so that datasets can put this information in
a form where a future version can start to handle it (which seems
more helpful than users having to put the data in comments and then
update a lot of data once support is added).

You can view exported points in aven using the "View->Highlight Exported
Points" menu item - they then appear as small blue blobs.
