I'm not Pierre-Luc, but GPS frequently has an order of magnitude more
vertical error than horizontal error.  Trying to squeeze this situation
into a single error number requires you to overstate one or understate the
other.

Of course, there's no limit to perfectionism, and I'm not aware of any
application that uses the error field at all.  The perils of design...
