I agree that an important question is what are the use cases. For example,
if the use is to find out how far from location L the annotation was
created, one must perhaps know the accuracy of L and of the creation
location.  Other provenance use cases may require 2d representation.  For
example if you annotate a feature of a picture of the Eiffel tower
and give a point   creation location near the  tower, i might respond that
you cannot see that feature from that location.
