Which is the higher priority, consistency or accuracy? Is it better to
have an internally consistent map, where everything is topologically
correct but possibly a little displaced by a uniform vector, or is it
better to have some of the objects positioned with high accuracy,
despite the apparent

What about when an object (perhaps a road or a boundary) is replaced by
