By the way, I don’t see a way to tag the accuracy or confidence level for a
measurement. Seems like we ought to have something like *:confidence=*, similar
to the *:lanes tagging so we could, for example tag the width of a road as:
width=18’0"
width:confidence=2’0"
I’m not sure we really need this, road width will have small variations anyway.
Road widths can vary. But a general method of tagging uncertainty could be
useful for other things. It gives a way of indicating that the location of some
items has been surveyed with professional equipment and techniques and is
accurate to, say, a centimeter.
The variation of the road width should be included in the uncertainty.
