I am definitely not the expert who had addressed that for previous
protocols, but i remember there was always a heated discussion (3825
comes to my mind).
First, there's a difference between "uncertainty" and "object dimension"
(uncertainty is how "unsure" the measurement is, while what you describe
is more "what is the approx. Size of the location to be represented).
Then, what is the "dimension" of those values? Is is a circle, or a
sphere? In "natural" space, or in the "projected" space (lat/lon circle,
which would definitely not give a circle in "real world"?) What is the
dimension (meters, inches, degrees?).
If you want, we can set up a quick chat here in Stockholm about it - and
i would love to have someone who was involved in other "uncertainty"
discussions joining...
