Hi,

Looking at the accuracy attribute[1] in the Geolocation spec which
reads:

"The accuracy attribute denotes the accuracy level of the latitude and
longitude coordinates and is specified in meters. [...] The accuracy and
altitudeAccuracy values returned by an implementation should correspond
to a 95% confidence level."

I assume this means that the user agent is actually positioned within a
circle with radius equal to the accuracy in meters. Is this a correct
interpretation?

Thanks,

--tobie
