Hi guys,

(which was bought by TomTom) improve their data. The article itself is
very educational, but the accompanying images are quite informative in

This goes to show that even though a GPS may have errors, given enough
data, the errors are averaged out and we can get real positional
accuracy. So keep on uploading those (cleaned-up please) GPX traces!
