It's very difficult to draw such long lines in P2 without crashing the browser. Looks more like a mistaken import from an external file to me.

Yes, I don't use version numbers on P2 because I can never remember how all that git tagging stuff works. :)

@Jojo4u: Potlatch 2 was most recently updated in 2014, not 2011.

Welcome to OSM! What were you trying to do with this edit? way/345001740 doesn't look like a new feature or anything else that's on the ground.

Good spot! Fixed.

Has this been discussed on the mailing lists, and documented on a 'Mechanical Edits' wiki page, as per osm.wiki/Automated_Edits_code_of_conduct ?

A lot of the Montgomery towpath has been upgraded to shared-use cycleway standard recently. Off the top of my head I can't recall whether this bit has been done yet, but if it has then highway=cycleway is entirely appropriate and is the way that similar upgraded towpaths are tagged across the network.

Personally I'd love Sustrans to reroute NCN 81 onto the towpath south of Pool Quay and then across Maginnis Bridge, which would cut out the climb of the Long Mountain. :)

Please don't remove them! OSM takes rights of way very seriously, more than any other mapping organisation other than the Ordnance Survey.

At the same time we're a global project, so we can't show every single peculiarity of every single country in this map view. The main view on openstreetmap.org itself has to be a global "lowest common denominator". But that's why OSM encourages others to take our data and make their own specialised maps from it - for walking, cycling and a thousand other uses.

robert was being a grump about the manner in which you added the tracks. But that's the fault of the site making the "ideal way" non-obvious to a beginner, not any fault of yours, and he was out of order in not recognising that.

Despite the old grump above (we love him really), great to have you on board. :)

In general if you're changing long-standing data in matters of interpretation, rather than unarguable fact, you should think about consulting others first. Peckham has been tagged for over five years as a town in OSM. It's unlikely that you have noticed something so significant that London OSMers (the most active OSM community in the UK) have missed for all this time.

FWIW, Tom's mailing list posting wasn't referring to you as a "self-appointed wiki editor" - I think you've misread it.
