Thank you for pointing out that the lower levels are more up to date. I have got into the habit of using zoom level 21 in London because of the better alignment.

First of all you would probably be better off asking this question on the OSM Help Centre or a Japan-related Contact channel.

Whether or not it is better to use route relations for road numbers is a question of local conditions such as whether roads are signed with two numbers equally.

There is generally no need to repeat the numbers of roads in their names.

Tom: I was thinking of doing just that as soon as ODBL compliance issues have been sorted out.

I have been treating the work of the main non-accepting mapper in the area as possible trap mapping and making a clean map. For instance I got no response when I asked why he had given a road a number I could not find on other sources and some cycle routes he put on the map appear to have been invented by a club he belongs to.

Anyone free on 10th or 11th February?

To make this clear, this post is about landuse polygons that extend beyond the edge of the land they represent to the middle of the road (or the middle of the carriageway), where the road has been mapped as a single line.

What do you mean by ‘origin of the trees’?

You might as well let the Vale of Glamorgan journey planner know.

Most of the existing map of Bermuda has been added by outsiders tracing aerial photographs. Finishing it off takes locals like you. Don’t forget you can ask the rest of us for help.

Is there ever any point in putting the road number in the name= field? We always leave name= blank on motorways that haven’t got proper names in Britain.

You don’t have to know much Turkish to recognise spam when you see it.

don’t know about anywhere else but there are quite often meetings scattered round the UK as well as the regular events in London and Birmingham, and they don’t show up on the map.

Practice make perfect. You’ll find things easier as you put more stuff in.

Are there any other maps that are up to date?

Some corners of the world are always going to be a bit difficult.

Le cadastre français est-il utile?

It would be worthwhile asking Keep Right or one of the other validators to identify nodes common to roads and power lines and other aftereffects of excessive node merging.

The code of conduct was written in response to slap-happy imports in the USA, especially TIGER, much of wich deserves little respect. Repairing the broken topology form these imports justifies the odd bit of collateral damage, although you should still fix it when you find it.

A potential talking point: How many building outlines should we import from StreetView?

If you find building outlines iin Yahoo hard to follow you can try StreetView, which isn’t really any worse. Of course there’s much better aerial photography if you’re mapping Surrey…
