Great work, keep it up! The wider New Cross / Deptford area could do with some work as well.

Great stuff, good luck getting your head around OSM.

I've talked to the London Orchard Project previously about mapping orchards, which they did in the end using Google Maps because OSM was too complicated:
http://thelondonorchardproject.org/current-orchards-map

But I hope one day to change that. They did send me a link to use their data, which is free of copyright problems, if we wanted to import it into OSM.

You may also find this project interesting: http://www.openecomaps.co.uk

Have you contacted them to suggest they use OSM tiles in the map?

Glad to have been an inspiration! I've tried to make parks in my patch of Southwark really beautiful, consistent and useful for park fans like myself. It would be great to get more parks looking like this.

Crikey, the worst that happened to me mapping Reading years ago was walking into a culd-de-sac where a bunch of rough looking young men, one of whom was holding a knife, glared at me. That was Whitley.

I'll send this to a friend who is a councillor - he's in the Park ward, but might be interested.

You'll find the default OSM stylesheet is a bewildering, painstaking work of love!

Try starting your own stylesheet and you'll quickly realise how much copying & pasting you need to get even a half-decent map.

I think you also have to be a bit careful about the amount of post-processing you expect data users to perform, simply because it adds more hurdles for potential data users. Unless of course there are people out there willing to do that post-processing and offering up ready-to-use data.

Well I look forward to your commentary when Gregory publishes his toilet map and we make that a project of the week!

Is it possible to limit it with a bounding box? It might be a fun way to get people to finally tag speed limits in London, for example.

Harry, I love this... can you do it for some other projects of the week? :)

(used judiciously so as to keep it exciting rather than a humdrum regular thing)

Good work! Brings back memories of mapping the Sustrans route 4 down the canal, a lovely route.

How about some mapping parties to check the OS Locator / OSM discrepancies?

There are big chunks of Lambeth, Lewisham, Tower Hamlets, Wandsworth and lots of outer London boroughs that nobody seems to have done much work on. We'd have to travel a bit more but it can make for quite nice bike rides on a summer evening pedalling around checking off a list of ten or fifteen road names.

It would be fantastic to get the whole of Greater London >95% checked.

Thanks for the update Harry, though I very rarely make them it's interesting to read what was discussed.

The buildings are a mix of sources/techniques. The middle section in north Peckham/Walworth was by automatically vectorising, fixing up and merging in OS StreetView data. The north section is a mix of StreetView, Bing aerial imagery and on a few roads ground surveys because the buildings are quite hard to understand from imagery alone. The southern section around south Peckham and East Dulwich is all ground surveys with Bing and StreetView to get good building outlines with full address info. That technique takes absolutely ages but it looks nice and is hopefully useful :)

Personally I'd like to see at least StreetView traced buildings across the whole of London, with improvements using Bing and ground surveys to gradually refine it. As with all the Yahoo! traced roads and landuse areas, I prefer lots of data that needs some attention than none at all, especially if we had a "no names" type view to show buildings that need to be checked.

Thanks for the bridge/tunnel distinction, I tried to make the London Bridge ones a bit more consistent a year or so ago. That definition makes a lot of sense, very practical!

This is great stuff! Really good to see more detailed mapping in Snowdonia.

Thanks Harry. OpenStreetBugs might work better if it was a communication channel, i.e. you registered an OSM account and when your bugs are updated/fixed you are notified.

I've started putting the source tag on buildings these days, and I've been retrospectively adding them to buildings I've traced from a combination of OS and Bing. What's interesting about your map is that we already have three different values for OS data, none of which are precisely the value suggested on the wiki page!

Drat, Camden and Brent are now both above Southwark in the ITO table. I obviously need to get my bum over to Rotherhithe and Surrey Quays.

On XAPI, for those of us unable to run a mirror of the full OSM database it's really the main way to get at the data so further work on a reliable implementation would be much appreciated. I'd even be willing to pay a small fee for a subscription to a reliable server with a limited number of keys.

Andy, that's some seriously detailed mapping! I thought I was obsessive with my house numbering, I'm one of only a few urban villages in London to do this:
osm.org/?lat=51.46107&lon=-0.07265&zoom=17&layers=M

I don't think I'm willing to do gardens and highway edges, too much bother for a voluntary effort.

Isn't it very unlikely we'll get that level of detail across the whole country from volunteers? Our national base map offering is more likely to be at the level of road centrelines and landuse areas for the forseeable future.

I get the same message trying to download all power generators in the UK.

Just London works fine:

1,51.20,0.35,51.80]

Great, I'll give it a go.

Harry, any plans to also parse the bus route data released by TfL for OpenStreetMap? We have pretty patchy coverage at the moment, and, as Gregory notes, only an out-of-date render for end users.

Hi Ray,
