Abbey names are a little bit higher class than footballers. I'd forgotten about The Bomber Estate in Maidenhead, although the council prefer Halifax Road: all named after British bomber aircraft of the WWII.

Given that the one thing one knows about a watershed is that it is not a water feature, I don't like using this type of tag (anymore than waterway=boatyard). A watershed is really an abstract concept, whereas on the ground there may be a range of features (in hilly or mountainous country we might have natural=ridge), but we may still need waterway|natural=watershed where the lie of the land is not so obvious). Of course the names of tags are merely syntactic sugar - if I want foo=bar to mean something then so be it - so I'm not going to get too hung-up about the specifics. I think the only important thing is to use a relation.

The US has quite a lot of data on watersheds: most available freely. Take a look at US Interactive Watersheds. Mapping them is interesting for all sorts of reasons: pollution, ecology etc. I'm glad someone started the ball rolling.

Yes it can be done from the topology: if the topology is complete and correct. I've never thought of the process of finding isolated DAGs in a relational database as 'easy' though! Certainly levels in a watershed/river basin would be much better assigned through some automated algorithm. Something will eventually be needed given that we have river, navigable, river, not navigable and stream which doesn't really give enough discrimination for sensible rendering.

I think it's easier to define the boundary (watershed) of a riverbasin, than try and tag all the relevant watercourses appropriately (similar to admin boundaries vs. is_in). Since most watersheds are often features of interest (ranges of hills or mountains) these can be marked with a relation. So perhaps boundary=watershed on a relation would work? OK then you have to find all the watercourses within a bounding polygon, but surely that's trivial. :-)

You have a tag sport=skiing. Osmarender treats all sports tags as areas not ways. You get the same thing with cliffs with sport=climbing. A bug I suppose, but probably not likely to be changed soon.

I'd add something to the talk page for ford on the wiki, for now (a cut and paste of the OP (w/o OSGB refs) would be good. There's very little on ford, and AFAIK they are not rendered so how they get tagged is likely to be pretty free format. Pictures would be helpful. One thing I've noticed at the only ford which I've mapped is a height gauge showing how deep the water is. Probably a nice to have: perhaps height_gauge=yes, or similar. Mapping fords in the UK is probably pretty abstruse, but there must be many other places in the world where most crossings of waterways are fords and will require a range of other tags, such as crocodiles=salties;freshies or crocodiles=no: important info if its a bit deep and you've stalled!

My initial impression is that the surface tag would cover many of these if attached to the ford node. I don't know if ford applies to ways: I certainly would not use it for Holy Island, this is a road with unusual access conditions.

Locations are better given in lat/long rather than some (apparently) proprietary format (and I say this despite my user name :-)): (Barwick 51.852 0.0109 etc.

Thought it might be fun to see a before and after, so have used ITO's OSM Mapper to generate an image of the edits from the past week. Well done one and all. Look forward to seeing the MK map fill out in a couple of weeks time!

lost a link in the last message, hope this works Christkatholische Kirche.

Whereas robots can perform very useful functions, they, alongside large scale automated imports, can also seriously alienate contributors. Pretending that a robot which makes alterations without consultation is somehow equivalent to errors made by contributors whilst editing data with an editor of their choice is casuistry. Nor, as daveemtb says, is retrospectively pointing to wiki pages an acceptable method of announcing one presence.

Given that xybot has done 1.5 million edits I presume most of these are harmless, and some even beneficial, and fortunately few harmful (the following is seriously wrong and I'm surprised it has not caused problems in german-speaking countries: "denomination|christ-catholic" => "denomination|catholic#religion|christian", see ). I do think it is up to the community, however, to decide what, when and how such robots run. Surely a robot can run a pre-pass and generate lists of proposed edits, and even mail them to those who last edited the object. I don't really like the idea of having to consult a wiki page every month as suggested by Tom on the off chance that some global edit will change some tags which are of importance to me. Tag spelling corrections are better done by adding the correctly spelt tag (obviously does not apply in Richard's case).

It also adds tags of religion=christian if in xybot's opinion a given denomination is christian. Seems a rather dangerous activity for some areas of the world where the only valid tag for any group than one's own is religion=heretic.

A more productive use of programmer time would be write something which could cope with capital letters and spaces in the render chain!

If you use potlatch you can click on one of the relevant ways (e.g., a quick look suggests one problem is that Duke Street & London Street have been merged - surprisingly easily to do accidentally in Potlatch, as I found last night), press "h" to get a history of the way and there is an option to send mail. Its always best to send mail rather revert: particularly as the new API beds down and a series of edits may be incomplete. HTH.

PS. It would be nice to see the Oracle on the map, and surely not all the inner ring road is called "Inner Distribution Road".

I use a Garmin etrex Summit HC. I've certainly noticed it losing sense of its surroundings on single deck Barton buses (usually when stopped at a bus stop for a long time). I noticed the new style trains to London don't allow any signal at all!

I went out in the car last night to grab some more traces around Arnold, but its nigh on impossible to collect POIs as one goes. I think the top floor of the bus offers higher productivity. Now I've got some basics done I'll probably focus on these three suburbs. Which just leaves Bestwood Park and Bulwell for later!

Make sure you have a version JOSM v1529 or higher. The real problem is with edits on version 0.5 data not loaded onto the server before the upgrade. With the new API the data will include a version number of the way/node/etc, and without this (as in 0.5 data) it's not possible to reload it.

Don't intend to do this at all. A friend used to live there, so I knew of its little peculiarity. Had to dig out an old address list printout to find the name!

Have a look at Information Freeway: http://www.informationfreeway.org/?lat=46.176358516011646&lon=7.550547317974489&zoom=14&layers=B0000F000T

I'd think there's a fair amount of work to be done in the area, given that the Punch & Judy is missing in Covent Garden itself (a pub I've avoided for years because I like to: a) sit down; b) hear what people are saying; and c) get served in less than a light-year), as is the Inigo Jones church opposite. A couple of other quick thoughts: the gardens of Lincoln's Inn Fields are incorrectly labelled. The Sir John Soane Museum, the Royal College of Surgeons and Cancer Research labs are all missing around Lincoln's Inn Fields, as are the historic buildings of Lincoln's Inn. All of these are important aspects of the fabric of London, and probably a bit less ephemeral than pubs these days (a reason why I'm reluctant to add stuff in places I haven't cased out recently).

If anywhere needs a bit of TLC in the Merseyside area its central Birkenhead: lots of roads missing in the centre, and the aerial photos are quite hard to interpret particularly around the tunnel entrances. I suspect that this is one of the places which at a superficial glance looks 'done'.

Try Duke's Wood, Nottinghamshire (map). This was Britain's first on-shore oil-field and is now a Nature Reserve, but with one or two old donkey pumps preserved. The road layer on GoogleEarth shows lots of tracks in this location, presumably the former access roads to the wells. I'm not sure how many are really extant on the ground. Not completely sure how accurate the data is either: the 4 wells here are all shown S of Pudding Poke Wood (check on NPE), whereas the NWT map of Pudding Poke/Duke's Wood shows 5 wells still in situ. I can certainly remember seeing 3 a couple of years ago.

Amazing, new version of OSM Render has fixed this issue, also house names show better. I'll now restore the addr data (only from other tags).

I've added from memory and the Yahoo mapping, the Cassonsgrat Cable car and the run from the Vorab Geltscher to Alp Ruschein (now black, used to be red, I think). Someone will need to check these on the ground: and perhaps add the Cassons freeride route! This is roughly 50-100 metres W of the line of the cable car.
