Hmm, how do we know these exist except from Google Maps. If that is how we found out about them then we're deriving this data from Google. Doesn't seem like a good idea for me. Let alone using Google Maps to name the runway.

GNIS does have names for islands in this part of the Gulf. According to Birding UAE both islands are private without access. One of them may still be a breeding site for the Socotra Cormorant.

fee=yes/no is a more or less universal issue in UK (particularly railway (train) stations which are more or less 100% fee. Toilets are increasingly only open with restricted hours, once the decision has been taken to close them the opening time is determined by staff hours. See Gail Knight's blog for a comprehensive introduction to the issues.

There is a good tradition about obsessing about mapping toilets and sanitation facilities on OpenStreetMap and often for very good reasons: How to map open defecation areas".

The usual way to mark a pass is with a node tagged https://wiki.openstreetmap.org/wiki/Tag:mountain_pass=yes with a name=* and ele=*. This could be a node on the way marking the trail or a single standalone node.

For part of a longer trail which both have names follow the suggestion of FK270673 (a relation for the longer trail and its name, the way for naming a section of the trail).

There is a single use of a tag for trailhead with a value of start. I'm sure marking trailheads has been discussed on one of the mailing lists in the past. Feel free to use the existing tag or invent one of your own. The bulk of mapping footpaths in OSM is European-based where most footpaths form a dense interconnected network, so the notion of a trailhead is less significant. Signposts (finger posts), waymarkers and information boards are much more likely to be mapped.

Check out Lonvia's Hiking Map to see which trails have been mapped worldwide: at large scales this shows a lot of hiking related detail.

There might be slightly more accessible sources (e.g., the html for the map key).

There is a Japanese local chapter with a website here: http://openstreetmap.jp/.

There have been several recent events, some associated with conferences or HackforJapan events. Several members of the Japanese OSM community are active on twitter (Ikiya, Mapconcierge) and Ikiya has a blog.

Nice edits, welcome to OSM.

To add a 'phone number, select the advanced edit option (at the bottom of the left hand panel) and the tags associated with the object are displayed. Just add a new tag with key "phone" and put the phone number in the value field. As OSM allows free-format tagging, the editor only supports a limited subset of the more popular values.

To realign the power-line you'll have to a ground survey: this need be nothing more than notes on a sheet of paper as to where the powerline now runs. Finding where it crosses streets is the easiest way. I imagine it would be useful to use other landmarks (prominent buildings etc) to help fix the alignment. Walking papers provide a facility for printing out OSM maps or Bing aerial imagery which are designed for this kind of data recording.

Aerial imagery is always out-of-date to some extent: one of the powerful things about OSM is that one can create maps of one's own neighbourhood which are much more up-to-date than other sources. This might be the re-routed powerline, the new housing division, a major road realignment, or just a nice new pub or restaurant.

"Dénomination de voies

* Il est proposé les dénominations suivantes, pour le réseau de voiries situé dans le lotissement de la Cerisaie :

1. rue de la Cerisaie : entre l’avenue Lénine et la place du Jardin-d’Alençay 2. rue Eugène-Bizeau, poète libertaire tourangeau, à l’ouest de la rue de la Cerisaie, ayant pour limite cette dernière et la place du Jardin-d’Alençay 3. rue du Côteau-de-Loire, à l’est de la rue de la Cerisaie et ayant pour limites cette dernière et la rue Marcel-Cachin 4. place du Jardin-d’Alençay pour l’espace public situé au nord de la rue de la Cerisaie, en limite sud du cimetière."

Bravo, all contributions in North Wales are very welcome.

As you say there is a huge amount of detail missing, but familiarity with the area combined with Bing and OS Open Data do help. I've got a lot of geolocated photos from sporadic trips which I've started to use together with Bing aerials to add detail.

As for the water pipes: they do not show up on the main map (the Mapnik render), but they are shown on most garmin maps derived from OSM (e.g., talkytoaster & All-in-One): I've just checked both of these for the pipes coming from Llyn Llydaw to Cwm Dyli power station. Mapnik does not render everything, and is not specifically walker-oriented. It's best to keep the correct tagging, and persuade the authors of the renderers to add overground pipelines. Changing the tagging to get something to show up on the renderer means that it wont show up properly on people's Garmin units: and its those which are far more likely to be used on the hill.

Guys, it's way easier to recover accidental deletions.

If you use Potlatch 1 you can just click 'u' and it will pull back deleted ways from the server. These will show up as locked red ways, you can unlock a way and just save it back to the server. Potlatch adds a note about reverting to an earlier version.

JOSM has a changeset history tool which allows recovery of earlier states, but this is rather more sophisticated, and requires a certain amount of experience & confidence before using in earnest. As it works on data offline it is worth seeing how it works with one of your own changesets just in case you accidentally end up loading the data.

I'm a bit concerned to learn that contributions are being deleted and replaced by imported data.

@firefly. I'm sorry its news to you but on the wiki and IIRC on the OSM site there have been flash messages about the license change for several weeks.

The likelihood of a change in the license was something I was aware of from the wiki at the time I signed up in Dec. 2008. There has been a huge amount of discussion about this since (if not before) the Manchester SotM conference in 2007. The talk-legal mailing list is more or less dedicated to thrashing around the license issue. I don't think a day goes by without changes on the wiki to license related information. The JOSM flash screen has information about it. There are any number of blog posts and diary entries about it. AND it's been a particular talking point for Australian mappers, in part because of NearMap and Government Data licensing terms.

Obviously its possible to miss all this: and then it comes as a nasty surprise. But to say "all this crap about years of discussion" is wrong. Please don't blame others for not keeping your ears and eyes open.

@Wallclimber21: you seem to have a very narrow view of how data from OSM might be used. It is not just the tiles.

I for instance use OSM on my Garmin: there is nothing to stop me having a final CC-BY-SA OSM map and a current ODbL OSM map stored side-by-side on my Garmin. Of course re-combining the data is a different issue (at least outside of personal use), but that's exactly why the license change exists.

I have stated before that I have no desire to see mappers and their data lost from OSM, but I also know that people have different perspectives and attachments to various kinds of license. Unfortunately no-one has found a way to realistically store data with a license which can meet everyone's desires and needs.

I respect others right to make their own decisions according to what is important for them. I'll be sad if they don't accept the new license and CTs, but I recognise that this will happen (no-one can expect unanimity in a group of 200,000+). Personally, I may have to do some re-mapping. BUT, I'm certainly not going to call anyone names.

I must agree with others here: do not make any kind of pre-emptive edit on the basis of whether users have or have not agreed to the new license and contributor terms. It will just make life difficult for everyone.

There are plenty of things that you can do with respect to data which is not currently licensed by all contributors under the new terms. For instance, you can go and do a survey of areas affected: I'll bet things have changed, additional POIs can be added etc. A survey is a positive contribution at any time.

But most of all, you can work to persuade people that their contributions are valued and that we'd love their work, effort and insight to continue within OSM. Pre-emptive deletion and calling their edits 'problem edits' does not contribute anything to achieving that goal.

In your case I think the answer is straightforward.

Some roads are both closely aligned with GPS traces & Bing imagery. Others are not: a quick inspection of some of these roads showed them to have source=plan:at. I believe these are imported data with a lower level of accuracy than OSM data mapped on the ground.

The best approach is to survey these roads using a GPS, you can then check the alignment of the Bing imagery and have the best of both worlds: a recent ground survey and the extra information from aerial imagery.

Richard Weait's golf map overlay is currently off-line (he's updating the database) but this works with the well-established (aka proposed) tags.

There appears to be good imagery from Bing for your home town. This is not accessible through Potlatch 1 editor, but if you hover your mouse over the edit tab other options are available including Potlatch2. If you click on Potlatch2 and then choose the Bing imagery background you should be able to add much more information to OpenStreetMap.

Best of luck.

Camino de Santiago

I don't think that the Via Algarviana or the Via/Ruta de la Plata have OSM relations.

I don't think its that easy to search just on relations (unless Nominatim does walking routes), thus mainly the relations tend to be added to the wiki:

Projekt Jakobsweg

Agree that this map is misleading.

A substantial number of power-lines have been edited and tidied up since the TIGER import (e.g., NW PA), at least in part because they show up clearly on the dupnode map and can easily be cleaned-up without interfering with anything else.

Nice link, although in many places its a heat map of mappers mapping! But it is another good handle of on-the-ground mapping. It's probably a lagging indicator of on-the-ground mapping compared with pubs, because not every OSMer is a cyclists, but most seem to like pubs.

There are many nice PDF cycle maps on the site too: http://www.spokeseastkent.org.uk/maps/.
