Wrong tags on Path 6 months ago

That is not wrong. highway=footway simply means "a path which is primarily intended for walking". You can use it with sac_scale=hiking if you like, or indeed a surface= tag.

The hazard of relying on commercial implementations of Open Source projects 7 months ago

I'm not sure that the problem here is "The hazard of relying on commercial implementations", more "The hazard of relying on CloudMade". It's not necessarily endemic.

Important unpaved roads exist, so needs a reboot 7 months ago

Aaaaaand done:

Important unpaved roads exist, so needs a reboot 7 months ago

Sigh, another badly worded wiki page.

The intent of the highway= tag has always been that the tags represent each road's importance in its nation's road system, with the hierarchy trunk->primary->secondary->tertiary->unclassified.

There are also a few "special" values: highway=motorway (a restricted access fast road), highway=residential (a sub-unclassified road for residential access), highway=service (a sub-unclassified road for non-residential access), and so on. But the trunk->unclassified hierarchy covers most of it.

This is 100% applicable to any other country, and indeed the wiki page says this - "The highway type helps indicate the importance of the highway within the road network as a whole" - but, in the way of wiki pages, has accumulated a bunch of cruft which serves mostly to confuse people. We just need to sort the cruft out, rather than implementing a whole "new set of standards", I think.

Nice work!

Bilingual street names for Slovenia 8 months ago

"don't rely only on Google Maps when checking street names"

Don't rely ever on Google Maps when checking street names. Don't even think about using it. It's a copyrighted source, and OSM contributors aren't allowed to use it - that's part of the contributor agreement when you create your account.

OpenStreetMap UK: what should we do this year? 8 months ago

Surfaces on paths and tracks. A highway=footway or highway=bridleway could be anything. For walkers and (especially) cyclists, a well-chosen surface= tag makes a huge difference.

Poor man's rendering 8 months ago

"I really fail to see why these are not rendered"

Because you haven't submitted a good patch. Where do you think the rendering rules come from otherwise, magic stylesheet fairies?

School Districts Boundaries in California 9 months ago

You can load shapefiles into Potlatch 2.

Random bus routes 9 months ago

"Was there ever a time when relations were not ordered?"

Yes. Relation ordering was introduced with API 0.6. Relations were not ordered in API 0.5.

Relation ordering is still optional and most tools don't make use of it. By all means order relations if it makes you happy, but with rare exceptions (e.g. buses that pass over the same section twice), ordering can and should be derived algorithmically.

What is OSM? The best free map of the world 10 months ago

No, Chris is right. We could have imported all of the OS vector data automatically and we chose not to. We could have imported all of NAPTaN automatically; we tried a few bits and chose not to.

The fact that OSM was a (partial) contributor to achieving the OS OpenData release (though the Guardian's Free Our Data campaign and the Cabinet Office's open data initiative were more significant) is hardly relevant. OS OpenData still did (and does) contain a lot of stuff that isn't in OSM and that we could have chosen to import had we wanted to.

What is OSM? The best free map of the world 10 months ago

Right, and it's a valid question to ask what methodology makes the best free map of the world; and, in particular, whether the community that (everyone agrees) is required to update the map grows best when presented with a 'fait accompli' imported map, or when it's able to evolve the map at its own pace.

You are welcome to draw your own conclusions on that score, but it's worth noting that the two best-mapped countries in OSM are probably Germany and the UK, neither of which has any significant imports.

What does the path say? 10 months ago

Only if you add meaning with surface/tracktype tags. Tagging, say, the 7Stanes and Coed-y-Brenin trails with highway=cycleway and nothing else would be misleading - there would be nothing to differentiate it from the common-or-garden urban cycleway or Sustrans rail trail. Happily, they do indeed appear to have surface/tracktype tags.

That's the point here. highway=cycleway has implicit meaning; look at 90% of cycleway usage in OSM and it means more or less the same thing. But if you want to overrule that implicit meaning, you can do so.

highway=path doesn't have implicit meaning, other than "here is a path of indeterminate construction". Unless you supply the meaning with both access and surface/tracktype tags, it's pretty much useless.

What does the path say? 10 months ago

That's absolutely it. highway=cycleway tells you it goes "whoosh" and you can cycle on it; it works in E&W and elsewhere. highway=path and an access tag doesn't tell you it goes whoosh in any country.

MapBBCode: free maps for everyone 10 months ago

Superb. Really hope this gets adopted widely.

A Social Without Groups 11 months ago

@Tom: and yet people post to the diaries, even though they're not as fully featured as Wordpress (though they're probably not that far off Blogger...), because it's where OSM people gather. People use the messaging system, even though it's not as fully featured as e-mail. Groups are just the same: we're not trying to out-feature Facebook, we're providing a service for our users. You try suggesting to a bunch of mappers that we all use, ooh, G+ and see where it gets you. osmf-talk refers ;)

A Social Without Groups 11 months ago

What really excites me about groups is that they actually reflect how OSM works at its best.

Everyone has their own focus for OSM. Sometimes it's locality: they want their village, town, city to be mapped well. In a few places we provide tools to help this happen - there are a few city/county-scope mailing lists at, and other places have their own Google groups or whatever. But that's incredibly patchy (most places don't have one), unscalable (if hosted at, and requires the sort of techie mindset that "does" mailing lists.

Often, though, it's thematic rather than local. My preoccupations are mapping the UK's National Cycle Network and its waterways. It would be terrific if there were somewhere to talk with other people of similar interest, so we could feed off each other and get the job done better, quicker.

Right now there's nowhere to do that. You can do it on a general-purpose mailing list (in this case, talk-gb), but you'll get howled down by the marauding wolves who have no interest in the NCN/waterways but have an opinion about everything. You can ask Mike to set up a mailing list at, or use the aberration that is the new Google Groups, but that's a barrier for something that should just be "hey, we're having a conversation".

I see your point, Alex, that "today OpenStreetMap enthusiasts gather in spaces on mailing lists,, Twitter, Facebook, forums, and Google Groups"... but honestly, I don't think they do. Not over here, anyway. Super-connected guys in metropolitan areas are doing so, I guess, but that fixes London and NYC and SF - not the rest of the world. Even here, where the stereotype is that all our mappers go to the pub, we have regular pubmeets in London, Birmingham, maybe Edinburgh and Nottingham, and that's it: a tiny fraction of the community. Most of the names I meet in the edit history are untraceable through our existing social forums; they really are just working in isolation.

I also really see this as a way to prioritise "local knowledge" at the expense of "m4pp1ng sk1llz". Right now it's easy to get the impression that OSM's most valued contributors are those who've made the most wiki tag proposals and who juggle an armoury of 537 JOSM plugins for their mapping. You know and I know these aren't the guys who make a difference, but it's not how it looks - and I think we're already seeing the first signs of the "Wikipedia effect", where the top 5% exerts such pressure to conform with their arbitrary rules that newcomers are warned off. Baking thematic, interest-based social features into the core of is a really good way to demonstrate what we care about.

Yesh, Mr Connery.

Bicester to Upper Heyford 11 months ago

Certainly open and connected. But the surface hasn't been marked in OSM so it's not clear how passable they are. Have a go and report back so the surface can be recorded on the map!

Copyrighting Location Based Facts? 11 months ago

No, no-one owns it. "Copyright" is the right to copy. If you have independently come up with the same fact, you haven't copied it from (say) Google. But that doesn't mean that you could just copy the fact from Google without coming up with it yourself.

All of this is very jurisdiction-specific but you may want to look at the 'Case law' and 'Statute law' pages on the wiki.
