It's like when people drive into the sea, or along railways because the Satnav "tells them" to do it... I'm not a fan..

Hello and welcome (o:

I wish I could 'like' your answer on here, alexz!

to add to the mix, there is also highway=byway in the UK....

I agree with the original rant, I have to say.

I also think that mapnik could do with a bit of refining when it shows the fields, as it currently starts at zoom=9 but not really until zoom=7 or zoom=6 (dependent on monitor) do the secondary class roads actually become visible against the fields....

Agreed - I think waterways would tend to be bridged over (unless sunk into a pipe, which is clearly a tunnel; or physically tunnelled canal style through a hill, or something.

I know exactly what you mean at Finsbury Park there - I used to drive under it every day (shudder) - that's definitely a series of metal bridges that you travel under...

Now, looking at: http://wiki.openstreetmap.org/wiki/Key:bridge

we have the following text:
In case of an undercrossing/underpass you have to decide on the basis of the construction if you are over a tunnel or on a bridge.

as well as:

When there are several bridges close together it is sometimes acceptable not to tag them as bridges, but to tag the single road below as going through a tunnel.

which is helpfully ambiguous!

Ooo, now the tunnel vs. bridge discussion is interesting... I've always used the rule of thumb that design of the bridge/tunnel is the primary consideration. For example, a road intersection over the top of a diagonal river/stream, like the one at New York http://osm.org/go/eu_9yw66e-- which on a site visit is clearly a sunk pipe to tunnel the stream under the road.

Whereas at other places, such as the Dog in a Doublet http://osm.org/go/eu74nFihD-- the design is clearly a bridge...

Now, in these examples a rule of thumb around wide vs. long could currently be applied... but conceivably in the first design the tunnel could be quite wide with just a single track lane going over it, and in the second design the road going across could be a ten lane motorway....

Just some thoughts

PD?

Good going - well done!

Select that you would like contributions to go to the public domain. Then everyone gets the data with no strings attached. Much better for the good of the world...

(and thanks for the other suggestions, guys... I'll have to save for the etrex - see if I've got any cash left over at the end of the month!)

Hi Bitic, Yeah, the iphone's GPS trails aren't too accurate as they don't connect to as many satellites as a dedicated receiver. I was using one walking this weekend (actually my mate was using it, for lack of working GPS on my part!) A couple of times it located us completely randomly in strange places so I don't think it is totally reliable for hill walking!
Cheers

Hello, long time no speak. I've been adding more to SG9-14, CM23 and they've not appeared either... I guess there's a problem...!
Chris

Yes, and yes.

Hi mce, I agree with JoshD. You could consider marking all of your contributions as public domain, where the derived work allows for this to happen. After much consideration, that was the conclusion I came to. I don't really care whether anyone derives maps or anything else from my work, nor do I really care if they claim it as their own, or charge people for it; as the more places that this sort of data exists, the better, as far as I'm concerned.

Cheers
Chris

NW1 is never Herts, surely? (o;

I've only seen maxspeed= on a node where enforcement=maxspeed on the same node.

another classic is when streets are wholesale renumbered for no real reason - madness!

It's good, but there's still some annoying bugs - would have thought it won't be long before they're ironed out though as progress is amazing.

My personal view is that I want the data I contribute to continue to be available and of use, even if the worst were to happen, and OSM were to disappear, so I opted for PD. Yes, some people might then try and sell it, but there's more chance others will continue to provide it for free so they will be less successful at this.
