It is annoying the stale content that some devs/providers provide, maybe it would encourage them to put some effort into updating the content for frequently. Something along the lines of http://wiki.openstreetmap.org/wiki/Proposed_features/temporary would help, though I think it would benefit from some way of specifying that the start end dates are estimates only. That proposal seems to be languishing, though. -- Cheers, John ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Somerset Levels Flooding
Define slow for a printed atlas? Should we be pulping them each minute? Day? Week? Printed atlas!? So insensitive I carry a globe around. I wonder however what about the providers that do want update their data, say, daily are at a disadvantage if we don't mark these cases. Hence why I suggested maybe a month or so in this broken state maybe we should edit. These parameters will vary between mappers but a threshold maybe we could agree open here. Maybe some still consider estimated 1 year bridge closures is not long enough to consider updating the map. Also maybe it should have more weight to the mapper local to the area (hence your Putney example). And/or how quick it will be monitored and updated.*Shrug* Unless, of course, there are people who are deliberately looking for an argument... ;-) Date: Fri, 7 Feb 2014 12:52:16 + Subject: Re: [Talk-GB] Somerset Levels Flooding From: gravityst...@gmail.com To: rovas...@hotmail.com CC: l...@lorp.org; talk-gb@openstreetmap.org On 7 February 2014 12:37, John Baker rovas...@hotmail.com wrote: Always to play the devils advocate.

Re: [Talk-GB] Somerset Levels Flooding
Hi - I do add temporary things such as road closures, construction sites. Generally only if it will be there for a while, e.g. a month or more. I agree with Brian's perspective.

The water I agree is likely to be a bit inaccurate and isn't going to help with the routing, but like a road, those areas will be wet for quite some time (weeks to months), so as long as the person doing it keeps it relatively up to date, I guess there is no real problem.

Re: [Talk-GB] Somerset Levels Flooding
I think it would be useful to have a means of indicating road closures etc which are different from simply pretending the road doesn't exist or doesn't allow certain users for a while. This would allow renderers to mark closures rather than just gaps or not visible at all, so people see there is a problem; so that user types can be indicated (sometimes bikes can get through a closure, but not cars, or cars but not trucks); and so that (perhaps estimated) end dates can be given so that the restriction can be ignored when the closure didn't get removed - they are easily forgotten. Routers too could say 'I would have taken you this way, but it is closed when you want to travel' I was surprised someone hasn't already removed a section of railway at Dawlish yesterday! But it would be much better IMO if the railway remained, but marked as closed so the map could show, eg, a big red X at that point to illustrate an anomaly, rather than a short gap not really visible at all but the largest scales, David Hi - I do add temporary things such as road closures, construction sites.

Re: [Talk-GB] Somerset Levels Flooding
How about having theKey: accessandValue: no or possibly Value: delivery or customers if its roads. If you wanted it to showup on the map as red, setting the Value to 'private' as in keep out its a building site would work.

Re: [Talk-GB] Somerset Levels Flooding
Indeed this is surely the right approach. Many people use OSM inside products where the map data is updated rarely: all the offline map apps for mobile come to mind. Temporary states have no place in these apps, and it’s unfair on their devs to force them to work out a long-term state to offer their users. - L On 6 Feb 2014, at 14:36, Andy Allan gravityst...@gmail.com wrote: On 6 February 2014 09:43, David Earl da...@frankieandshadow.com wrote: I think it would be useful to have a means of indicating road closures etc which are different from simply pretending the road doesn't exist or doesn't allow certain users for a while. I work on the principle of marking the permanent state of features, as much as possible. Obviously everything changes, but if a situation is deliberately temporary (e.g. a road closed for crane operations, or for a fortnight for digging, etc) then I don't change the 'permanent state' of the feature. We had a trunk road in Putney that was one-way for three months, but I didn't change the map to correspond since it was clearly not permanent. And I'd encourage people not to mark flooding as natural=water, or removing bits of railway when they are certainly going to repair it, or even adding access=no tags to something that might be fixed by the weekend. If it's deemed important by people to mark the temporary state somehow, then please use a separate tagging system.
