[Talk-GB] Announcing OpenEcoMaps (to geeks)
Hello all, After a long period of development I'm happy to announce that OpenEcoMaps is basically functional: http://www.openecomaps.co.uk OpenEcoMaps takes data about “eco” (green / sustainable) features stored in OpenStreetMap and turns them into KML files that are shown as overlays on the map, making it easy for people to find out where they can get a vegetarian meal, forage some wild fruit, spot a solar panel, recycle a can, pick up a car club car, or spend some money in a cinema. You can use these KML files on your own map, or in Google Earth; you can embed the OpenEcoMaps map in your own web site; or you can just browse around the site. See my blog for more details: http://tom.acrewoods.net/2011/04/11/announcing-openecomaps-to-geeks I'd really appreciate some help on some of the enhancements and bugs, I'm a full time policy researcher not a programmer and my hacking is pretty rough ready so more experienced hands would be welcome. https://github.com/tomchance/OpenEcoMaps/issues Regards, Tom -- http://tom.acrewoods.net http://twitter.com/tom_chance ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

The only 60 mph signs that need another tag are those rare cases where a single carriageway road does have a numeric speed limit. Fyi, about 95% of currently mapped speed limits in GB at speeds of 60mph and 70mph speed limits were already tagged as 'maxspeed=60' and 'maxspeed=70' when I first looked at this about 4 weeks ago leaving only about 5% tagged as national or nsl. I have been converting this remaining 5% over the past 2 weeks (with a brief delay while we discussed the principle on talk-gb after a reversion of one of my edits). I have had no complaints from others to my changes and only one reversion of one section of the A1 as I mentioned in my post. I take this as broad support for the changes. By tomorrow there will be next to no remaining 'national' and 'nls' speed limits in Britain other than in your patch around Macclesfied which I won't touch any more. There are also a small number (another 5%) of roads that are not in a recognised mph format, either because the mph is missing or because it is in km/h or for some other reason. I will be doing a copy-edit pass on these either fixing them if it is obvious or marking them with a fixme:maxspeed tag if not. I should be finished with that in about a week.

Really? Perhaps we were reading different discussions, but what I saw were: o People saying national != 60 mph o People saying don't make it harder for the mapper I'm guessing that you prefer a single numeric speed limit because it makes things easier to parse by e.g. the ITO World maxspeed layer, but surely changing the data to match the application is the wrong way around? I don't mind you always ensuring that maxspeed is numeric, provided that information isn't lost in the process - so if you complete your edits to indicate that, despite what the maxspeed tag is set to, the speed limit sign actually says national, I wouldn't object. This default (and the one for 70mph for motorways and dual-carriageways) was including to avoid burdening the mapper with another tag to add in most situations. The only 60 mph signs that need another tag are those rare cases where a single carriageway road does have a numeric speed limit. If you choose to change where I've mapped to maxspeed=national to maxspeed=60 mph; and some other tags to indicate that it is actually national that's not a burden to me in the slightest! I can still map maxspeed=what_the_sign_says as I have been doing. Cheers, Andy ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

I noticed that this had happened overnight to a road near me, and messaged the user to draw his attention to this discussion - without twigging that the 'PeterIto' I was talking to was actually Peter Miller of ITO (I can be a bit slow on the uptake sometimes)! Having followed this discussion, I must say I'm rather surprised that Peter has done this without at least adding a source:maxspeed or maxspeed:type tag at the same time. -- Steve ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

Maybe it would be best to tag that as maxspeed_sign=what_the_sign_says. Probably maxspeed:sign would be better than maxspeed_sign. I do however think that maxspeed:sign could be clearer than maxspeed:type and both are better than the maxspeed:source which is misused at present in some places. If we then have suitable national defaults for speed limits of different values then I think that could work well. I believe that it is only maxspeed values of 30mph, 60mph and 70mph that would ever need a maxspeed:sign entry and are therefore the only ones were an agreement is needed on suitable default values. Incidentally, has anyone got an example of a 30mph zone starting based on street lighting that is not also signed with a suitable 30mph sign? I reaslise that 30mph signs were non-existent in 1934 when the 30mph urban limit was introduced. However...I would be surprised if in the last 75 years there hasn't been a full roll out of signage, if only because it is likely to be much more effective at getting people to slow down. I note kev js1982's comment about 70mph speed limit signs in Scotland. Incidentally, I recollect that there was a proposal recently to covert all 'unrestricted' signs in the England and Wales to numeric format to avoid any confusion.

Re: [Talk-GB] Maxspeed tagging for the UK
I apologise for editing too soon and having taken silence as agreement. I will not any more editing of maxspeed while we resolve this issue. In my defense I would note again that a considerable percentage of unrestricted roads in the UK had already been tagged in numeric format and that my manual edits were about improving consistency rather than going against the majority or even a large minority. Personally I don't care as much about which standard we adopt as to the idea that we have a preferred format that is documented and is compatible with other countries schemes and which is readily available for routers to use and is implemented! Mot people will hold off mapping speed limits until this is resolved. If we use the 'national' approach then in my opinion routers must have simple unambiguous access the relevant numeric speed which can either be included in the maxspeed field or in some suitable supporting field. If we use a supporting field then we need some useful defaults. In either case we need to agree which we prefer and what the text is for single carriageway, dual carriageway and motorway.

And if pushed I would have said that the consensus was maxspeed=national. The discussion never pursued a number of outstanding issues. The most important of these being whether it would be useful to identify dual carriageways in general, rather than specifically for identifying speed limits (I believe that it would, the post-processing effort is high and there are sufficient anamolies to make it difficult to identify all satisfactorily). Others relate to relevant speed limits for different classes of vehicles, and finding suitable names for the additional tags. I was unhappy
