Re: [Tagging] maxspeed=signals
Hi. That's how it's documented and defined, but I fear, if you look into maxspeed tags of countries not using the metric system on signs, we probably have many bugs in values without units, if you use that assumption. It's similar to everything else: If there's nothing declared, you don't know if it's wrong or missing. If there's no maxspeed at all in the database, we don't know if there's the national default or if nobody cared about maxspeeds there, yet. That's why I want to ALLOW a unit information even where it's metric. regards Peter Am 26.06.2012 17:03, schrieb Paul Johnson: On Jun 26, 2012 6:03 AM, Peter Wendorff wendo...@uni-paderborn.de mailto:wendo...@uni-paderborn.de wrote: I would prefer to allow (not require) an additional unit information (mph, km/h), simply to encourage data consumers to deal with them as they are usually added by users.

I don't think it's useful, as we are still speaking about legal speed limits, while often lower practical speed limits are the limiting factor, and no router should assume a maximum time a particular vehicle needs, as there may be a traffic jam as well as ice on the road and so on. The default limit I see similar (if it's not the highest one, which it is in all cases I know and AFAIR have been reported in this thread, yet). regards Peter ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

I think that estimation of slowest possible trip is not something we should be thinking about. In my country, and I assume most others, you must lower your speed if the road conditions are bad, even if there are no signals. That is not very different from signals that lower the maximum speed if there is rain, fog or something else. Let alone traffic jams. I think such cases should be handled by other, real-time services. We should only concentrate on the best (fastest) case scenario.

Re: [Tagging] Tagging Blue flags (Foundation for Environmental Education's Blue flag criteria for beaches and marinas)
Dana utorak, 26. lipnja 2012., korisnik Simone Saviolo simone.savi...@gmail.com je napisao: Yes, in fact, that's what I meant. Every single beach area in the municipality has been awarded the flag. I am still a bit unsure, though: do you know of cities in which only some of the beaches/marinas have the flag, and others don't? I don't live on the sea, so I am not sure. But whenever there is talk about blue flags here (Croatia), it mentions specific beaches and marinas, never towns or regions. I got an answer about gray flags on their site: The grey flags are Blue Flag sites not in Blue Flag season yet: this means they have been awarded the Blue Flag, but will comply with all criteria when their season starts, later in the summer. Best Regards, Sophie Bachet Blue Flag International Director So some beaches are only blue flag compliant during some seasons. I think this is too much information for osm right now. fee_blue_flag=yes should be enough.
