[Talk-us] Fwd: IronChef for geonerds in NYC
Love data and want to meet people? Have a look at this event in NYC on Sunday, 26 February 2012. You'll be in Arlington for the DC Hack Weekend on the 18-19th anyway, so extend your visit and meet more data-folks. -- Forwarded message -- I'm helping out some academics organize a hack day in NYC in conjunction with AAG. If there are any OSM folks in the area you think would be interested send them along. Should be a cool mix of folks that usually don't intersect each other. Details here: http://www.floatingsheep.org/2012/01/iron-sheep-has-landed-location.html thanks, sean -- Sean Gorman PhD.

I've had this question before too. For perfect routing the ideal situation would be to have the address tags be on a node at the exact location that you want routers to route you to. So the front door of a house or the main entrance of a store. Of course that often doesn't work. Multiple entrances and special purpose routing (to the loading dock?) for example. I see two different cases really. For residential addresses which usually stand on their own, I tend to put the address on a node by the door or stairwell for apartments. If you search for my address, it will take you to within inches of the first step of my stairwell. You're on your own to find the apartment number :) I don't think postal services will never use OSM so I don't see the location of mailboxes as being very important. For "real" POIs like shops and such the address really needs to be on the same object that has tags that describe whatever it is. That way you can click/tap on a POI or search for a business name in nominatim and see that Fred's Barber Shop is at 123 Main Street. For places that are mapped as a building or POIs inside of a building either nominatim or routers (or some combination) should probably look for entrance=main/yes nodes along the perimeter and route to there by default. That's still not always clear though. With your examples: Does the address go on the area defining the entire resort or on the main building? I would probably argue the main building since that is where you will usually want to end up when routing. Especially if individual buildings have their own addresses. But then you may have to duplicate name and other information on the land area and the building. And then which one will nominatim find first? I'm sure someone has thought of a way to use relations for this but... meh The mall example doesn't seem too hard. The mall and shops within it can have their own addresses. Again, look for the nearest entrance=* tag for routing purposes. And I suggest entrance tags to solve this problem: http://mapq.st/Ak9fC3 - Clearly the starting point is ridiculous. It is just finding a routable way that is nearest to the centroid. I suppose if the inside of the building were mapped... I would think that sharing an address would be fairly rare. Most places at least have unique suite numbers, don't they? (which I map as addr:suite even though it isn't used by anything yet) I think county's GIS office associates addresses with land parcels so that's not very helpful for OSM.

[Talk-us] Exactly what does an address correspond to?
Presumably the answer is "a mailbox". But we generally map buildings and properties long before we map mailboxes, and when used as a location one expects an address to be the actual location the mail is intended for, not the location of the mailbox (which may be e.g. out on the main road or in a central location). So back to the original question: exactly what should an address correspond to in OSM? For example: *A large resort hotel with one address for the main building/hotel as a whole and others for individual buildings. *A mall with one address, but some large stores have their own addresses. *Two office buildings that share an address. How do GIS professionals usually handle these issues? ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

The fact that double yellow means "crossing the centerline markings for passing is prohibited" and not "crossing the centerline markings is prohibited" is quite significant. You can, if it is safe and not otherwise prohibited, make a left turn across a double yellow. You can, if it is safe and not otherwise prohibited, make a U-turn across a double yellow. The only sense in which a double yellow prevents crossing "if there are no intersections nearby", is if any place where someone might turn is called an intersection. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

The reason for the complexity and seeming overuse of ways and restrictions is that I am mapping legally binding pavement markings along with the actual travel ways. It is my understanding that pavement markings are as enforceable as stop signs and traffic lights and, therefore, are subject to key:access type treatment, such as through use of turn restriction relations. I don't know about Pennsylvania, but here in Florida a single white line does not legally prevent crossing. But even if it did, we don't map a double yellow as a median. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Looks more like carelessness than vandalism to me. It's just one way. In this case, I'd just repair it (done that already) and move on.
