[Tagging] Patisserie?

2010-10-28 Thread Valent Turkovic
I'm using Mapzen POI collector and current version of Mapzen POI
collector uses abandoned feature patisserie:
http://wiki.openstreetmap.org/wiki/Abandoned_features

AFAIK it should be tagged like this:
amenity=cafe
cuisine=cake

Right?

I'd say this depends on the place, by reading the title I thought you
were writing about a "shop". cuisine=cake doesn't sound right to me,
although this represents 0.1% of all cuisine tags. There is 61 items
tagged as shop=patisserie which isn't overwhelming either.

Not in France. It's really a shop like a bakery (and is often combined but
not always). You may or may not be able to eat on place (tea room). It's
surely not a 'cafe' although some 'cafe' provide cakes but they come from
the nearby patisserie.

I'm reading this from wiki, so maybe I misunderstood it? Any
clarification would be appreciated. How to tag patisserie? It is a
shop that main business is selling cakes, but also has ice-cream and
cafe.

[Tagging] Super-relations or not (was: Relation member_roles from Osmosis import)

Aha.  Now that's interesting.

To me, this says we really ought to be using super-relations for route
relations, rather than a single relation with roles tagged, for 2
reasons:

1) The common way, up to now, for storing routes that alternate between
single- and dual-carriageway has been to leave the single-carriageway
parts without a role, or with the role "north/south".  This makes the 
order of the members of the relation meaningless, since you
can't traverse the ways end-to-end in the specified order.

This could be solved by adding the single-carriageway sections twice
(once with "north" and once with "south"), but at that point, why not
take the extra 5 seconds and do super-relations?

2) If the direction of a road (e.g. north/south) is indicated by roles,
how do you refer to it elsewhere?  For example, if you have a
destination sign that says it goes to I-75 Northbound, and all of I-75
is in one relation with roles for "north" and "south", how do you refer
to just one direction of the road?  You can't refer to the whole
relation (because that doesn't reflect what the sign says), and there's
no clear way to refer to a role of a relation.

With super-relations, this isn't a problem... there would be a
subrelation that unambiguously refers to just the northbound or
southbound part of the road.


I really think that super-relations for routes are the way to go... all
the methods are really equivalent, but super-relations are easier to
deal with programmatically, preserve a little more information, and are
not really any more difficult for users/mappers.

If anyone has a compelling argument against super-relations, or for
single relations, I'd like to hear it.  Supporting both seems really
pointless, and I think it's about time we picked one or the other so we
can develop proper support for route relations and tools to support them
moving forward.

yes, absolutely, the relation with role is very limited, one more reason is the 
checking tools for completeness. there is a relation checker and it will find 
one single ordered and connected set of ways. easy to verify broken routing. if 
a relation passes it also means all ways are connected, no duplicates in the 
route relation …
it's almost a routing graph

[Tagging] levees

2010-10-28 Thread Nathan Edgars II
Is there a standard way to tag a levee? It seems that highway=track
embankment=yes would work for the vast majority of cases, but there
may be some that service vehicles can't drive on.

Also, levees (at least in swampland) often have an associated adjacent
canal without its own name. This is sometimes called the '[levee name]
borrow canal' (http://www.google.com/search?q=%22L-30+borrow+canal%22),
since the fill for the levee came from what's now a canal, or simply
the '[levee name] canal'
(http://www.google.com/search?q=%22L-30+canal%22). Should this be
separately tagged with such a name, or is it assumed that a canal next
to a levee shares a name (like a sidewalk next to a road)?

Forward and back don't really work if the direction of the way gets
reversed for some reason.

Where I'm at, most of the streets AND avenues are numbered away from
downtown Tulsa, and we're far enough that any three-digit street looks
about the same as any three-digit avenue that nobody bothers to remember
them unless they happen to have an address on it.  Instead, you're
likely to get directions like "Turn right after the truck stop and turn
left at the second stop sign" from someone.  Being one of the few
landmarks actually visible from the street far enough in advance to
actually navigate by in the woods, yield and stop signs often end up as
navigational reference by themselves.

Look in Portland, Oregon around the Rose Garden Arena for some good
examples of both.

Why not use relations for stop sign applications similar to how
enforcement relations work?  It really seems silly to use a tag that
expects people to imprecisely describe direction relative to four
cardinal directions, or use degrees or radians, when you can essentially
draw a picture.
