I wonder if this couldn't be made a bit more generic to encapsulate
other time-frames within an establishment's opening hours.

For example in a restaurant:
opening_hours=Mo-Fr 08:00-23:00
opening_hours:breakfast=Mo-Fr 08:00-10:00
opening_hours:lunch=Mo-Fr 11:00-13:00
opening_hours:supper_buffer=Fr 18:00-20:00

This would allow a mapper to highlight important time constraints
relevant to a particular business.

Imagine also a public swimming pool:
opening_hours=Mo-Fr 10:00-20:00
opening_hours:public_swim=Mo 18:00-20:00;We 18:00-20:00;Fr 18:00-20:00

I'd propose that the sub-tags could really be anything a mapper finds
important to an establishment.  When displaying the details for an
establishment, I could imagine displaying a "timeline" for the current
day, shading in the general opening hours, and then putting a little
bar in rows below to highlight the "important" time spans within the
current day.

I think in this context, the reference to MAN is referring to the
human individual as representing the species, without referencing
gender.  Beside, human contains MAN so I think we're ultimately
splitting hairs here.

Ultimately the fact the tag is called "man_made" isn't really
important though; its just a logical category used to group related
items.  These tag names are typically used by the map renderer, for
example, to determine which icon should be shown on the map, etc.  So
when this data is consumed we'll typically see these values go away
anyways.

[Tagging] Ways that change names while crossing divided roadways

2010-04-24 Thread Tyler Gunn

I installed the Garmin OSM map for my area and have been using it while I
drive around locally.  The one thing I've noticed is that there is a lot of
inconsistency in how streets that cross divided roadways are named.

For example:
http://osm.org/go/Wpz_F8RFl-

Note Sunset Blvd on the left and Crystal Avenue on the right.
Crystal crosses all the way over to the left roadway.  As a result, going
south down the divided roadway, the Garmin picked up Crystal as the cross
street, when I think it probably should have picked up Sunset.

I'm thinking the solution would be to split the small way segment between
the major roads so that the naming can carry across the major roadway.

Make sense?

[Tagging] Relation for addresses far from the street

2010-05-01 Thread Tyler Gunn

I'm slowly filling in the local "mega-retail complex" near me:
http://www.openstreetmap.org/?lat=49.82432&lon=-97.20558&zoom=17&layers=B000FTF
Its a pretty large area, and there are a load of businesses and shops
within the area.  All of the roads in the area are for the commercial
development only; ie not named streets.  Thus all of the businesses have an
official address on the main road, "Kenaston Boulevard".
Take "Wok Box" for example; I've added all the addr: tags to indicate its
address.  I was about to create a relation for the address information
(http://wiki.openstreetmap.org/wiki/Proposed_features/House_numbers/Karlsruhe_Schema#Using_Relations_to_associate_house_and_street_.28optional.29)
but then got to wondering what I should associate the POIs to.  I mean
TECHNICALLY the street address is Kenaston Boulevard, but the POIs are
really so close to the service roads, I wonder if I should make the
relation to there?

Thanks!

In my area, sidewalks are most certainly NOT the norm.  There are very few
of them, and where they are present they are typically separated from the
road by a boulevard.  Other areas of my city have sidewalks that are right
up against the roads.  

I can see the merit of representing sidewalks that are right up against
the road by using an attribute on the road.  However for sidewalks
separated from the road by a boulevard I'd think it makes more sense to
draw them in as separate paths.

Just my 2c.

I guess it depends what you consider micromapping...

[Tagging] Parking for businesses..

2010-05-17 Thread Tyler Gunn

I was using the OSM maps for my city on my Garmin recently and when I
listed the "parking" POIs I noticed a whole slew of parking showing up in
there; mainly "unnamed"..  It got me thinking why those are in there but
then it dawned on me that in my area I've started adding in the parking
lots and service roads for businesses in my area:
http://www.openstreetmap.org/?lat=49.790516&lon=-97.156395&zoom=18&layers=B000FTF

This brought up a few questions:
1. What should the "access" for these parking lots be?  access=public
would seem to be appropriate, but in some regards that's not entirely
accurate.  Almost all of these types of parking lots will have some kind of
notice that tow-away is enforced for unauthorized parking.  So the general
idea is you're free to park there, ONLY if you're visiting the businesses
serviced by the lot.
So would access=permissive (The owner gives general permission for
access.) or access=destination (The public has right of access only if this
is the only road to your destination.) be more appropriate?
2. Should I bother naming these parking lots?

Thanks!

According to OSMDoc and Tagwatch there are a handful of access:customer
tags out there, and maybe 100 access:customers.  So it's clearly not an
accepted value yet.

I'd agree with the 3 values you proposed though; really access=customer is
the only new one.

Makes sense to me too because it allows for a true distinction between
general public parking (like multi-story parkades that are in the business
of parking cars regardless of where the people are going), and parking lots
intended to service the customers of a store, business, etc.

I like this; access=destination definitely holds the right meaning for
parking in front of a store as it is intended only for those whose
destination is that particular store.  I couldn't find any existing
relations to link things in this manner though.  

Does anyone know of any examples of parking lots tagged in a manner

How about something like:
access=private
permitted=patron/permit_holder/staff

There's probably other valid permitted types, but this organization would
handle the following types of situations quite well:
- Public parking lot (ie you come here and pay to park, regardless of
where you're going): access=permissive
- Store parking lot for customer: access=private, permitted=patron
- Store parking lot for staff only: access=private, permitted=staff
- Parking lot for monthly parkers: access=private, permitted=permit_holder

A relation to define what businesses are served by the lot could be
something like:
type=parking_use
Where you'd have member roles:
lot: a parking lot(s)
for_use_by: the business(es) that the parking is intended for.
I think in most circumstances it is probably pretty clear which business a
parking lot is intended for though.

I have to agree; the huge bonus with OSM is the level of detail that we
can achieve with it.  Also being able to start embedding not as obvious
knowledge into the mapping data is a huge plus.

Lol, now just think if we micro-mapped each tree in the parking lot you
could get your GPS to determine the spot that is likely to be in shade for
a large part of the day, keeping your car nice and cool! :)  Ok, too far
perhaps.

Or perhaps something like "permitted_parkers"; I don't think there's
anything wrong with a somewhat specific tag like that.  It'll prevent
ambiguity in the future such as what we're trying to resolve here with the
"access" one.  :)

Ooops, yes, you did.  Great idea! :)  So many emails, so little time.

Agreed; similar words to mean similar things.  I opted for patron rather
than customer so that it was a little more generic; it sounds a little
funny to say patient parking for a doctor is "customer parking".  :) 
Patron is a little more generic I think.

[Tagging] Tagging individual properties?

2010-08-19 Thread Tyler Gunn

I'm curious, what would be the best way to tag the boundaries of
individual properties?  Or SHOULD I even attempt this?
The Cadestral data for Manitoba is available from the Manitoba Lands
Initiative under a free for use license, so I was thinking of incorporating
this data.

I've converted a bit of the data, opting to merge all the lots into larger
blocks to indicate the landuse of residential, park, etc.  It's kinda nice
because it also gives you a guide for aligning the roads; they should
typically be in between the landuse areas. 

I think it looks pretty decent with the houses I added in from Yahoo:
http://www.openstreetmap.org/?lat=49.775024&lon=-97.170408&zoom=18&layers=M

However, in areas where there is no satellite imagery available to put in
the houses, I feel that NOT identifying the boundaries of each lot really
gives up on what could be valuable information; knowing the boundaries of
each lot would be a great navigational aid.
http://www.openstreetmap.org/?lat=49.78962&lon=-97.164207&zoom=18&layers=M

I tried just importing the data straight in where each lot was it's own
multipolygon (lots of shared boundaries) with landuse=residential.  However
when rendered in Mapnik and osmarenderer, it just came out as a solid
colored area with no indication where the lots are.  Perhaps I would need
to mark the ways some how?  Just trying to think how to get the data to
show up.  If it doesn't show up then my current approach of just marking
the landuse using this data is sufficient.  

Opinions?

That's a possibility.  Though I have no way to be sure where the fences
extend to in the front half of the properties.  Probably not worth it now

So far the data seems pretty accurate.  It's the IDENTICAL data that is on
the city's website, which lines up perfectly to the high resolution (<1m)
aerial imagery they have of the entire city.  When I brought it over into
OSM as large "landuse blobs", it straddles the existing OSM streets quite
nicely.

The railway lands and park boundaries are another great use of this data. 
Especially given how out of date the satellite imagery of my city is. :)

Yeah, the more I think of it, the less I want to use this to mark property
boundaries.  I think I'll stick with just deriving the landuse areas out of
it and be done with that.  It's still a great source of information in that
respect.

There's actually an inverted siphon here in Winnipeg.  It's used to allow
the Seine River to pass UNDER the red river floodway:

The meandering river in the middle of the frame seems to dissapear and
reappear in the middle of the frame. In reality the river flows into a
concrete box, under the floodway, and then comes up and out the other side.

[Tagging] Boundaries for suburbs

2011-02-24 Thread Tyler Gunn
What is the "proper" way to tag a boundary for a suburb?  I'm trying to avoid 
using "place=suburb" nodes as they don't accurately capture the boundaries of 
the neighbourhoods I'm attempting to map.

I've been playing around with this in my area and came up with two examples:

Example One:
- "place=suburb" node central to neighborhood:  
http://www.openstreetmap.org/browse/node/1168219909
- Boundary relation with the the "place" node marked as a label: 
http://www.openstreetmap.org/browse/relation/1438874; included the place 
attributes on the boundary as well.  Not sure if required.

An example of how I've attempted this is as follows.  At this zoom level, 
Mapnik correctly renders a label for the suburb, 
http://www.openstreetmap.org/?lat=49.80617&lon=-97.18193&zoom=16&layers=M
Zooming in once more reveals TWO labels for the area:
http://www.openstreetmap.org/?lat=49.80617&lon=-97.18193&zoom=17&layers=M
See above links for the node and relation in my example.
It's clear that when you zoom in the larger label is from the place node, and 
the smaller one is from the boundary itself.
Mapnik seems to render appropriately.

Example Two:
Another attempt I made used the scheme:
- "label" node central to the neighborhood: 
http://www.openstreetmap.org/browse/node/499644122
- Boundary relation with just administrative level stuff in it: 
http://www.openstreetmap.org/browse/relation/1438875
Here you can see that the neighborhood label renders much smaller
http://www.openstreetmap.org/?lat=49.81031&lon=-97.16204&zoom=15&layers=M 


I'm inclined to think that example Two is more correct, but I have to say I 
like the larger more prominent labels of Example One.  I know, probably not 
good to map for the renderer.

Opinions are appreciated!

THanks!

These are civic recognized sub-areas and neighbourhoods of my city, often times 
with varying land uses within.  I don't think the landuse=* is appropriate.  I 
see how the example you're shown works though; I can just see it getting ugly 
as you can't characterize the landuse of an entire section of the city as one.

So it would seem the place node itself is redundant then.  It should just be 
used as a label.

Perhaps I'll have to download and install Nominatim to see how it handles 
things too.  
Ultimately for display purposes it's one thing, but I'd like these 
relations/boundaries to be useful and unambiguous when it comes to determining 
where a particular location is.

Re: [Tagging] Feature Proposal - RFC - daycare

2011-04-21 Thread Tyler Gunn
You say: "A place for children to do homework, play and spend time
otherwise after school."
The "after school" part is inaccurate as day care centers are often a
place children go to during the day while their parents work.

Some other considerations:
- Type:
  - centers: larger in size, with multiple employees caring for a
larger number of children.
  - home-based: an individual watching children in their own home.
- Frequency of care offered: Full-time (ie children attend every day
on fixed schedule), part-time (ie less than full-time), before and
after school (as a service to working parents whom leave for work and
arrive home from work before and after the regular public school day)
- The existing opening_hours tag is useful information that someone
could specify for a daycare.
- Age ranges are important (ie some care for only school age children,
where others specialize in pre-school, infants, etc).
