[Tagging] playground tag proposal

2010-04-20 Thread antony.king
Hi all,

re http://wiki.openstreetmap.org/wiki/Proposed_features/Playground_Equipment

I'd like to get this proposal finalized fairly soon as it has been
open for a month now. There has been a lot of useful discussion
already which I have taken on board and put into the main page.

Could I ask you all to take one more look at it; if there are any
points that would stop you voting for it in its current form them
please suggest improvements on the discussion page or on the mailing
list.

I'd like to get voting underway this weekend if possible, depending of
course on what issues are raised.

Many thanks for your help with this so far!

Antony.

Have you used this tagging scheme much to date?

Did you notice any issues?

I've been using it on my local playgrounds in kemsley, and minophos
has been using it on some in the Leighton Buzzard area and so far, the
only issue we've met is that we've had to add a few more equipment
types. I've also written an export tool so that you can view the
playgrounds on a UK map with some summary data; it's a bit ropey at
the moment (running on a Lex Light in my son's room!) but if you look
here:

http://ant.homelinux.net/maps

with username map, password mrmappy

you'll see a map of them; the blue ones are done according to the new
schema. If you don't see the icons, try again later; I'm hacking at it
right now.

I've also got mapnik somewhere nearby configured to draw the
playgrounds, which looks cool but I can't sensibly run it on my home
server.

too difficult to find the bit we should zoom into Anthony, so how about a 
screenshot?

It's in the bottom right corner, where the differently coloured icons are.

Have a look here for screen shots:

Overview of kent showing various playgrounds with one having been clicked on:

Detail of one particular playground rendered with mapnik on my server:

Hope that helps. There's also a facebook group for chatting about
accessible playgrounds in general - there's a link to it on the top of
http://ant.homelinux.net/maps .

the only one in my area has a liberty swing which takes an entire wheelchair 
and user

so it needs adding to the list
if you need a CC photo I'll have to arrange to photograph it

[Tagging] Entrances..

2010-04-20 Thread Erik Johansson
Wouldn't it be great if railway=subway_entrance was rendering, and if
we had a generic scheme to tag entrances for different stuff. I've
used building=entrance, but I need to tag railway=station_entrance,
train=door, highway=bus_station_entrance  etc. etc. How do I solve
this in a better way?

http://wiki.openstreetmap.org/wiki/Tag:railway%3Dsubway_entrance
http://wiki.openstreetmap.org/wiki/Tag:building=entrance
http://wiki.openstreetmap.org/wiki/Proposed_features/Stop_Area


When rendering railway=subway_entrance do you think one should disable
to rendering of railway=station, and in that case how do you know
which subway station to disable. About 1/3 of subway_entrances have
names, even fewer have relations, I believe using names has
advantages.

+1

currently I'm mapping them with barrier=wall (U-form) and
highway=steps in the middle (and on the end subway_entrance) but it
would be nice to have them show up.

you could use barrier=entrace, but this is according to my reading of
the wiki a hole in the barrier without door or gate, that's why I
usually use barrier=gate for general entrances (which do have a
door/gate).

-1, depends on the zoom-level


>, and in that case how do you know
> which subway station to disable.


name? proximity? That would get some false positives (double-stations)

> About 1/3 of subway_entrances have

well, but name is for the name of the feature, so it could well happen
that a subway entrance has it's own name that is not the one of the
station but the one of the street it is leading to.
I'd opt for the relation.

cheers,
Martin

Excellent work. For most of the recorded playgrounds in my area I have recorded 
the information of what equipment exists in order to save a re-visit. Hopefully 
with this that data will actually be worthwhile.

Cool - if you tag up those playgrounds do let me know as I could do
with some more test cases for my renderer etc. Also if you hit any
snags with the schema it would be good to get them ironed out sooner
rather than later.

Thanks for the encouragement!

Re: [Tagging] [OSM-newbies] motorway _link and _junction tagging

Yet another subject I've been wanting to write/ask about. Sorry if I should 
have put this in the wiki instead of the list, but I figured we can hash it 
out here before I move it there. I realize it's long. :) It might also be 
better discussed in tagging and then noted back in newbies once it gets 
agreed on? I've therefore Ccd tagging.

Here's the approach I've been using in the LA area. It's gone through a few 
iterations, and so may not be completely consistent.

Examples:

Motorway/street interchange: 
http://www.openstreetmap.org/?lat=34.13614&lon=-117.53647&zoom=17&layers=B000FTF

and motorway/motorway interchange: 
http://www.openstreetmap.org/?lat=34.13521&lon=-117.49705&zoom=16&layers=B000FTF

The information in the tags, though appearing to be free-form, is actually 
formulaic (when I don't make mistakes :) ). Ideally, I'd like to create 
separate tags for the components, or use some other structured solution, 
but I started doing it as a newbie, and just wanted to get on with 
processing my surveys without going 12 rounds with the mailing list on the 
correct structure. All the info is present, and I'm ready to massage it 
into whatever schema is agreed upon.

Here's what I've been doing.

*
Onramps:

JOSM preset [0]:


 

 
 
 

 
 
 

 


Tags:

- name: "  onramp" e.g. "CA-210 West onramp" [1].
- ref: "from [ ]" e.g. "from Rosemead Blvd North". 
 is added only when the ramp is accessible from only one 
direction of travel on the street where the ramp originates [2]. When a 
ramp starts on a side street, this may instead look like "from Francisquito 
Ave via Garvey Ave", where the ramp is known as the Francisquito Ave ramp.


*
Exit node (where offramp joins motorway):

JOSM preset:


 
 

 
 
 

 
 
 

 
 
 
 
 
 
 


Tags:

- name: "[ ][ ]" e.g. "Azusa Ave North - San 
Gabriel Canyon". The name as official/signed.  is present if it 
is only possible to go in that direction when reaching the target street.
- ref: "Exit " e.g. "Exit 23A". The official/signed exit 
number. Note that various states in the US are at different stages of the 
signage installation - it may be necessary to get them from the state DOT's 
docs (that's the "CDOT" in my source tags).
- optional items come from the California DOT. I was originally typing them 
in as I processed each exit, but stopped doing this in favor of doing an 
import when I get around to it.


*
Exit ramp:

JOSM preset:


 

 
 
 

 
 
 

 




Tags:

- name: " offramp" e.g. "Azusa Ave North - San Gabriel 
Canyon offramp". Take the name tag's value from the related Exit node and 
add " offramp".
- ref: " from  " e.g. "Exit 23A from 
I-10 East"


*
Final thoughts:

With motorway interchanges (with other motorways), I treat the connectors 
as onramps - the  role being the originating motorway and the 
 role being the destination motorway.

Sometimes, my connector and onramp names look like "  
/  onramp" e.g. "CA-210 East / Redlands onramp".  is the 
signed (actually official in CA) destination of the motorway, or a major 
city along the way [3].

When a link is shared by traffic both exiting and entering the motorway, I 
use a semi-colon-separated list of values. Example:

name="I-710 South - Long Beach onramp;I-405 North - Santa Monica onramp"
ref="Exit 32B from I-405 North;Exit 4 from I-710 North"

for this way: http://www.openstreetmap.org/browse/way/26968059

The same applies to the situation where one exit ramp for both destination 
directions leaves the originating motorway and then splits into separate 
links (see freeway interchange example at top). I see, in that example, I 
put both directions in the name key instead of using the semi-colon 
approach - something I'll have to deal with manually.

Admittedly, much of what is tagged to the ramps can be derived from the 
related nodes at each end with some work. There just didn't seem to be 
anyone doing that work, so I wanted to be able to have them make sense when 
rendered/spoken now, particularly when used by routing.

Notes:

[0] About presets:
- I also add '' to my presets, based on 
the wiki saying this tag has been deprecated, and can be removed when seen.
- For the onramp/offramp way presets, I also add '' because there was some conflicting info in the wiki as to 
whether this was implied for *_link ways.
