Re: [OSM-talk] 5th Sep. Akihabara mapping party, Tokyo

[Daniel Kastl]

Higashi-san,

Very cool place for a mapping party!
If you're in Tokyo and have a time, I definitely recommend you to join.

I will add this also to the SotM website.

We're planning to record the presentations, so you can watch them live, if
you like.
Details will be posted on the SotM website: http://www.stateofthemap.org/

[OSM-talk] SotM live streaming

[Daniel Kastl]

In a few minutes the SotM 2012 in Tokyo will start:
http://www.stateofthemap.org/

As every year for the majority of mappers it's not possible to attend the
yearly OpenStreetMap conference.
But for everyone, who couldn't come to Tokyo we offer to watch the talks
and presentations live on Ustream.
There are two channels:

   - Main: Convention Hall (2F)
   http://www.ustream.tv/channel/sotm-main

   - Second: Conference Room (3F)
   http://www.ustream.tv/channel/sotm-second

For the program schedule take a look here:
http://www.stateofthemap.org/schedule/
(Tokyo is 9 hours ahead of UTC)

Slides and other material will be collected and published in the conference
Wiki:
http://wiki.openstreetmap.org/wiki/State_Of_The_Map_2012/Thursday
http://wiki.openstreetmap.org/wiki/State_Of_The_Map_2012/Friday

OSMF Japan (the local Japanese chapter) has already contacted the writer as

update/correction of the statement.

Anyway, it's just a matter of time until OSM will be the reference map in
Japan. We're working on it ;-)

The difference in their proprietary system (if you want to call
address systems in in countries closed and proprietary) is, that when
their API (and "algorithm") goes away, you won't find any address
anymore. It's totally unreliable to depend on a proprietary API to
locate an address, and a waste of time to add such data to OSM in my
opinion.

Daniel

Hi Colin,

Beside the different opinions about proprietary and closed technology,
what is the point to add these 3 words as a tag? I don't really
understand the benefit, because the relation between location
(coordinates) and their address system is fixed. It's just a 3x3m grid.

In OSM every object has a geometry and you can query the w3w address
just using their API. So I don't see the point where it makes sense to
add such an address tag. It's like you add "latlon" as a tag.

Regards,
Daniel

Not only India, also other countries such as Japan have a block address
system, which for example doesn't match with how openaddresses collects data
at the moment.
Here some good explanation: http://sivers.org/jadr

Such a block address system actually has some advantages as well. You don't
have to know the house number to be able to know about where the address is
located. You can take the center point of the block polygon as well and it
will usually be a good approach. With long streets this is usually not
possible.

Re: [OSM-talk] Crisis mapping - assistance requested for infrastructure mapping in Tohoku/Japan

[Daniel Kastl]

I heard from several foreigners, that one problem to help is that they often
can't read what's written on Japanese websites.
Some convenient tool, that is easy to install as extension for Chrome is
called "rikaikun":
https://chrome.google.com/extensions/detail/jipdnfibhldikgcjhfnomkfpcebammhp

It helps a lot to translate city names for example or small paragraphs,
probably not complete websites (and no flash and images).

Otherwise don't hesitate to ask in English on the OSM talk-ja mailing list
or in IRC (irc.oftc.net #sinsai-info).
Even if the people there mainly use Japanese, there will be someone
to answer your questions or help with translations.

Hi Jan,

How did you count them? Which tags?
In Japan so called "convenience stores" are almost everywhere.
Though I think not a lot of shops and other buildings have been mapped in
Japan before.

Re: [OSM-talk] Fwd: Traffic simulation Modeling using OSM data

[Daniel Kastl]

Hi Sourav Dutta,

Your GSoC idea might eventually fit to the pgRouting project (
http://www.pgrouting.org/), which also participates in GSoC as part of
OSGeo as a mentoring organization:
http://wiki.osgeo.org/wiki/OpenRouter_2012_SOC_Ideas

pgRouting had one GSoC project last year implementing time-dependent
shortest path algorithm. An algorithm that takes into account the network
condition at the time it reaches a link in the network. The library is not
only about routing but open to any kind of network analysis, like  flow
algorithms would be something I'd like to see.

As Graham said, your proposal has only a small OSM part. But of course you
can make use of OSM data for a reference implementation.
More general information about OSGeo and GSoC you can find here:
http://wiki.osgeo.org/wiki/Google_Summer_of_Code_2012

Re: [OSM-talk] Transcription and "internationalization" in place names

[Daniel Kastl]

I think Japanese names are a good example how complex name tags can be, see:
http://wiki.openstreetmap.org/wiki/Japan_tagging#Names

There are altogether listed 5 tags for a name: name:ja_rm or name:en are
what you can read without knowing Japanese characters.
name:ja_rm is probably what will not be rendered usually, but this would be
the name written for example on street signs as name in latin characters.
name:ja_kana is what was mentioned in a previous email, because it helps
Japanese people to know the reading of a name. It's also useful for
geocoding.
