Re: [OSM-talk-be] SOTM-EU

SOTM-EU 2014 is over but all the sessions were recorded, yay!

https://www.youtube.com/user/sotmeu

Jorieke gave a talk of all the great work she helped with in Lubumbashi,
Congo:

As a good Dutch speaking Belgian she went to Germany to present in English
with French slides :-)

Her talk starts around 37 minutes.



The talk I liked a lot as well is the one from Roland Olbricht, who
developed the Overpass API, which I saw this morning on the live stream. It
will probably be put online soon as well.

He continued development of Overpass and now it's possible to make queries
which dig into the history of the OSM objects.

So it's possible to compare between 2 points in time, which is not entirely
trivial, as normally our ways and relations don't have geodata included.
(Only nodes do), but he found a way to accomplish it.

Enjoy!

Jo, who feels sad he didn't go, but who's glad to 'have been there'
virtually thanks to amazing internet technology.

 Hi All!

 It's only 7 weeks until SOTM-EU (http://sotm-eu.org/) and I want to
 advertise a little and hope some of our Belgian-mappers are going to join!

 *Where?*

 SOTM-EU is in Karlsruhe this year so not far at all!

 http://osrm.at/7cW

 *When?*

 13-15th june

 *Who's going?*

 Me  Jorieke will be there but you will meet a lot of other mappers and
 maybe finally will have some faces with all these names/emailadresses.

 *What usually happens at SOTM and why we go:*

 - You will meet a lot of fellow mappers but also get the opportunity to
 learn more about OSM and what is happening in the wider OSM-community.
 There are always new things going on and you will be amazed at how crazy
 people can be about what they are doing (in a good way ;-)).

 - On Friday and Saturday there are talks about mapping/tools/community...
 and on Sunday there is a 'Hack Day', you can join a local mapping party or
 join one of the workshops.

 - I have never been to a SOTM and regretted it afterwards... ;-)

 - This is a great opportunity to join because SOTM-EU is right around the
 corner and it's completely uncertain what will happen next year.

 - And last but not least, the informal part of the weekend: usually there
 is a pub-delegation with a lot of talking and drinking happening.

 *How can you get there?*

 If some of you are interested let us know, we will probably drive there
 and we can take on at least two extra passengers! We can pick you up
 somewhere, at least you will get there for free... :-)

 According to your schedule we can discuss when we leave/come back.

 It would be nice to have a some new faces from Belgium there this year!

 Met vriendelijke groeten,
 Best regards,

 Ben Abelshausen

At the moment it's only fully reliable since the beginning of June 2014.
Somewhere in July he will have replayed the whole history once more.

 As far as I know (from his blog I believe), it's only since 2012. he needs
 the time to rerun all planet updates from the beginning in order to have
 all history.

Re: [OSM-talk-be] TEC Open Data: let's start !

2014-06-15 Per discussione André Pirard

Hi,

I'm conducting an offline TEC conversation business with Jo and I'm
impressed.
You will soon be able to confidently buy TEC tickets and use the OSM
transport map ;-)

I have just two tag remarks.

For the third time (Julien), if we want to use URLs, we'd better use URLs.
network=tec-wl.be is not an URL as you can see by not being able to
click on it here http://www.openstreetmap.org/node/857875464.
network=http://tec-wl.be is one as you can see by being able to click on
it here http://www.openstreetmap.org/node/1645537259.

I recommend adding *source=survey 2014-06 TEC 2014-04*
Much like Key:source http://wiki.openstreetmap.org/wiki/Key:source
indicates and I am presently proposing to amend slightly as shown below.

The bulk import scenario was clearly written with in mind the idea to
maintain a remaining-to do TEC file.

Suppose an *.osm file is built from an imported source. The map
contributors are requested to move/update the map elements to osm.org
after verifications such as coordinates. If the *.osm map elements
contain a survey value such as source=survey import-date, then a
program can find out by checking for an equal or later survey date what
map elements have been moved/updated to osm.org and hence build a
remaining.osm file containing what remains to be done. A FIXME can be
added at import time to already existing osm.org elements to warn about
the ongoing import.

Cheers,

André.

Following this discussion here is a proposed clarification to
Key:source http://wiki.openstreetmap.org/wiki/Key:source.
The goal is to define the word, make date mandatory, use ISO format,
define per source tag meaning.
Is there any objection or suggestion for changes?

*survey* -mm[-dd] (with one blank and an /ISO/ 8601
http://www.google.be/url?sa=trct=jq=esrc=ssource=webcd=3cad=rjauact=8sqi=2ved=0CDAQFjACurl=http%3A%2F%2Fwww.iso.org%2Fiso%2Ffr%2Fhome%2Fstandards%2Fiso8601.htmei=X3qZU_CEPNHR4QT34YGwCgusg=AFQjCNHMm5_cA8CzTjEvrWYQc5GZ9K1wLgsig2=m6xdSXuaBGqt6Qlj0tCfTwbvm=bv.68911936,d.bGE
format date) can be used within the data of any source.KEY=* or
source=* tag to indicate that, on that date, the source(s) of KEY were
the most recent and the data was verified to be correct for that KEY.
In source=*, survey means the same for all possible (required) keys
(even those absent by default), but it can be overridden by survey in
some source.KEY tags. survey helps to avoid making already done
verifications, especially because a source publication date is not a
verification date. survey can contain the date of dateless sources
like visual or knowledge. It can help humanly assisted bulk imports.
Please update the survey date of what you verify (a substantial time
later), even if you don't add survey dates yourself.
