[OSM-talk] Es weihnachtet wieder sehr ....

2013-11-08 Thread Jan Tappenbeck

Hoho !

in den letzten Tagen habe ich schon einige Anfragen bekommen - jetzt ist 
es wieder soweit die OSM XMAS-Karte [1] wird wieder aktuallisiert und es 
können die Daten wieder fleißig nachgeführt werden.


Für die Neueinsteiger finden sich die Tag-Beschreibungen unter [2].

Ich möchte auch nochmal auf die Auswerte-Liste oben Links verweisen um 
zu sehen welche Daten nachgeführt werden müssen.


Leider bedarf es bei der Karte immer noch eine manuelle Nachführung - 
eine real-time-Abfrage über die Overpass-Api gibt es noch nicht - der 
Grund hierfür sind erforderliche Berechnungen für die 
flächenrepräsentiven POI. Die habe ich zum einen nicht und weis auch 
nicht wie das umzusetzen ist.


Viel Spaß damit.

Gruß Jan :-)

Please, don't tag events in OSM. We don't delete roads when they are
closed for one month. So don't add a christmass tree because it's
there for 3 weeks. Add buildings and/or market places as much as you
want but use apps like umap ([1]) for event map mashups.
I deleted the 6 or 7 of your "xmas:feature" I found in France (mainly
contributed by Germans), all coming from last year and, of course,
never maintained (e.g. obsolete opening dates).

BTW, wrong list !

Christmas trees are not an "event". They are built up on mostly the same spot
every year (at least here in Vienna) and it of course makes sense to map them.

I regret you delete features without having verified if they are current or not.

If you like. Call it "temporary feature", like tents in camping,
exhibitions, motor shows, food trucks, etc

Good point. Since it is not "verifiable" 92% of the time, it has
nothing to do in OSM.

Re: [OSM-talk] Overpass area query gives results outside area...

I need to extract objects that fall within the bounds of Senegal - so I

As an exercise, let's find Dakar in Senegal - http://overpass-turbo.eu/s/1qa 
:


   area[name="Senegal"];
   (area
   [name="Dakar"]
   (area);
<;
   );
   out;


  area[name="Senegal"];
  node(area)[name="Dakar"];
  out;

returns a place=city, place=state and a container harbour, but not Dakar 
in San Sebastián.

Yes, my syntax was incorrect.

To return multiple types of objects, this works:

area[name="Senegal"];
(
  node(area)[name="Fatick"];<;
  way(area)[name="Fatick"];<;
  rel(area)[name="Fatick"];<;
  area(area)[name="Fatick"];<;
);
out;

I would expect the area() to be a subset of way() and rel(), so you 
wouldn't need to add it to the query?

That is also what I thought... But somehow it is not the case - closed
ways are treated differently.
