如何通过 OverPass API 获取父级管理边界

Question

具有一定级别的行政边界关系，如何获得父级别边界的最佳方式？

这适用于布拉迪斯拉发市 Petržalka 部分： http://overpass-turbo.eu/s/ewU

[out:csv(::id,::type,"name","admin_level")];
rel(2208781);
(._;<<;);
out;

结果是：

@id     @type       name                    admin_level
14296   relation    Slovensko               2
388210  relation    okres Bratislava V      8
388265  relation    Bratislavský kraj       4
1702499 relation    Bratislava              6
2208781 relation    Petržalka               9

但它不适用于维也纳部分 Meidling http://overpass-turbo.eu/s/ex1

[out:csv(::id,::type,"name","admin_level")];
rel(1990596);
(._;<<;);
out;

结果

@id     @type       name        admin_level
1990596 relation    Meidling    9

显然，问题在于维也纳边界关系中没有定义子关系。有什么靠谱的办法可以找到这些亲子关系吗？

Answer 1

再次搜索附近然后向下

它还不是完美的，因为我仍然不知道如何进行递归查询。

1. 搜索附近的更高行政部门。 （对于附近的城镇来说5公里似乎不错）

   [out:csv(::id,::type,"name","admin_level")];
   rel(id:1990596);
   relation["admin_level"~"8|7|6|5|4"](around:5000);
   (._;<<;);
   out;
   

   @id   @type   name    admin_level
   16239 relation    Österreich  2
   77189 relation    Niederösterreich    4
   109166    relation    Wien    4
   111858    relation    Bezirk Mödling  6
   111881    relation    Gemeinde Hennersdorf    8
   111887    relation    Gemeinde Breitenfurt bei Wien   8
   111946    relation    Gemeinde Perchtoldsdorf 8
   111948    relation    Brunn am Gebirge    8
   111956    relation    Gemeinde Vösendorf  8
   2668952   relation    European Union / Union Européenne / Europäische Union   
   12729625  relation    Eurozone / Zone euro    
   13376469  relation    Member States of the European Union / États members de l'Union européenne / Mitgliedstaaten der Europäischen Union
   

2. 寻找每个内部的下级行政人员进行验证

   [out:csv(::id,::type,"name","admin_level")];
   area["name"="Wien"]["admin_level"="4"]->.target_area;
   relation["admin_level"~"9|8|7|6|5"](area.target_area);
   (._;<<;);
   out;
   

   @id   @type   name    admin_level
   1990590   relation    Alsergrund  9
   1990591   relation    Hietzing    9
   1990592   relation    Innere Stadt    9
   1990593   relation    Josefstadt  9
   1990594   relation    Leopoldstadt    9
   1990595   relation    Mariahilf   9
   1990596   relation    Meidling    9
   1990597   relation    Neubau  9
   1990598   relation    Penzing 9
   1990599   relation    Rudolfsheim-Fünfhaus    9
   1990600   relation    Währing 9
   1991416   relation    Landstraße  9
   1991433   relation    Brigittenau 9
   1991434   relation    Donaustadt  9
   1991435   relation    Döbling 9
   1991436   relation    Favoriten   9
   1991437   relation    Floridsdorf 9
   1991438   relation    Hernals 9
   1991439   relation    Liesing 9
   1991440   relation    Margareten  9
   1991441   relation    Ottakring   9
   1991442   relation    Simmering   9
   1991443   relation    Wieden  9
   3980995   relation    Amtshaus für den 16. Bezirk 9
   

长期解决方案

最好的仍然是直接回馈并更新父关系。不需要太长时间，维基数据/维基百科已经公开了此类信息。或者至少在 Meidling 上提交 OSM“注释”，以便有知识的人可以修复它。
