openstreetmap - 从高速公路中提取节点

Question

我正在使用立交桥涡轮从高速公路（=高速公路）中提取节点。下面是我正在使用的代码。但是，此代码为我提供了边界框中的所有节点，并且没有过滤高速公路。

[out:xml];
(
(way(39.90,32.83,39.96,32.89);)->.a;
((way.a["highway"="motorway"]);)->.b;
((way.a["highway"="motorway_link"]);)->.b;
);
(.b;>;);
out body qt;

Answer 1

请参阅我在 help.osm.org 上发布的答案：https ://help.openstreetmap.org/questions/41754/extracting-node-from-highways

Answer 2

Try this query instead:

[out:xml]
[timeout:25]
;
(
  way
    ["highway"="motorway"]
    (39.90,32.83,39.96,32.89);
  way
    ["highway"="motorway_link"]
    (39.90,32.83,39.96,32.89);
);
out body;
>;
out skel qt;

You can view it on overpass turbo. Note that it doesn't return any results because the given bounding box doesn't contain motorways. Either increase the bounding box size or choose a different highway value, for example highway=primary.
