I want to get the polyline's coordinates without any extra info from a relation like this one:

[[40.54,40.65],[40.55,40.64]...]

Here are some relations for which I need this data: 29322, 19782, 19763

How can I do it? I tried to use overpass turbo but it gives me ways and nodes which is not what I want.

Overpass Turbo also lets you export GeoJSON which comes very close to what you are looking for.

Overpas turbo gives me multiple arrays and the polyline is broken for some reason. https://i.imgur.com/2VNyWBe.png The red line should be following the black markers. Also here the line is fine but only for the one direction. On the other it gets wiggly. https://i.imgur.com/d1fznCF.png

I tried an Overpass query like relation(19763); out geom; and loaded that in geojson.io and it looks all right...

It looks like something went wrong when I saved the data to the database which caused the problem.

edit: It doesn't work for relation 19777. Overpass Turbo returns multilinestring instead of linestring which breaks something. How can I convert multilinestring to linestring?

edit 2: This query fixed everything:

[out:json][timeout:300];

(

relation(relation_id);

<;

);

out geom;
