Overpass API: Is it possible to select polygon and get geographical data?

Thanks in advance!

I want to select polygon and get geographical data of polygon's edges, like polyline.

Do you mean you want to download all data inside a non-rectangular polygon? That is explained on .

  node(poly:"50.7 7.1 50.7 7.12 50.71 7.11");
out meta;

Note that you need some kind of recurse magic to also get ways and relations.

To get bounding box coordinates by selecting from a map use (german; you need to hold down ctrl and then click and drag the bbox, the coordinates will be displayed in the bottom text fields).

To download by country, use area[name="Belgium"];( node(area); <;);out meta;. The precise name can be tricky, but you can open [the popup UI][1], click somewhere in your country and search on the last pages of the popup for an entry with "Country Boundary". That gives you the OSM name of your country to use in the above query.

Can I do it by selecting name of country and how?

If you are looking for country outlines, go to and download their "admin0" data set.

If you want to do the mentioned query via overpassapi limited by the outline of a country, go to and enter the countries name ... examine the results carefully and find the right relation within the raw OSM data.

Then you can decide to use the relation ID number that you can use by adding the mentioned offset, or type the name of the "area" that you have found.

But be sure to use the right name, and that the name is unique in the OSM database.
