How to export all countries boundary from OSM to either Shape File or KML format?

Question

I am trying to extract the whole world from OSM on the basis of administrative level (i.e, admin_level=2) using overpass turbo but it is difficult as it doesn't allow to download whole world at a single time. So please help me if you have any idea to export only countries boundary.

Accepted Answer

You can download the OSM planet file and filter out the admin boundaries (see this answer for example), or you could download from the boundaries map.

However, if you only want country boundaries then my suspicion is that you do not need the full detail that OSM offers (OSM data follows every smallest zig-zag of the boundary, resulting in very large polygons), and you might also dislike the fact the OSM boundaries don't hug the coastline but include the maritime claims as well. It might be much easier for you to head over to the public domain Natural Earth dataset which comes simplified for three different scales.

Here is the curl command to download the countries border

curl \
  --connect-timeout 10  \
  --retry 10  \
  --retry-delay 10  \
  --retry-max-time 500  \
  -H "Host: overpass-api.de" -H "Content-Type: text/xml"  \
  -d 'relation["admin_level"="2"];(._;>;); out body;'  \
  http://overpass-api.de/api/interpreter  \
  -o countries-border.osm

And use ogr2ogr to convert osm to shapefile.
