Simplified OpenStreetMap boundaries download
These packages contain shapefiles in web mercator (EPSG:3857) projection intended for use in web maps at zoom levels 2-8. They have been produced exclusively from OpenStreetMap data. The maritime boundaries are only included where they are necessary to indicate what country a certain island belongs to.
|admin_level 2 boundaries for z=4||admin_level 2+4 boundaries for z=6|
The exact degree of simplification used for showing boundaries depends on the style of a map so you might need to use these files with an offset in zoom levels.
These files are made available under the Creative Commons Attribution-ShareAlike 4.0 license. Data source is © OpenStreetMap contributors. Some might wonder why these are not licensed under ODBL like the original OSM data - this is because the simplified boundaries are a rendering of the data and it is neither intended nor possible to extract the actual boundary data from it. Therefore it is a produced work in terms of the ODBL.
