I want to create a map with openlayers, that contains a vector layer, with all "counties" of all countries of the world. "County" doesn't mean any strict political term here. I just want to split the earth into areas of ~500 - ~2500 km2 (or even much larger in sparsely populated areas), while these areas should have names, that are common to the people living there.
Now I'm searching data sources.
- The data should be free
- Each county information should contain the name in one of the languages spoken in this county.
- It is not important, that the borders are exact - it is just used for a visual selection of some counties, the user wants to do something with
- It must be complete for each country, that is available (no areas without a "county").
- For now, it would fit to have those data available for Germany, Austria and Switzerland, but it would be fine to find a solution, that would allow us, to add other countries without having another data import and maintainance workflow for each country.
