I'm trying to get WKT or GeoJson polygons of cities and countries from Nominatim (for example, Paris and France). I send a GET
request but it returns me several results named "Paris" or "France". How may I narrow results only to a capital and a country. Here's my request url:
http://nominatim.openstreetmap.org/search/fr/paris?format=json&polygon_geojson=1
And I get an array of 10 objects where only one is the capital:
class: "boundary", type: "administrative".
The rest are:
class: "place", type: "isolated_dwelling"
class: "place", type: "hamlet",
class: "place", type: "neighbourhood"
and so on...
How to select only the desired city and only the desired country ignoring rest of results with the same name?
