How to determine which country/ state/ region/ city/ locality lies inside a leaflet polygon | rectangle | circle etc

Question

How can I determine which country, state, region, city or locality lies inside a leaflet shape (polygon | rectangle | circle etc) created by the user?

Answer 1

I think you are looking for Reverse gecoding. Leaflet does not provide gecoding services,but you can find similar example here.

Google Geocoding service provide results in JSON format but you may need to pay for extra quotas.

Sample link: http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452

Updated with Stack Snippet:

window.cb = function cb(json) {
  document.getElementById('result').innerHTML = 'Country:' + json.address.country + '|' + 'State:' + json.address.state + '|' + 'County:' + json.address.county + '|' + 'City:' + json.address.city;
}

window.getLocation = function getLocation() {
  var s = document.createElement('script');
  s.src = 'http://nominatim.openstreetmap.org/reverse?json_callback=cb&format=json&lat=40.714224&lon=-73.961452&zoom=27&addressdetails=1';
  document.getElementsByTagName('head')[0].appendChild(s);

};

.myText {font-weight:bold;font-size:1.0em;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button onclick="getLocation();" name="search" class='myText'>Get Location!</button>
<p id="result" class='myText'></p>
