How to get LatLngBounds of feature polygon geometry in google maps v3?

Question

I have a lot of polygonal features loaded with loadGeoJson and I\'d like to get the latLngBounds of each. Do I need to write a function that iterates through every lat long

Answer 1

Here's another solution for v3 Polygon :

var bounds = new google.maps.LatLngBounds();

map.data.forEach(function(feature){
  if(feature.getGeometry().getType() === 'Polygon'){
    feature.getGeometry().forEachLatLng(function(latlng){
      bounds.extend(latlng);
    });
  }
});
