Find centerpoint of polygon in JavaScript

Question

I have a \"place\" object from Google Maps which has a set of coordinates that represent a bounding box for a given location, say London. Each set of coordinates has a latit

Answer 1

To get the bounds of a Polygon (with your data) in the Google Maps API v3 (not tested):

var coords = [
  [ -1.2, 5.1 ],
  [ -1.3, 5.2 ],
  [ -1.8, 5.9 ],
  [ -1.9, 5.8 ]
];

var bounds = new google.maps.LatLngBounds();
for (var i = 0; i

var coords = [
  [-1.2, 5.1],
  [-1.3, 5.2],
  [-1.8, 5.9],
  [-1.9, 5.8]
];

var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < coords.length; i++) {
  bounds.extend(new google.maps.LatLng(coords[i][0], coords[i][1]));
}
var center = bounds.getCenter();

var latitude = center.lat();
console.log("latitude=" + latitude);
var longitude = center.lng();
console.log("longitude=" + longitude);
var coordinates = center.toUrlValue();
console.log("coordinates=" + coordinates);
