    類別 Geolocation

    Helper class for providing HTML5 Geolocation capabilities. The Geolocation API is used to locate a user's position.

    To get notified of position changes, register a listener for the generic change event on your instance of ol.Geolocation.

    Example:

    var geolocation = new ol.Geolocation({
  // take the projection to use from the map's view
  projection: view.getProjection()
});
// listen to changes in position
geolocation.on('change', function(evt) {
  window.console.log(geolocation.getPosition());
});
