HTML5 gives you the ability to capture the geolocation information from the browser of your visitor. They will be prompted to allow the access, but after they grant it – the information shown below will become available to your JavaScript application.

Your Geolocation Data:

JavaScript:

function GeoSuccess(position) {
  var latitude = position.coords.latitude;
  var longitude = position.coords.longitude;
  var accuracy = position.coords.accuracy
  var altitude = position.coords.altitude;
  var altitudeAccuracy = position.coords.altitudeAccuracy;
  var heading = position.coords.heading;
  var speed = position.coords.speed;
 	document.getElementById('pre').innerHTML = "Latitude: "+latitude+"<br />Longitude: "+longitude+"<br />Accuracy: "+accuracy+"<br />Altitude: "+altitude+"<br />AltitudeAccuracy: "+altitudeAccuracy+"<br />Heading: "+heading+"<br />Speed: "+speed; 
}
function error(msg) {
  error('There was an error pulling your location');
}
if (navigator.geolocation) {
  navigator.geolocation.getCurrentPosition(GeoSuccess, error);
} else {
  error('Geolocation not supported');
}
