location detection in web browser [closed]

I am searching for a method to locate the user location while visiting my website, i have tried Maxmind but they seems to be inaccurate in the city level. the information i want is (Country, City, longitude, latitude) i want the country and the city to be very accurate if possible.

I have also used HTML5 but the problem that it asks my user to share location information which seems to me bad solution. (althougth i got very accurate results)

Any solutions?

_{Notice: i found google search got an accurate detection and without "ask for sharing my location", but i didn't find any api to use google service}

The IP addresses may be changed depends on ISP and I think that is the reason why the geolocation database is not always accurate. You can compare the accuracy among these geolocation sites other than maxmind. www.geobytes.com, www.hostip.info, www.ip2location.com

I hope these links might help you. First two links have a database of geolocation information with respect to IP addresses. Whereas the links 3,4, & 5 work on traceroute command. Let me know if these work for you .

This is a code i found for a tutorial for Geo Location using Google maps.. Hope this is useful.

This works on the way you connect to the network.

if you use a Boradband ISP what gives you an fixed ip your location will be more accurate.
if you use mobile device to connect to internet, the Location of the nearest Mobile tower from which your network gets the signal will be shown

Example for HTML5 Geolocation

<!DOCTYPE html>
<html>
<head>
<title>GeoLocation Demo</title>
<meta charset="utf-8"/>
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>
<script>
  var startPos;
  var map;

  function init() {
      if (navigator.geolocation) {
          document.getElementById("support").innerHTML = "<p style='color:green'>Great! This browser supports HTML5 Geolocation</p>";
          navigator.geolocation.getCurrentPosition(updateLocation, handleLocationError, {
              timeout: 50000
          });
          //navigator.geolocation.watchPosition(updateCurrPosition,handleLocationError);

      } else {
          document.getElementById("support").innerHTML = "<p style='color:red'>Oops! This browser does not support HTML5 Geolocation</p>";
      }
  }

  function updateLocation(position) {
      startPos = position;
      var latitude = position.coords.latitude;
      var longitude = position.coords.longitude;

      //document.getElementById("startLat").innerHTML = latitude;
      //document.getElementById("startLon").innerHTML = longitude;

      var coords = new google.maps.LatLng(latitude, longitude);

      var mapOptions = {
          zoom: 10,
          center: coords,
          mapTypeControl: false,
          navigationControlOptions: {
              style: google.maps.NavigationControlStyle.SMALL
          },
          mapTypeId: google.maps.MapTypeId.ROADMAP
      };

      map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

      var marker = new google.maps.Marker({
          position: coords,
          map: map,
          title: "Your current location!"
      });

  }

  function handleLocationError(error) {
      switch (error.code) {
          case 0:
              updateStatus("There was an error while retrieving your location: " + error.message);
              break;

          case 1:
              updateStatus("The user prevented this page from retrieving the location.");
              break;

          case 2:
              updateStatus("The browser was unable to determine your location: " + error.message);

              break;

          case 3:

              updateStatus("The browser timed out before retrieving the location.");

              break;
      }
  }

  function updateStatus(msg) {
      document.getElementById("divStatus").innerHTML = msg;
  }
</script>
</head>

<body onload="init()">  
<div id="support"></div>
<div id="divStatus"></div>
<div id="map_canvas" style="width:600px;height:400px;"></div>
</body>
</html>
