How to get the Google Map based on Latitude on Longitude?

Create a URI like this one:

https://maps.google.com/?q=[lat],[long]

For example:

https://maps.google.com/?q=-37.866963,144.980615

or, if you are using the javascript API

map.setCenter(new GLatLng(0,0))

This, and other helpful info comes from here:

https://developers.google.com/maps/documentation/javascript/reference/?csw=1#Map

this is the javascript to display google map by passing your longitude and latitude.

<script>
    function initialize() {
      var myLatlng = new google.maps.LatLng(-34.397, 150.644);
      var myOptions = {
        zoom: 8,
        center: myLatlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
      }
      var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    }

    function loadScript() {
      var script = document.createElement("script");
      script.type = "text/javascript";
      script.src = "http://maps.google.com/maps/api/js?sensor=false&callback=initialize";
      document.body.appendChild(script);
    }

    window.onload = loadScript;


</script>
