google map displaying default data

iam using google map in my php script to display the address of a c开发者_如何转开发ompany. But the map is only displaying the default city location of the address, not going deep.

For example, if i specify the address as: Angadalavari Street, Behind Bodima Hotel, Kothapet, Vijayawada

But the map is showing only the location Governorpeta, Vijayawada

What could be the reason?

Mentioning the ADDRESS is not enough ..it is better specify the LONGITUDE and LATITUDE for exact location ....

Here is the Sample Code:

    <script type="text/javascript"> 
        function initialize(){
            var latlng = new google.maps.LatLng(18.88411739850852, 84.58428740501404);//Location for BARUVA,ANDHRAPRADESH,INDIA
            var myOptions = {
                zoom: 17,
                center: latlng,
                mapTypeId: google.maps.MapTypeId.HYBRID
            };
            var map = new google.maps.Map(document.getElementById('mapCanvas'), myOptions);
        }
    </script>
