With the below code i can able to autopulate Latitude and Longtitude based address specified

{!REQUIRESCRIPT("https://maps-api-ssl.google.com/maps/api/js?v=3&sensor=false")} 
{!REQUIRESCRIPT("https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js")} 
{!REQUIRESCRIPT("../../soap/ajax/26.0/connection.js")} 

var address ='{!Apartment_Property__c.Address_Street__c}, ' + '{!Apartment_Property__c.City__c}, ' + '{!Apartment_Property__c.State__c}, ' + '{!Apartment_Property__c.Country__c}'; 

sforce.connection.sessionId = '{!$Api.Session_ID}'; 

var geocoder = new google.maps.Geocoder(); 
var geocoderRequest = { 
address: address 
} 

geocoder.geocode(geocoderRequest, function(results, status){ 
if(status == google.maps.GeocoderStatus.OK) { 

var googleAddress = results[0].formatted_address; 
var lat = results[0].geometry.location.lat(); 
var lng = results[0].geometry.location.lng(); 
console.log('======googleAddress=====>' + googleAddress + '==== latitude ====>' + lat + '==== longitude ====>' + lng); 

// updating a Propertylocation record 
var PropertyTest = new sforce.SObject("Apartment_Property__c"); 
PropertyTest.id = "{!Apartment_Property__c.Id}"; 
PropertyTest.Geolocation__Latitude__s = lat; 
PropertyTest.Geolocation__Longitude__s = lng; 
sforce.connection.update([PropertyTest]); 
window.parent.location = "/"+PropertyTest.id;//to reload the window and show the updated values 

} 
else if(status = google.maps.GeocoderStatus.ZERO_RESULTS) { 
//YOUR LOGIN 
} 
else if(status = google.maps.GeocoderStatus.OVER_QUERY_LIMIT) { 
// YOUR LOGIC 
} 
else if(status = google.maps.GeocoderStatus.INVALID_REQUEST) { 
// YOUR LOGIC 
} 
});

Step 1 : Create a trigger that will call the apex callouts 
Step 2 : Create an apex class 
Here the endpoint URL that you need to use 

http://maps.google.com/maps/api/geocode/json?address=300+Collins+St,+Docklands,+VIC&sensor=false&components=country:AU
Please refer this link for same sample code

Thanks for your quick response!

I have quick question on apex class, what is string value here, am getting error on this line String address = '';

The address whihc you wanted to fetch the  latitude 
Ramk123Ramk123
I didn't get you, Let me explain you the issue once again. When i complie the Apex Callout am getting errors because of Address string is empty 
Error Message :

Error: Compile Error: Invalid identifier '’'. Apex identifiers must start with an ASCII letter (a-z or A-Z) followed by any number of ASCII letters (a-z or A-Z), digits (0 - 9), '$', '_'. at line 12 column 28

Apex Callout:
public class LocationCallouts {
@future(callout=true)
static public void newAccmethod(set<id> li){
for(Account a : [SELECT BillingCity,BillingCountry,BillingPostalCode,BillingState,BillingStreet FROM Account WHERE id =: li]){
String address = ''; 
if (a.BillingStreet != null)
address += a.BillingStreet +’, ‘; -->Error location is here 
if (a.BillingCity != null)
address += a.BillingCity +’, ‘;
if (a.BillingState != null)
address += a.BillingState +’ ‘;
if (a.BillingPostalCode != null)
address += a.BillingPostalCode +’, ‘;
if (a.BillingCountry != null)
address += a.BillingCountry;
address = EncodingUtil.urlEncode(address, ‘UTF-8’);
// build callout
Http h = new Http();
HttpRequest req = new HttpRequest();
req.setEndpoint(‘http://maps.googleapis.com/maps/api/geocode/json?address=’+address+’&sensor=false’);
req.setMethod(‘GET’);
req.setTimeout(5000);
try{
// callout
HttpResponse res = h.send(req);
// parse coordinates from response
JSONParser parser = JSON.createParser(res.getBody());
double lat = null;
double lon = null;
while (parser.nextToken() != null) {
if ((parser.getCurrentToken() == JSONToken.FIELD_NAME) &&
(parser.getText() == ‘location’)){
parser.nextToken(); // object start
while (parser.nextToken() != JSONToken.END_OBJECT){
String txt = parser.getText();
parser.nextToken();
if (txt == ‘lat’)
lat = parser.getDoubleValue();
else if (txt == ‘lng’)
lon = parser.getDoubleValue();
}
}
}
// update coordinates if we get back
if (lat != null){
system.debug(lat+’ ‘+lon);
a.Geo__Latitude__s = lat;
system.debug(a.Geo__Latitude__s+’a.Geo__Latitude__s’);
a.Geo__Longitude__s = lon;
system.debug(a.Geo__Longitude__s +’a.Geo__Longitude__s’);
update a;
}
}
catch (Exception e) {
system.debug(e);
}
}
}
}

I used MapBox api to get location and gps coordinates of a User. You can check here example of getting longitude and latitude using an API.
