Integrating Google Maps in Salesforce

Requirement is to show the location of my Account on Google Maps. It looks difficult but actually it is very simple to implement.

Just create a new visualforce page with this code
<apex:page standardController="Account">

<script src="http://maps.google.com/maps?file=api">

<script type="text/javascript">

var map = null;
var geocoder = null;

var address = "{!Account.BillingStreet}, {!Account.BillingPostalCode} {!Account.BillingCity}, {!Account.BillingState}, {!Account.BillingCountry}";

function initialize() {
  map = new GMap2(document.getElementById("MyMap"));
  map.addControl(new GMapTypeControl());
  map.addControl(new GLargeMapControl3D());
  geocoder = new GClientGeocoder();
    function(point) {
      if (!point) {
        document.getElementById("MyMap").innerHTML = address + " not found";
      } else {
        map.setCenter(point, 13);
        var marker = new GMarker(point);
        marker.bindInfoWindowHtml("Account Name : <b><i> {!Account.Name} </i></b> <br/> Address : "+address);

<div id="MyMap" style="width:100%;height:300px"></div>
    initialize() ;

As you can see that I have used standard controller so you need to pass the account Id in URL. Let's say if the page name is "GoogleMaps" then the URL will look something like this : ".../apex/GoogleMaps?id=YOUR_ACCOUNT_ID".

When you click on the balloon it will show you the Account name and the address, you can change it according to your need by changing the code of line "marker.bindInfoWindowHtml"

Use this page as in line visualforce page on native layout and enjoy the Google maps with Salesforce.
