Navigate to Google Map from Salesforce

In salesforce we have several requirement to navigate to Account location or Lead location on google map. Mostly sales representative need to navigate to exact account location. In most of the case we look to integrate google map with salesforce which could be costly and will have some maintenance charge as we need to buy google API subscription. Google map navigation can be done without integrating salesforce with google but we have to know account geolocation  co-ordinate where we want to navigate.

To store the Account geolocation co-ordinate, we need to create a custom field in account of data type Geoloction. In this field we can store latitude and longitude of account.

There is two ways of populating this field

  1. By directly populating the value in account record.
  2. We can create a tab on account record page which set current location co-ordinate as geolocation.

Second option is only applicable if we are at account location.

 

Click on set Location to update the account record with current geolocation co-ordinate.

Above Location tab has visualforce page linked to Location Tab.

Find Visualforce page code below.

<apex:page standardController="Account" extensions="GetLocationInAccountController" >
    <!-- Begin Default Content REMOVE THIS -->
    <apex:form id="form">
        <h1>Welcome </h1> Your Location is<br/>

        var geoSuccess = function(position) {

Extension Code

public class GetLocationInAccountController
{
    private ApexPages.StandardController standardController;
    public Decimal Lat{get;set;}
    public Decimal Lon{get;set;}
    
    public GetLocationInAccountController(ApexPages.StandardController standardController)
    {
        this.standardController = standardController;
    }
    
    public PageReference  location(){
        ID recordid=standardController.getId();
        System.debug('ID--'+recordid);
        system.debug('Latitude---'+lat);
        System.debug('Longitude-----'+lon);
        list<Account> ss=new list<Account>();
        for(Account s:[select id,name,Geolocation__Latitude__s,Geolocation__Longitude__s from Account where id=:recordid]){
            s.Geolocation__Latitude__s=Lat;
            s.Geolocation__Longitude__s=lon;
            ss.add(s);
        }
        update ss;
        PageReference pageRef = new PageReference('/'+recordid);
        return pageRef.setRedirect(true);
        
    }
    
}

Once we have account record with geolocation we can create a lightning component which will have account name and buttons to navigate to google map from current location to account location and buttons to know the distance between current location to account location.

Click on Goto Map button to navigate to google map.

Code for the component is given below.

Component:

Apex Controller

public class GoogleMapNavigationController {
    
     @AuraEnabled
    public static List<Account> fetchAccounts(){
           return [SELECT
                Id, Name,Geolocation__Latitude__s,Geolocation__Longitude__s
                FROM Account];
        }
}

Replace geolocation custom field in Apex Controller with your custom field.
