AngularJs share $scope between controller and controller

I can't understand why I can't access to $scope properties from the directive, the documentation says that directives doesn't create new scopes, so why can't I acess the $scope properties?

at app.js

'use strict';

var climbingApp = angular.module('climbingApp', []);

climbingApp.controller('ctrl', function($scope) {

    $scope.initLocation = {
        lat: -54.798112,
        lng: -68.303375
    };

at google-map.js

'use strict';

climbingApp.directive('gmap', function() {
        return {
            restrict: 'E',
            replace: true,
            template: '<div id="map-canvas"></div>',
            link: function(scope, iElement, attrs) {
                console.log(scope.initLocation);
            },
        }

    })

at index.html

  <html ng-app="climbingApp">
     <body>
    <gmap></gmap>

    </body>
    </html>

<script src="//code.angularjs.org/1.2.0-rc.2/angular.min.js"></script>

<script src="app/app.js"></script>
<script src="app/dependencies/google-maps.js"></script>

The console.log always returns undefined.

You have to associate the controller with the view (if you use ngRoute) or an element using ng-controller. Something like this:

<body ng-controller="ctrl">...</body>

Inject the $scope in your controller like that : 

var climbingApp = angular.module('climbingApp', ['ngRoute']);


    climbingApp.controller('ctrl', function($scope) {

        $scope.initLocation = {
            lat: -54.798112,
            lng: -68.303375
        };

        $scope.markers = [
            {
                'title' : 'prueba',
                'position' : [-54.798112, -68.303375] 
            },
            {   
                'title': 'prueba', 
                'position': [-54.798212, -68.303375] 
            }
        ];
    });


    'use strict';

    climbingApp.directive('gmap', function() {
            return {
                restrict: 'E',
                replace: true,
                template: '<div id="map-canvas"></div>',
                link: function(scope, iElement, attrs) {
                    console.log(scope.initLocation);
                },
            }

        })

The log appears.

$scope or $location have to be pass in the function of your controller as param.

You need to inject the scope into the controller

climbingApp.controller('ctrl', function($scope) {
