/**
 * Boilerplate map initialization code starts below:
 */

//Step 1: initialize communication with the platform
var platform = new H.service.Platform({
  app_id: 'DemoAppId01082013GAL',
  app_code: 'AJKnXv84fjrb0KIHawS0Tg',
  useCIT: true,
  useHTTPS: true
});
var defaultLayers = platform.createDefaultLayers();

//Step 2: initialize a map - this map is centered over Europe
var map = new H.Map(document.getElementById('map'),
  defaultLayers.normal.map,{
  center: {lat:52, lng:5},
  zoom: 5
});

//Step 3: make the map interactive
// MapEvents enables the event system
// Behavior implements default interactions for pan/zoom (also on mobile touch environments)
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));

// Create the default UI components
var ui = H.ui.UI.createDefault(map, defaultLayers);


// Now use the map as required...
