JavaScript

/**
 * Moves the map to display over Berlin
 *
 * @param  {H.Map} map      A HERE Map instance within the application
 */

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

//Step 1: initialize communication with the platform
// In your own code, replace variable window.apikey with your own apikey
var platform = new H.service.Platform({
  apikey: window.apikey
});
var defaultLayers = platform.createDefaultLayers();

//Step 2: initialize a map - this map is centered over Europe
var map = new H.Map(document.getElementById('map'),
  defaultLayers.vector.normal.map,{
  center: {lat:50, lng:5},
  zoom: 2,
  pixelRatio: window.devicePixelRatio || 1
});
// add a resize listener to make sure that the map occupies the whole container
window.addEventListener('resize', () => map.getViewPort().resize());

//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...
window.onload = function () {
	
  // Create a provider for a semi-transparent heat map:
  var heatmapProvider = new H.data.heatmap.Provider({
    colors: new H.data.heatmap.Colors({
      '0': 'blue',
      '0.5': 'red',
      '1': 'yellow'
    }, true),
    opacity: 0.7,
    // Paint assumed values in regions where no data is available
    assumeValues: false
  });

  // Add the data:
  heatmapProvider.addData([
    {lat: 52, lng: 13, value: 3},
    {lat: 52, lng: 13.5, value: 1},
    {lat: 52, lng: 14, value: 3}
  ]);


  // Add a layer for the heatmap provider to the map:
  map.addLayer(new H.map.layer.TileLayer(heatmapProvider));
  
  moveMapToBerlin(map);
