Indoor Maps

HERE Indoor Maps provides a wealth of hyperlocal information about indoor spaces including building geometry and points of interest, spanning across multiple floors. If you are a building owner and are interested in leveraging HERE Indoor Maps with the Maps API for Javascript, contact us at

Setting up HERE Indoor Maps

The following is required to use HERE Indoor Maps in the Maps API:

  1. The app credentials must have access to the requested Indoor Map.

  2. Include the HERE Indoor Maps module script in the <head> section of the HTML page:

<!DOCTYPE html>
  <script src=""
  <script src=""
  <script src=""
  <script src=""
  <script src=""

Displaying data on map

To create the map, make sure to follow the Quick Start guide.

Loading the Indoor Map

Use the platform object to get the instance of H.venues.Service to load your Indoor Maps and create a H.venues.Provider object to control of the loaded Indoor Maps:

// Get instance of the Indoor Maps service
const venuesService = platform.getVenuesService({ apikey: 'API KEY' });

// Indoor Maps provider interacts with a tile layer to visualize and control the Indoor Map
const venuesProvider = new H.venues.Provider();

// Indoor Maps service provides a loadVenue method
venuesService.loadVenue(VENUE_ID).then((venue) => {
  // add Indoor Map to the venues provider

 // create a tile layer for the Indoor Maps provider

  // center the map on the Indoor Map

Example Indoor Map

The example above shows an Indoor Map on the map.

Changing levels

The Provider facilitates the control of the Indoor Map. To get information about the current level or change the level:

// Get active Indoor Map
const venue = venuesProvider.getActiveVenue();

// get current level index

// and change level

The H.venues.Venue object provides a search functionality through the search method. The search string is not case sensitive and also looks for close matches:

// Get the active Indoor Map
const venue = venuesProvider.getActiveVenue();

// Search for bathrooms'Bathroom');

Indoor Maps User Interface

Default UI elements control Drawings and Levels using H.venues.ui.DrawingControl and H.venues.ui.LevelControl:

// Get the active Indoor Map
const venue = venuesProvider.getActiveVenue();

// Create the level control
const levelControl = new H.venues.ui.LevelControl(venue);
ui.addControl('level-control', levelControl);

// Create the drawing control:
const drawingControl = new H.venues.ui.DrawingControl(venue);
ui.addControl('drawing-control', drawingControl);

Indoor Map objects

The Indoor Map data is encapsulated in a hierarchy of objects. These objects perform as other MapObjects and are represented by the following classes:

  • H.venues.Venue
  • H.venues.Drawing
  • H.venues.Level
  • H.venues.Geometry

The root is Venue, which contains one or more Drawings, which contains one or more Levels. And the Level object holds the relevant collection Geometry objects.

The raw data associated with each object is accessible through the getData() method.

Indoor Routing

The classes H.venues.Service and H.venues.Route enable calculating a route between points and visualizing the route on the map in a few simple steps.

Calculating a route

To calculate a route to or from a building, it is required to provide a point as well as the venue id and the level id for the point. Let's replace the origin and destination in the example below with one point inside the Indoor Map and one outside:

// Calculate the route
const result = await venuesService.calculateRoute({
  // Provide latitude and longitude for an origin point outside a building
    coordinates: [52.15, 5.38]
  // Provide latitude, longitude and venue information for a destination point inside a building:
    venueId: VENUE_ID,
    levelId: LEVEL_ID
  transportMode: 'pedestrian',

Visualizing the route

The resulting route data can be visualized using the class H.venues.Route:

// Create a route object using the data for the route
const route = new H.venues.Route(result.routes[0]);

// Get Indoor Map objects representing indoor segments
const indoorObjects = route.getIndoorObjects();

// Link map objects with venue levels for automatic visibility updates and add to the map
for (let venueId in indoorObjects) {
  for (let levelIndex in indoorObjects[venueId]) {
    const venue = venuesProvider.getVenue(venueId);
    const objectGroup = indoorObjects[venueId][levelIndex];

    // Add objects to the map

    // Link to an Indoor Map level
    venue.setMapObjects(objectGroup.getObjects(), levelIndex);

// Get map objects representing outdoor segments
const outdoorObjects = route.getOutdoorObjects();

// Add objects to the map

Customizing the route style

Using the H.venues.Route's optional styleCallback parameter supports customization of the the route style. The styling requires three parameters:

  • The index of the current route section
  • All route sections
  • Segment object type

Based on the given input, the callback returns the style object ( or or undefined. In the latter case, the map object won't be created.

// Define line and marker styles for segments
const indoorRouteSegmentStyle = new{strokeColor: '#1ab4bf', lineWidth: 3});
const outdoorRouteSegmentStyle = new{strokeColor: '#1ab4bf', lineWidth: 3});

const exampleSvgIcon = new
  '<svg width="18" height="18" ' +
    'xmlns="">' +
    '<circle cx="8" cy="8" r="8" ' +
      'fill="#1ab4bf" stroke="white" stroke-width="2"  />' +
const routeStartIcon = exampleSvgIcon;
const routeEndIcon = exampleSvgIcon;
const sectionStartIcon = exampleSvgIcon;
const sectionEndIcon = exampleSvgIcon;

//  Define attribution logic based on segments and objects of the route
const styleCallback = (index, sections, objectType) => {
  if (objectType === H.venues.Route.ObjectType.SEGMENT_START_MARKER) {
    if (index === 0) {
      return routeStartIcon;
    return sectionStartIcon;
  } else if(objectType === H.venues.Route.ObjectType.SEGMENT_FINISH_MARKER) {
    if (sections.length === 1 || index === sections.length - 1) {
      return routeEndIcon;
    return sectionEndIcon;

  return sections[index] === 'indoor' ?
    indoorRouteSegmentStyle : outdoorRouteSegmentStyle;

// Create route by specifying the styleCallback
const route = new H.venues.Route(result.routes[0], styleCallback);

// Add route to the map using the previous steps
