Getting directions

Last updated: 6/14/2023

Now we have a simple map with a floor selector where you can search for locations. When finishing this step you'll be able to create a directions between two points and change the transportation mode.

Get Directions Between Two Locations

To get Directions between two MapsIndoors Locations, or Places outside of your MapsIndoors Solution, we need two things:

The Directions Service instance
The Directions Render instance

We need the Directions Service to calculate the fastest route between two points, and use the Directions Render to actually draw the route on the map.

Get Directions Service and Render instances

First, initialize the MapsIndoors Directions Service, and add an external Directions Provider (in this case Google Maps).

Then, we need to initialize the MapsIndoors Directions Render with the MapsIndoors instance:

// main.js

const mapViewOptions = {
  element: document.getElementById('map'),
  center: { lat: 38.8974905, lng: -77.0362723 }, // The White House
  zoom: 17,
  maxZoom: 22,
};
const mapViewInstance = new mapsindoors.mapView.GoogleMapsView(mapViewOptions);
const mapsIndoorsInstance = new mapsindoors.MapsIndoors({ mapView: mapViewInstance });
const googleMapsInstance = mapViewInstance.getMap();

+ const externalDirectionsProvider = new mapsindoors.directions.GoogleMapsProvider();
+ const miDirectionsServiceInstance = new mapsindoors.services.DirectionsService(externalDirectionsProvider);
+ const directionsRendererOptions = { mapsIndoors: mapsIndoorsInstance }
+ const miDirectionsRendererInstance = new mapsindoors.directions.DirectionsRenderer(directionsRendererOptions);

// Floor Selector
const floorSelectorElement = document.createElement('div');
new mapsindoors.FloorSelector(floorSelectorElement, mapsIndoorsInstance);
googleMapsInstance.controls[google.maps.ControlPosition.RIGHT_TOP].push(floorSelectorElement);

function onSearch() {
  const searchInputElement = document.querySelector('input');
  // Get list element reference
  const searchResultsElement = document.getElementById('search-results');

  const searchParameters = { q: searchInputElement.value };
  mapsindoors.services.LocationsService.getLocations(searchParameters).then(locations => {
    // Reset search results list
    searchResultsElement.innerHTML = null;

    // Append new search results
    locations.forEach(location => {
      const listElement = document.createElement('li');
      listElement.innerHTML = location.properties.name;
      searchResultsElement.appendChild(listElement);
    });

    // Filter map to only display search results
    mapsIndoorsInstance.filter(locations.map(location => location.id), false);
  });
}

First, add two new let statements all the way at the top, after the miMapElement constant, for storing our Directions Service and Directions Renderer instances. Then, we populate them with the instances within the mapsIndoorsReady event:

// main.js

const miMapElement = document.querySelector('mi-map-googlemaps');
const miSearchElement = document.querySelector('mi-search');
const miListElement = document.querySelector('mi-list');

+ let miDirectionsServiceInstance;
+ let miDirectionsRendererInstance;

miMapElement.addEventListener('mapsIndoorsReady', () => {
  miMapElement.getMapInstance().then((mapInstance) => {
    mapInstance.setCenter({ lat: 38.8974905, lng: -77.0362723 }); // The White House
  });
+ miMapElement.getDirectionsServiceInstance()
+   .then((directionsServiceInstance) => miDirectionsServiceInstance = directionsServiceInstance);

+ miMapElement.getDirectionsRendererInstance()
+   .then((directionsRendererInstance) => miDirectionsRendererInstance = directionsRendererInstance);
})

miSearchElement.addEventListener('results', (event) => {
  // Reset search results list
  miListElement.innerHTML = null;

  // Append new search results
  event.detail.forEach(location => {
    const miListItemElement = document.createElement('mi-list-item-location');
    miListItemElement.location = location;
    miListElement.appendChild(miListItemElement);
  });

  // Get the MapsIndoors instance
  miMapElement.getMapsIndoorsInstance().then((mapsIndoorsInstance) => {
    // Filter map to only display search results
    mapsIndoorsInstance.filter(event.detail.map(location => location.id), false);
});

First, initialize the MapsIndoors Directions Service, and add an external Directions Provider (in this case Mapbox).

Then, we need to initialize the MapsIndoors Directions Render with the MapsIndoors instance:

// main.js

const mapViewOptions = {
  accessToken: "YOUR_MAPBOX_ACCESS_TOKEN",
  element: document.getElementById("map"),
  center: { lat: 38.8974905, lng: -77.0362723 }, // The White House
  zoom: 17,
  maxZoom: 22,
};
const mapViewInstance = new mapsindoors.mapView.MapboxView(mapViewOptions);
const mapsIndoorsInstance = new mapsindoors.MapsIndoors({ mapView: mapViewInstance });
const mapboxInstance = mapViewInstance.getMap();

+ const externalDirectionsProvider = new mapsindoors.directions.MapboxProvider('YOUR_MAPBOX_ACCESS_TOKEN');
+ const miDirectionsServiceInstance = new mapsindoors.services.DirectionsService(externalDirectionsProvider);
+ const directionsRendererOptions = { mapsIndoors: mapsIndoorsInstance }
+ const miDirectionsRendererInstance = new mapsindoors.directions.DirectionsRenderer(directionsRendererOptions);

// Floor Selector
const floorSelectorElement = document.createElement('div');
new mapsindoors.FloorSelector(floorSelectorElement, mapsIndoorsInstance);
mapboxInstance.addControl({ onAdd: function () { return floorSelectorElement }, onRemove: function () { } });

function onSearch() {
  const searchInputElement = document.querySelector('input');
  // Get list element reference
  const searchResultsElement = document.getElementById('search-results');

  const searchParameters = { q: searchInputElement.value };
  mapsindoors.services.LocationsService.getLocations(searchParameters).then(locations => {
    // Reset search results list
    searchResultsElement.innerHTML = null;

    // Append new search results
    locations.forEach(location => {
      const listElement = document.createElement('li');
      listElement.innerHTML = location.properties.name;
      searchResultsElement.appendChild(listElement);
    });

    // Filter map to only display search results
    mapsIndoorsInstance.filter(locations.map(location => location.id), false);
  });
}

// main.js

const miMapElement = document.querySelector('mi-map-mapbox');
const miSearchElement = document.querySelector('mi-search');
const miListElement = document.querySelector('mi-list');

+ let miDirectionsServiceInstance;
+ let miDirectionsRendererInstance;

miMapElement.addEventListener('mapsIndoorsReady', () => {
  miMapElement.getMapInstance().then((mapInstance) => {
    mapInstance.setCenter({ lat: 38.8974905, lng: -77.0362723 }); // The White House
  });
+ miMapElement.getDirectionsServiceInstance()
+   .then((directionsServiceInstance) => miDirectionsServiceInstance = directionsServiceInstance);

+ miMapElement.getDirectionsRendererInstance()
+   .then((directionsRendererInstance) => miDirectionsRendererInstance = directionsRendererInstance);
})
miSearchElement.addEventListener('results', (event) => {
  // Reset search results list
  miListElement.innerHTML = null;

  // Append new search results
  event.detail.forEach(location => {
    const miListItemElement = document.createElement('mi-list-item-location');
    miListItemElement.location = location;
    miListElement.appendChild(miListItemElement);
  });

  // Get the MapsIndoors instance
  miMapElement.getMapsIndoorsInstance().then((mapsIndoorsInstance) => {
    // Filter map to only display search results
    mapsIndoorsInstance.filter(event.detail.map(location => location.id), false);
});

See all available directions render options and methods in the reference documentation.

Now our example app is ready to provide Directions. Next up is how to give it an Origin and Destination and draw the route between.

Draw a Route on the Map

To display a route on the map, we use the coordinates of an Origin and Destination and draw a line between them. For this, we use MapsIndoors' directionsRenderer.

The Destination coordinate is retrieved dynamically, using the coordinate of the selected Location in the search results list. Therefore, you must search for the destination to get directions, and then click the result, in the text list. Different solutions can of course be implemented into your own solution later. In this tutorial, the Origin is a hardcoded coordinate.

In the following example, this is what happens:

Create a new getRoute method in main.js which accepts a location
Create two new constants, one for the Origin's coordinate, and another for the Destination's coordinate
Add another constant defining the routeParameters
Using the MapsIndoors Directions Service call the getRoute method to get the fastest route between the two coordinates

See all available route parameters in the reference documentation.
Using the MapsIndoors Directions Renderer call the setRoute method to display the route on the map

  const routeParameters = {
    origin: originLocationCoordinate,
    destination: destinationCoordinate,
    travelMode: 'WALKING'
  };

  // Get route from directions service
  miDirectionsServiceInstance.getRoute(routeParameters).then((directionsResult) => {
    // Use directions render to display route
    miDirectionsRendererInstance.setRoute(directionsResult);
  });
}

Now you can click on each item in the search results list to get directions from The Oval Office to any Location in The White House.

Change Transportation Mode

In MapsIndoors, the transportation mode is referred to as travel mode. There are four travel modes, walking, bicycling, driving and transit (public transportation). The travel modes generally applies for outdoor navigation. Indoor navigation calculations are based on walking travel mode.

To change between travel modes we first need to add a <select> element with all four transportation options above the search field:

To use the chosen transportation when getting a route, we need to replace the hardcoded value for travelMode parameter inside the getRoute method with the <select> elements value:

If you have followed the tutorial exactly so far, you will now have something like this (due to technical limitations, only the Google Maps result is shown on this page, but Mapbox implementation will also work if you followed this guide):
