Display a 3D terrain map

This tutorial demonstrates how to create a 3D map and display it on a web page using MapTiler Cloud data.

  1. Copy the following code, paste it into your favorite text editor, and save it as a .html file.

  2. Replace YOUR_MAPTILER_API_KEY_HERE with your actual MapTiler API key.

  3. The next it’s up to you. You can start the map in a different place by modifying the starting position and starting zoom, and you can change the look of the map to any of our styles, or yours, by updating the style URL. See what’s available here.</li>

  4. Install the npm package.

  5. Include the CSS file in the <head> of your HTML file.

    Including it with a <link> in the head of the document via the CDN is the simplest and easiest way to provide the CSS, but it is also bundled in the MapLibre module, meaning that if you have a bundler that can handle CSS, you can import the CSS from maplibre-gl/dist/maplibre-gl.css.
  6. Include the following code in your JavaScript file (Example: app.js).

  7. Add event handler for map load event. You will add code to create a GeoJSON source and a vector layer in this handler.

    
         map.on('load', function() {
            
         });
     
  8. Add a “raster-dem” source that contains the terrain elevations (RGBA tiles) to the map.

    
     map.on('load', function() {
       map.addSource("terrain", {
         "type": "raster-dem",
         "url": `https://api.maptiler.com/tiles/terrain-rgb-v2/tiles.json?key=${key}`
       });
     });
     
  9. Enable the 3D terrain of the map indicating the data source.

    
       map.setTerrain({
         source: "terrain"
       });
     
  10. Add options to the map to load the map with a 3D view

    
     const map = new maplibregl.Map({
         container: 'map', // container id
         style: `https://api.maptiler.com/maps/outdoor/style.json?key=${key}`, // style URL
         center: [6.85684, 45.83595], // starting position [lng, lat]
         zoom: 14, // starting zoom
         pitch: 61,
         bearing: 172,
         maxPitch: 85,
         maxZoom: 14
       });
