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.

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

    
           zoom: 14, // starting zoom
         });
         map.on('load', function() {
            
         });
         map.on('error', function(err) {
     
  5. 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/tiles.json?key=${key}`
       });
     });
     
  6. Enable the 3D terrain of the map indicating the data source.

    
     map.on('load', function() {
       map.addSource("terrain", {
         "type": "raster-dem",
         "url": `https://api.maptiler.com/tiles/terrain-rgb/tiles.json?key=${key}`
       });
       map.setTerrain({
         source: "terrain"
       });
     });
     
  7. 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
       });
