Show Raster Image on the Map

This tutorial shows how to add a raster image overlay to the map.

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

2. Install the npm package.

3. Include the CSS file.

   If you have a bundler that can handle CSS, you can import the CSS or include it with a <link> in the head of the document via the CDN

4. Include the following code in your JavaScript file (Example: app.js).

5. Replace YOUR_MAPTILER_API_KEY_HERE with your actual MapTiler API key.

6. The next is 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. See what’s available here.

7. Add event handler for map load event. You will add code to create an image source and image layer in this handler.

   
        map.on('load', function() {
           
        });
    

8. Create image source. Here you can get the example image aerial_wgs84.png

   
        map.on('load', function() {
            map.addSource("aerial-source", {
                "type": "image",
                "url": "img/aerial_wgs84.png",
                "coordinates": [
                    [4.639663696289062, 50.900867668253724],
                    [4.642066955566406, 50.900867668253724],
                    [4.642066955566406, 50.89935199434383],
                    [4.639663696289062, 50.89935199434383]
                ]
            });
        });
    

9. Add the image layer

   
        map.addLayer({
            "id": "overlay",
            "source": "aerial-source",
            "type": "raster",
            "paint": {
                "raster-opacity": 0.85
            }
        });
