Display a Marker on the map using OpenLayers

This tutorial shows how to add the default marker to the map using OpenLayers.

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

Check out the step-by-step tutorial How to use OpenLayers

  1. Install the npm package.

  2. 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

  3. Include the following code in your JavaScript file (Example: main.js).

  1. Replace YOUR_MAPTILER_API_KEY_HERE with your actual MapTiler API key.

  2. The next is up to you. You can center your map wherever you desire (modifying the starting position) and set an appropriate zoom level (modifying the starting zoom) to match your users’ needs. Additionally, you can change the map’s look (by updating the source URL); choose from a range of visually appealing map styles from our extensive MapTiler standard maps, or create your own to truly differentiate your application.

  1. To create a new marker using a Vector layer. The layer’s data source will be a feature set. Create a feature of the type point at the Lng/Lat coordinates of the marker. Create a Style to load the marker image and finally add it to the current map using .addLayer() function. Download the sample marker image

    
 const layer = new ol.layer.Vector({
 source: new ol.source.Vector({
     features: [
     new ol.Feature({
         geometry: new ol.geom.Point(ol.proj.fromLonLat([12.550343, 55.665957])),
     })
     ]
 }),
 style: new ol.style.Style({
     image: new ol.style.Icon({
     anchor: [0.5, 1],
     crossOrigin: 'anonymous',
     src: 'marker-icon.png',
     })
 })
 });
 map.addLayer(layer);

  1. Import the new modules needed to add the new functionality.

    
 import VectorLayer from 'ol/layer/Vector.js';
 import VectorSource from 'ol/source/Vector.js';
 import Point from 'ol/geom/Point.js';
 import Style from 'ol/style/Style.js';
 import Icon from 'ol/style/Icon.js';
 import Feature from 'ol/Feature.js';

 style: new Style({
     image: new Icon({
     anchor: [0.5, 1],
     crossOrigin: 'anonymous',
     src: 'marker-icon.png',
     })
 })
 });
 map.addLayer(layer);
