Show Point data from GeoJSON on the Map

This tutorial shows how to add a Point GeoJSON overlay 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 own API key. Make sure to protect the key before publishing your map app!

  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 follow this tutorial you can use Airports from Natural Earth. Download the Airports from Natural Earth

  2. Open the data tab on MapTiler choose a new dataset - upload dataset and upload ne_10m_airports.shp.

  3. Publish the dataset and copy the link to the geojson.

  1. Create GeoJSON layer. The following snippet creates GeoJSON layer from an external file with point geometry.

  2. Add style to this layer. Here you can get the example image icon-plane-512.png

  3. Display the 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 Style from 'ol/style/Style.js';
 import Icon from 'ol/style/Icon.js';
 import GeoJSON from 'ol/format/GeoJSON.js';

  2. Create GeoJSON layer. The following snippet creates GeoJSON layer from an external file with point geometry.

  3. Add style to this layer. Here you can get the example image icon-plane-512.png

  4. Display the layer.
