How to display disputed borders based on visitor’s location

This tutorial shows how to automatically change disputed borders based on the geographical location of your map visitor’s location using the MapTiler Geolocation API.

By following this tutorial, you will be able to dynamically adjust disputed borders based on the location of the person accessing the map on your application or according to the official policy of the country your visitor joined from. The MapTiler Geolocation API serves as a powerful tool in achieving this functionality.

  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 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.

  7. Create the showDisputedBorders function. This function changes the filters of the disputed border layers to show or hide the borders depending on the country’s policy.

  8. Add event handler for map load event. You will add code to change disputed borders according to your map visitor’s location in this handler.

  9. Get the user’s IP country code and call the showDisputedBorders function.
