We use React to implement this application.įirst, ensure you have Node.js installed on your computer. Now, let’s walk through how to use the TomTom SDK and APIs. To properly follow this tutorial, you need to know some JavaScript and HTML.Īnd if you are unfamiliar with GeoJSON, check out our introductory article here. And now with our geofence in place, we can determine a user’s location in relation to the bordered territory. This will produce a visible geofence that connects the given coordinates, forming the enclosed region. ![]() Then, use the map.addLayer property to collect the area’s coordinates in the GeoJSON format and draw the perimeter. To get started, use TomTom to set up a regular map on a website. Today, let’s explore how to set up a geofence on a TomTom map. Examples include tracking packages, directing users to the nearest store, helping hikers stay within park borders, and much more. Geofences are vastly helpful in many areas. TomTom’s mapping technology can also alert you when the user’s device crosses the border. These borders help determine when a map user is inside or outside the area, or simply nearby. With it, you can draw perimeters on the map to highlight specific states, landmarks, locations, and even entire countries. One of the most efficient ways to create these geofences is with TomTom Maps JavaScript SDK. In short, geofences are virtual borders around specified areas of interest. When it comes to keeping track of people’s locations to provide accurate and efficient service, nothing beats geofences. ![]() Learn how to draw a geofence on a React app map then check if a user is within its border.
