Real-time vehicle tracking applications rely on the continuous streaming of location data, typically in JSON format, to monitor and display vehicle movements on a map accurately. This is achieved by using real-time data streams that update vehicle locations every second, allowing for smooth transitions and accurate representations on a map. The blog post discusses how to create such an application using the EON JavaScript framework and the Mapbox API, providing a solution for animating real-time data on a map. EON Maps, a standalone library incorporating Mapbox assets, enables users to input geolocation coordinates to render and animate markers on a live-updating map, accurately depicting speed between locations and supporting custom marker styles. The tutorial offers a quick start guide, including a code example for animating a marker across the United States, demonstrating the capabilities of EON Maps in building real-time vehicle tracking systems.
