The Google Santa Tracker is an annual holiday tradition that allows people to follow the journey of Santa Claus as he travels around the world delivering presents on Christmas Eve. The tracker is available online and as a mobile app, and it features a variety of interactive games, activities, and educational content related to Christmas and the winter holidays.
The NORAD Santa Tracker is run by the North American Aerospace Defense Command (NORAD), a joint military organization between the United States and Canada that is responsible for the air, land, and sea defense of North America. Working with Cesium, a platform for developers to build web-based 3D map apps, NORAD has built a 3D tracker that displays Santa's whereabouts. The 3D tracker app uses Bing Maps satellite imagery to give a realistic texture to the 3D globe rendered by the CesiumJS library.
For devices that do not support 3D, the app falls back to a 2D map. That tracker map displays a pin marking Santa's current location for you to follow. You can also learn more about each location Santa visits by clicking on an icon that brings up Wikipedia articles and Santa Cam videos that you can play.
