Greg Beatty from Analytical Graphics, Inc. used Cesium to develop an app to integrate GPS ski track location data with videos taken on a recent ski trip to Salt Lake City, UT.

Cesium is used to show the skier's track on a 3D globe with 10m National Elevation Dataset terrain and high-resolution Bing imagery. Videos taken during the trip are synchronized with the skier's position and play along side of the animating visualization. Billboards are used to indicate the skier's current position and the location of available videos. Camera flights provide smooth transitions to the next location when a user selects a new video to watch.
