title: What is the difference between Mapbox GL JS and Cesium?
body: <p>Google earth API has been abolished.
  It seems that the kml file used in Google earth can be used in Cesium. Can it be used in MapBox GL JS?
  Cesium does not have complete 3D building information.
  MapBox GL JS has prepared 3D building information, but I don't know if it can be freely developed for in-house Web applications.</p>
