Hello,
I've noticed a disagreement between my height data in my CZML (sea level values) and the calculated (interpolated) height reported at runtime ( I see the runtime values by attaching a listener and watching the Entity position change as the Entity travels).
So, we know that height is taken as height above ellipsoid ( see
http://cesiumjs.org/Cesium/Build/Documentation/Cartographic.html ), and that the ellipoid does not necessarily follow sea level.
Question: Do I need to attach a terrain provider to correct this problem?
Thanks !
