Hi Cesium team,
As the image shown below, terraindb dataset created from geotiff image by terratiller.exe is elevated from the base map( bing maps aerial).
The terraindb dataset was created with parameter
-f Underlying --height-reference Ellipsoid
As a supplement, there is also a point cloud dataset overlapped on terraindb dataset.
Can you explain why is it elevated against to the base map?
Thanks in advance
