I work in a UE 5.x project with the Cesium Plugin.
I noticed that if I place a shape on the sea, that is supposed to be at 0 meters more or less, the Cesium Globe Anchor returns an altitude value of 43ish. I work around Italy but I placed the georeference not too far away.
Anyone had any tip regarding this issue? What I could check?
The “height” value in the Longitude / Latitude / Height system does not refer to height above sea level. It refers to the height above the WGS84 Ellipsoid, which is the model used by Cesium Native to do globe-position computations.
Do you need to compute the height above sea level for your application?
