I understand CESIUM returns Height Above Ellipsoid where as GE used to return MSL altitude. Slope calculation we use in our application is (Altitude difference between from Point to Point B)/(Distance between Point A to Point B), as now there is difference of altitude values slope factor is not same as what we used to have.
I was wondering is any there any better way to get the slope factor calculated on cesiumjs.
Also is there any API available to get GEOID Altitude which can be invoked by application and frame the MSL altitude = HAE+GEOID Altitude.
Any help is appreciated. TIA.
