Hi,

I have two points consisting of long/lat/height. I’d like to calculate the elevation angle between them, as though we were standing at the first point.

If I’ve researched it correctly, we have to place both points on the one plane that is tangent to the surface of the earth at point 1. Then we can use normal vector math to calculate the elevation angle. Is there a gist that shows me how I can do this? I’m confused as to whether I should use eastNorthUpToFixedFrame or geodeticSurfaceNormalCartographic.

Here is the gist I’m trying to calculate the elevation angle for.

Thank you,

Fidel
