Earth curvature line of sight
WebThis brings up the Setup Line of Sight/Earth Curvature dialog (pictured below), which allows the user to configure a line of sight calculation along the selected path. Line of sight analysis can only be performed on a line made up of two points in the path profile (e.g. line of sight analysis cannot be performed on multi-segment paths). ... WebThe longest ground to ground line of sight observations are less than 300 miles. If the earth were flat, we should be able to reliably and consistently see almost all the terrain around us for 100 miles. If the Gleason projection is accurate, the earth is around 25,000 miles in diameter from “ice wall” to “ice wall”.

WebSpecifies whether the earth's curvature will be taken into consideration for the line-of-sight analysis. For this parameter to be active, the surface must have a defined spatial reference in projected coordinates with defined z-units. Unchecked—The earth's curvature will not be taken into consideration. This is the default.

As such, the farthest edge you can see standing on a flat surface is about 3 miles away. If your vantage point is higher off the ground, the horizon edge gets a lot further away. The earth’s curvature doesn’t cut off objects from your light of sight as soon.

The refraction means your line of sight will be lower than horizontal, but not by as much as the curvature so it doesn't fully cancel out. That leaves the level surface h' below your line of sight.
