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. WebThe curvature would mean the earth's level surface is lower than horizontal. 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. The formulas are reasonably good for the difference in typical conditions.
