Moving turning points Effects of Curvature and Refraction Due to curvature of the Earth, the line of sight at the instrument will deviate from a horizontal line as one moves away from the level. The earth’s curvature causes … 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. desert west sports complex address
