This is done to account for the …
WebCurvature and Refraction The blue line is the original LoS held at 90° zenith angle. The red line is the refracted LoS. The black line has a constant height (HI) along its length. Figure E-7 is a closeup at the target end. Figure E-7 Curvature and Refraction at Target C is the curvature error. WebFeb 4, 2024 · The Earth's curvature is also visible laterally in the photograph, although the effect is subtle as the image encompasses only 1/360 of the Earth's circumference."
WebJul 12, 2024 · The formula to calculate the effect of the curvature of the Earth on how far can you see is: \footnotesize d = \sqrt { (R_ {\text {E}}+h)^2 - R_ {\text {E}}^2} d = (RE + h)2 − RE2 Where: d d is the calculated distance of the horizon; R_ {\text {E}} RE is the Earth's radius ( 6,371,000\ \text {m} 6,371,000 m ); and h h is the observer's height.
