Curvature correction in electronic distance measurement
Abstract The usual methods for curvature correction, which consist of a geometric and a velocity component, are based on standard atmospheric conditions and thus take no account of variable refraction. A formula has been developed expressing the correction as a function of atmospheric refraction: K=(1-$ k_^{2} $ $ S^{2} $/(24 $ R^{2} $) whereS is the measured distance, R is the radius of the earth, and k is the coefficient of refraction. This formula leads to a practical procedure employing trigonometric levelling in the determination of curvature correction for long-range geodimeter measurements.
