As the surface of the earth is curved, the vertical difference (VD and
Z) at the measurement point, as referenced to the horizontal plane,
will inevitably include some error. This error is called curvature
error. Likewise, as the density of the air surrounding the earth
decreases with altitude, light is refracted when it passes through the
air. The subsequent error caused by this refraction is called
refraction error.
