Curvature of the earth per km
WebNumerically, the radius of the Earth varies a little with latitude and direction; but a typical value is 6378 km (about 3963 miles). If h is in meters, that makes the distance to the geometric horizon 3.57 km times the square root of the height of the eye in meters (or about 1.23 miles times the square root of the eye height in feet). Webcurvature of the Earth, correction for [SURVEYING]-1 That offset from the tangent to the curve resulting from curvature of the Earth. The offset amounts to about 8 cm at 1 km distance. 2 That offset which is given in surveying tables as correction for curvature of the Earth. The values given in such tables usually combine the effects of both ...
