You can absolutely see the earth's curvature if you're at altitude, particularly over the ocean in a plane. At sea level, you can only see about 3 miles. The average angle of human vision is somewhere between 120Âº and 140Âº; more if you count the whole image your brain builds up as your eyes move. The curvature of the horizon can be found with:
The Earth is not spherical, but an ellipsoid of revolution i.e. it is flattened at the Poles - this is a rotational effect (see detailed notes). Satellite studies have provided a very accurate measure of ellipticity:- equatorial radius = 6378 km. polar radius = 6356.6 km. Flattening = (6378 - 6356.6 )/ 6378 = 1 / 298.26
