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:
From geostationary altitude, the entire Earth disk only subtends an angle of 17.4 degrees. A typical polar orbiting meteorological satellite, at an altitude of about 850 km, sees a relatively small portion of the globe at any one time. For example, the Advanced Very High Resolution Radiometer or AVHRR scans a swath that is 110.8 degrees in width, corresponding to a surface distance of roughly 3000 km.
