WebIt's hard to see the curvature of the earth from an altitude of 7 miles or 37,000 ft (typical cruising altitude of a jetliner) but easy to see from 250 miles (typical altitude of the ISS). The line of sight from an aircraft at 37,000 feet = 235 miles. That's only about 3.4 degrees of the earth's surface. bisto products https://beautydesignbyj.com

WebTortuosity in 2-D. Subjective estimation (sometimes aided by optometric grading scales) is often used. The simplest mathematical method to estimate tortuosity is the arc-chord ratio: the ratio of the length of the curve (C) to the distance between its ends (L): = Arc-chord ratio equals 1 for a straight line and is infinite for a circle.
