How does one calculate a visual line of sight for objects at a given height that are distant enough that the Earth's curvature needs to be considered? Why might a photographer find such information useful? Estimate Earth curvature drop for any travel distance. Here’s the first question, from 1997: Curvature is technically measured in terms of the angular turn per unit distance, in various ways; as we’ll see throughout this post, trying to measure it in terms of distances only, while it seems to be a natural idea, causes some trouble. But the second question here, about how things change when you double t Nov 10, 2025 · Learn how to calculate the Earth’s geometric curvature, why atmospheric refraction changes what you see, and its impact on engineering. As a result, on a flat surface with your eyes 5 feet or so off the ground, the farthest edge that you can see is about 3 miles away. Accurately calculate the curvature on the ball Earth. The Earth curvature calculator lets you find the distance from you to the horizon, as well as the height of an object that is partially hidden behind it. Uses a cosine function, works for all distances in both kilometers and miles. Sep 23, 2022 · Earth's curvature The Earth curves about 8 inches per mile.
