WebEarth Curve Calculator. This app calculates how much a distant object is obscured by the earth's curvature, and makes the following assumptions: the earth is a convex … WebPhotographs purporting to show the curvature of the Earth are always suspect because virtually all camera lenses project an image that suffers from barrel distortion. To accurately assess curvature from a photograph, the horizon must be placed precisely in the center of the image, i.e., on the optical axis.
