Earth curvature line of sight
WebThe longest ground to ground line of sight observations are less than 300 miles. If the earth were flat, we should be able to reliably and consistently see almost all the terrain around us for 100 miles. If the Gleason projection is accurate, the earth is around 25,000 miles in diameter from “ice wall” to “ice wall”. WebAug 2, 2024 · Line-of-Sight & Proximity to Local Broadcast TV Towers. ...
