hide map. Formula: φ 2 = asin ( sin φ 1 ⋅ cos δ + cos φ 1 ⋅ sin δ ⋅ cos θ ) λ 2 = λ 1 + atan2 ( sin θ ⋅ sin δ ⋅ cos φ 1, cos δ − sin φ 1 ⋅ sin φ 2 ) where. φ is latitude, λ is longitude, θ is the bearing (clockwise from north), δ is the angular distance d/R; d being the distance travelled, R the earth’s radius.

20 maj 2024 · Finally, the new Frankfurt service is shown in the gold that formed half of the inaugural aircraft's striped livery. References and additional information: The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
Compute the great circle route from Valparaíso , φ 1 = −33°, λ 1 = −71.6°, to Shanghai , φ 2 = 31.4°, λ 2 = 121.8°. The formulas for course and distance give λ 12 = −166.6°, [note 8] α 1 = −94.41°, α 2 = −78.42°, and σ 12 = 168.56°. Taking the earth radius to be R = 6371 km, the distance is s12 = 18743 km.
Assuming a sphere of radius 6371.2 km , convert longitude and latitude to radians (multiply by pi /180) and then use the following formula: theta = lon2 - lon1. dist = acos (sin ( lat1) × sin ( lat2 ) + cos ( lat1) × cos ( lat2 ) × cos ( theta )) if ( dist < 0) dist = dist + pi. dist = dist × 6371.2.
Calculate the great circle distance between two points; Calculate the great circle distance between two addresses; Draw a direct route between two airports, or multiple airport pairs; Draw range rings (concentric circles) around a point; Calculate coordinates at a given bearing and distance
Great Circle Map displays the shortest route between airports and calculates the distance. It draws geodesic flight paths on top of Google maps, so you can create your own route map.
