18 sty 2024 · Here are the numbers: a = 6378137.8 m. a = 6 378 137.8\ \mathrm {m} a= 6378137.8 m; b ≈ 6356752.314140 m. b \approx 6 356 752.314140\ \mathrm {m} b ≈6356752.314140 m; and. f = 298.257223563. f = 298.257 223 563 f =298.257223563. We will now introduce Vincenty's formula to calculate the great circle on an ellipsoid.
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.
Air Distance & Flight Time Calculation The Great Circle Mapper. Draw you flight path on a map and calculate the great circle distance in nautical miles and kilometers. Get estimat
const c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)); const d = R * c; // in metres. Note in these scripts, I generally use lat/lon for latitude/longitude in degrees, and φ/λ for latitude/longitude in radians – having found that mixing degrees & radians is often the easiest route to head-scratching bugs...
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. Great Circle Map

dist = acos (sin ( lat1) × sin ( lat2 ) + cos ( lat1) × cos ( lat2 ) × cos ( theta )) if ( dist < 0) dist = dist + pi. dist = dist × 6371.2. The resulting distance is in kilometers. Q: Does the Great Circle Mapper assume Earth is a sphere?
