Step-by-Step Mathematical Derivation
1. Given Input Coordinates:
- Start Point: (40.7128°, -74.006°)
- Bearing: 45°
- Distance: 100 km
2. Model & Ellipsoid Reference:WGS-84 / Earth Sphere R = 6,371 km
3. Governing Geodesic Formula:
φ2 = asin(sin(φ1)cos(d/R) + cos(φ1)sin(d/R)cos(θ))4. Variable Substitution:
R = 6,371 km5. Interpretation & Practical Application:
Traveling 100 km at bearing 45° arrives at coordinates (41.345636°, -73.15895°).
Mathematical Formula
lat2 = asin(sin(lat1)cos(d/R) + cos(lat1)sin(d/R)cos(θ))
Overview & Explanation
Performs spherical dead reckoning to project new coordinates along a given vector.
How It Works
- Projects distance along great circle at initial azimuth.
