All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
