Halfway Point Between Two Places Formula:

The geographic midpoint is calculated using spherical trigonometry (The Midpoint Formula):

$$Bx = \cos(\phi_2) \cdot \cos(\Delta\lambda)$$

$$By = \cos(\phi_2) \cdot \sin(\Delta\lambda)$$

$$\phi_m = \text{atan2}(\sin(\phi_1) + \sin(\phi_2), \sqrt{(\cos(\phi_1) + Bx)^2 + By^2})$$

$$\lambda_m = \lambda_1 + \text{atan2}(By, \cos(\phi_1) + Bx)$$

Variables:

  • Latitude A/B ($\phi$): The angular distance north or south of the Equator.
  • Longitude A/B ($\lambda$): The angular distance east or west of the Prime Meridian.
  • $\Delta\lambda$: The difference in longitude between the two points.

What is Halfway Point Calculator?

A halfway point calculator for Google Maps on iPhone determines the exact geographic center between two sets of coordinates. Unlike simple arithmetic means, this tool accounts for the Earth’s curvature, ensuring high accuracy for long-distance travel.

Using this tool helps users identify ideal meeting spots, rest stops, or refueling stations exactly in the middle of a journey. It is specifically optimized for iPhone users who need quick coordinate inputs for mobile navigation.

How to Calculate Halfway Point (Example):

  1. Enter the Latitude and Longitude of New York City (40.71, -74.00).
  2. Enter the Latitude and Longitude of Los Angeles (34.05, -118.24).
  3. Click “Calculate” to determine the spherical midpoint.
  4. View the resulting coordinates (approx. 38.6, -97.3 near Wichita, KS).
  5. Copy the coordinates directly into your Google Maps app.

Frequently Asked Questions (FAQ):

How do I find coordinates on Google Maps iPhone? Long-press any location on the map to drop a pin. Tap “Dropped Pin” at the bottom to see the Latitude and Longitude.

Is the midpoint different from the average distance? Yes. Because the Earth is a sphere, the shortest path (Great Circle) results in a midpoint that is geographically accurate, unlike a straight line on a flat map.

Can I use this for driving directions? This tool provides the geographic center. For driving, the “halfway point” may vary based on road networks and traffic.

Does this work for international locations? Absolutely. It handles all quadrants (N/S, E/W) correctly using decimal coordinate systems.
