Azimuth Calculator

Compute the initial compass bearing (azimuth) and great-circle distance from one lat/long point to another.

Frequently Asked Questions

What is an azimuth?

The compass bearing from one point to another, measured clockwise from north (0°-360°).

How is great-circle distance different from straight-line?

Great-circle is the shortest path along the Earth's surface. Straight-line through the planet would be even shorter but useless for navigation.

Why decimal degrees?

Easier than degrees-minutes-seconds for math. 40° 42' 46" N ≈ 40.7128.
