Distance Calculator
Calculate geodesic distance between two points.
How to use
- Enter Point A and Point B (longitude/latitude).
- Read the geodesic distance, initial/final bearing, and midpoint.
- Batch tab: measure the distance from many CSV points to one fixed reference point at once.

Distance Calculation Coverage
Computes the geodesic (great-circle) distance between two longitude/latitude points, along with initial/final bearing and the midpoint — using turf's spherical calculation on WGS84, not a flat-plane approximation.
The Batch tab measures the distance from many CSV points to one fixed reference point at once.
How to use it
- Enter the two coordinates.
- Read the distance, bearing, and midpoint.
- To compare many points against one reference, upload a CSV in the Batch tab.
Frequently asked questions
Is this a straight line through the earth?
No — it's the great-circle (geodesic) distance along the surface, the same figure a flight-distance calculator reports.
Can I measure many points against one reference at once?
Yes — the Batch tab takes a CSV of points and computes each one's distance to a single fixed reference point.
