Module geospatial 

Geospatial distance functions: Haversine and Vincenty.

This module provides:

• Haversine: Great-circle distance on a sphere
• Vincenty: Geodesic distance on an ellipsoid
• Geospatial: Blanket trait combining Haversine + Vincenty

Traits

Geospatial

Combined trait for all geospatial distance computations.

Haversine

Computes great-circle distances between geographic coordinates on Earth.

Vincenty

Computes Vincenty geodesic distances on the WGS84 ellipsoid.
