Geo::Ellipsoid - Longitude and latitude calculations using an ellipsoid model. River stage one • 2 direct dependents • 2 total dependents

Geo::Ellipsoid performs geometrical calculations on the surface of an ellipsoid. An ellipsoid is a three-dimension object formed from the rotation of an ellipse about one of its axes. The approximate shape of the earth is an ellipsoid, so Geo::Ellips...
