Function GeodesicInverseResult.distance

Shortest geodesic distance in the same linear unit as the ellipsoid semi-major axis.

T distance() const pure nothrow @nogc @property @safe;

Example

Example reading the inverse geodesic distance. 

import geodesy;
const solver = Geodesic!double.fromEllipsoid(wgs84!double());
const start = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(48.20849),
    Longitude!double.fromDegrees(16.37208));
const end = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(47.07071),
    Longitude!double.fromDegrees(15.43950));
const result = solver.inverse(start, end);
assert(result.distance > 0.0);
