Function Geodesic.inverse

Solve the shortest inverse geodesic problem with throwing semantics.

GeodesicInverseResult!T inverse(
  const GeographicCoordinate!T start,
  const GeographicCoordinate!T end
) const @safe;

Parameters

NameDescription
start Geographic start position.
end Geographic endpoint.

Returns

Distance plus initial and final forward azimuths.

Throws

GeodesyValueException when the solver is invalid or no finite representable inverse solution can be produced.

Example

Example solving the inverse geodesic problem. 

import geodesy;
const solver = Geodesic!double.fromEllipsoid(wgs84!double());
const vienna = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(48.20849),
    Longitude!double.fromDegrees(16.37208));
const graz = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(47.07071),
    Longitude!double.fromDegrees(15.43950));
const result = solver.inverse(vienna, graz);
assert(result.distance > 100_000.0);
