Function ConformalProjectionFactors.meridianConvergence

Meridian convergence as a strongly typed angle.

Angle!T meridianConvergence() const pure nothrow @nogc @property @safe;

Example

Example reading meridian convergence. 

import geodesy;
const projection = UtmProjection!double.fromZone(
    wgs84!double(), UtmZone.fromNumber(33), UtmHemisphere.north);
const point = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(48.20849),
    Longitude!double.fromDegrees(16.37208));
const factors = projection.forwardFactors(point);
assert(factors.meridianConvergence.radians
    == factors.meridianConvergence.radians);
