Detailed Description

The origin meridian from which longitude values are determined.

Note: The default value for prime meridian name is "Greenwich". When the default applies, the value for the longitude shall be 0 (degrees).

Remarks: Implements PrimeMeridian from ISO 19111:2018

Member Function Documentation

PrimeMeridianNNPtr osgeo::proj::datum::PrimeMeridian::create	(	const util::PropertyMap &	properties,
		const common::Angle &	longitudeIn
	)

static

Instanciate a PrimeMeridian.

Parameters

properties	See General properties. At minimum the name should be defined.
longitudeIn	the longitude of the prime meridian.

Returns: new PrimeMeridian.

bool osgeo::proj::datum::PrimeMeridian::isEquivalentTo	(	const util::IComparable *	other,
		util::IComparable::Criterion	criterion = `util::IComparable::Criterion::STRICT`
	)		const

overridevirtual

Returns whether an object is equivalent to another one.

Parameters

other	other object to compare to
criterion	comparaison criterion.

Returns: true if objects are equivalent.

Implements osgeo::proj::util::IComparable.

const common::Angle & osgeo::proj::datum::PrimeMeridian::longitude ( )

Return the longitude of the prime meridian.

It is measured from the internationally-recognised reference meridian ('Greenwich meridian'), positive eastward. The default value is 0 degrees.

Returns: the longitude of the prime meridian.
