Detailed Description

A collection of two or more geodetic or vertical reference frames (or if not geodetic or vertical reference frame, a collection of two or more datums) which for all but the highest accuracy requirements may be considered to be insignificantly different from each other.

Every frame within the datum ensemble must be a realizations of the same Terrestrial Reference System or Vertical Reference System.

Remarks: Implements DatumEnsemble from ISO 19111:2018

Member Function Documentation

DatumEnsembleNNPtr osgeo::proj::datum::DatumEnsemble::create	(	const util::PropertyMap &	properties,
		const std::vector< DatumNNPtr > &	datumsIn,
		const metadata::PositionalAccuracyNNPtr &	accuracy
	)

static

Instanciate a DatumEnsemble.

Parameters

properties	See General properties. At minimum the name should be defined.
datumsIn	Array of at least 2 datums.
accuracy	Accuracy of the datum ensemble

Returns: new DatumEnsemble.

Exceptions

util::Exception

const std::vector< DatumNNPtr > & osgeo::proj::datum::DatumEnsemble::datums ( ) const

Return the set of datums which may be considered to be insignificantly different from each other.

Returns: the set of datums of the DatumEnsemble.

const metadata::PositionalAccuracyNNPtr & osgeo::proj::datum::DatumEnsemble::positionalAccuracy ( ) const

Return the inaccuracy introduced through use of this collection of datums.

It is an indication of the differences in coordinate values at all points between the various realizations that have been grouped into this datum ensemble.

Returns: the accuracy.
