virtual IlvMapsError IlvHorizontalDatumConverter::convert	(	const IlvHorizontalDatum *	sourceDatum,
		const IlvHorizontalDatum *	targetDatum,
		IlvCoordinate &	ll
	)			const [pure virtual]

Converts the ll coordinates expressed in sourceDatum to coordinates in targetDatum.

Converts the ll coordinates representing a geodetic latitude and longitude expressed in the sourceDatum horizontal datum, into a coordinate representing the geodetic latitude and longitude, expressed in the targetDatum horizontal datum.

Parameters:

	sourceDatum	Datum in which the input coordinates are expressed.
	targetDatum	Datum in which the input coordinates are converted.
	ll	Coordinates, in radian (ll.x = longitude, ll.y = latitude). After the call, this IlvCoordinate holds the result.

Returns:

IlvMaps::NoError() if the conversion is successful.

Implemented in IlvMolodenskyConverter.
