Detailed Description

This class implements an IlvHorizontalDatumConverter using the Molodensky formula.

Library: ilvmaps

This class can convert coordinates from one IlvHorizontalShiftDatum to another. The conversion algorithm uses the Molodensky formula.

Member Function Documentation

convert()

virtual IlvMapsError IlvMolodenskyConverter::convert ( const IlvHorizontalDatum *  sourceDatum, const IlvHorizontalDatum *  targetDatum, IlvCoordinate &  ll  ) const

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.

Implements IlvHorizontalDatumConverter.
