Detailed Description

The abstract class for all datum converters.

Library: ilvmaps

This class is the base class of all classes providing services to convert coordinates from one horizontal datum to another.

Member Function Documentation

convert()

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.
