~SpatialReferenceSystem()

virtual te::srs::SpatialReferenceSystem::~SpatialReferenceSystem ( )

virtual

Virtual destructor.

Member Function Documentation

getName()

const std::string & te::srs::SpatialReferenceSystem::getName

(

)

const

Returns the SRS name.

getSRID()

void te::srs::SpatialReferenceSystem::getSRID	(	int &	id,
		std::string &	authName
	)		const

Returns SRS integer identification.

Parameters

id	To return the unique id (output);
authName	To return the authority responsible for the id (output).

getUnitName()

const std::string & te::srs::SpatialReferenceSystem::getUnitName

(

)

const

Returns the SRS unit name.

getWKT()

virtual std::string te::srs::SpatialReferenceSystem::getWKT ( ) const

pure virtual

Returns an OGC's WKT representation for the SRS.

The WKT definition based on document "OpenGIS Implementation Specification: Coordinate Transformation Services Revision 1.00 - pages 18 and 19.

Implemented in te::srs::GeographicCoordinateSystem, and te::srs::ProjectedCoordinateSystem.

isGeographic()

virtual bool te::srs::SpatialReferenceSystem::isGeographic ( ) const

pure virtual

Returns true is a geographic coordinate system and false otherwise.

Implemented in te::srs::GeographicCoordinateSystem, and te::srs::ProjectedCoordinateSystem.

setName()

void te::srs::SpatialReferenceSystem::setName

(

const std::string &

name

)

Sets the SRS name.

Parameters

name	the SRS name.

setSRID()

void te::srs::SpatialReferenceSystem::setSRID	(	int	id,
		const std::string &	authName = "EPSG"
	)

Sets the SRS integer identification.

Spatial reference systems can be referred to using a SRID integer, given by an authority, such as the EPSG codes defined by the International Association of Oil and Gas Producers.

Parameters

id	The SRS integer identifier.
authName	The authority responsible for the identifier. Default "EPSG".

setUnitName()

void te::srs::SpatialReferenceSystem::setUnitName

(

const std::string &

name

)

Sets the SRS unit name.

Parameters

name	the SRS unit name.
