Member Function Documentation

getDatum()

const Datum * te::srs::GeographicCoordinateSystem::getDatum

(

)

const

Returns the associated Datum.

Returns

A pointer to the GEOGCS datum. Class maintains the pointer ownership.

getName()

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

inherited

Returns the SRS name.

getPrimem()

double te::srs::GeographicCoordinateSystem::getPrimem

(

)

const

Returns the meridian used to take longitude measurements from.

getSRID()

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

inherited

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

inherited

Returns the SRS unit name.

getWKT()

std::string te::srs::GeographicCoordinateSystem::getWKT ( ) const

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.

Implements te::srs::SpatialReferenceSystem.

isGeographic()

bool te::srs::GeographicCoordinateSystem::isGeographic ( ) const

virtual

Returns true is a geographic coordinate system and false otherwise.

Implements te::srs::SpatialReferenceSystem.

setDatum()

void te::srs::GeographicCoordinateSystem::setDatum

(

Datum *

datum

)

Sets the associated Datum.

Parameters

datum

Pointer to GEOGCS datum. Do not pass null. Class takes the pointer ownership.

setName()

void te::srs::SpatialReferenceSystem::setName ( const std::string &  name )

inherited

Sets the SRS name.

Parameters

name	the SRS name.

setPrimem()

void te::srs::GeographicCoordinateSystem::setPrimem

(

double

primen

)

Sets the meridian used to take longitude measurements from.

Parameters

primen

The meridian used to take longitude measurements from.

setSRID()

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

inherited

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 )

inherited

Sets the SRS unit name.

Parameters

name	the SRS unit name.
