A Spatial Reference System, also known as a Coordinate System.
A spatial reference system (SRS) or coordinate reference system (CRS) is a coordinate-based local, regional or global system used to locate geographical entities.

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

pure virtual |
Returns true is a geographic coordinate system and false otherwise.
Implemented in te::srs::ProjectedCoordinateSystem, and te::srs::GeographicCoordinateSystem.
void te::srs::SpatialReferenceSystem::setName | ( | const std::string & | name | ) |
Sets the SRS name.

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