Detailed Description

This abstract class is the superclass of all concrete SRS classes.

SRS stands for Spatial Reference System, it describes the space and coordinate system in which positions are expressed. Reference counted.

Constructor & Destructor Documentation

VgEngine::VgSRS::VgSRS ( )

protected

This class constructor is protected to prevent direct instantiation.

virtual VgEngine::VgSRS::~VgSRS ( )

protectedpure virtual

Class destructor.

It is pure virtual to force subclasses to reimplement it.

bool VgEngine::VgSRS::isGeoReferenced ( ) const

Returns: True if this is a georeferenced SRS, false if it is a custom SRS, i.e a reference system where coordinates cannot be reprojected into a geographic reference system like WGS84.
