Dimensionality getDimension() const
Surfaces are 2-dimensional objects.
virtual Surface & operator=(const Surface &rhs)
Assignment operator.
Dimensionality
From Wikipedia: "in mathematics, the dimension of an object is an intrinsic property, independent of the space in which the object may happen to be embedded".
Geometry is the root class of the geometries hierarchy, it follows OGC and ISO standards.
GeomType
Each enumerated type is compatible with a Well-known Binary (WKB) type code.
Surface(GeomType t, int srid=0, Envelope *mbr=0)
It initializes the surface with the specified spatial reference system id and envelope.
virtual Geometry & operator=(const Geometry &rhs)
Assignment operator.
An Envelope defines a 2D rectangular region.
Surface is an abstract class that represents a 2-dimensional geometric objects.
