Inter-relate two coordinate systems


This class provides the basic facilities for transforming a set of coordinates (representing " input" points) to give a new set of coordinates (representing " output" points). It is used to describe the relationship which exists between two different coordinate systems and to implement operations which make use of this (such as transforming coordinates and resampling grids of data). However, the Mapping class does not have a constructor function of its own, as it is simply a container class for a family of specialised Mappings which implement particular types of coordinate transformation.

Constructor Function



The Mapping class inherits from the Object class.


In addition to those attributes common to all Objects, every Mapping also has the following attributes:


In addition to those routines applicable to all Objects, the following routines may also be applied to all Mappings:
