Interface GeneralDerivedCRS

All Superinterfaces:

CoordinateReferenceSystem, Info, ReferenceSystem

All Known Subinterfaces:

DerivedCRS, ProjectedCRS

public interface GeneralDerivedCRS

extends CoordinateReferenceSystem

A coordinate reference system that is defined by its coordinate conversion from another coordinate reference system (not by a datum).

Version:

Abstract specification 2.0

Author:

ISO 19111, OpenGIS® consortium

UML identifier (abstract type): SC_GeneralDerivedCRS

Method Summary

CoordinateReferenceSystem	getBaseCRS() Returns the base coordinate reference system.
Conversion	getConversionFromBase() Returns the conversion from the base CRS to this CRS.

Method Detail

getBaseCRS

CoordinateReferenceSystem getBaseCRS()

Returns the base coordinate reference system.

Returns:

The base coordinate reference system.

UML identifier (association): baseCRS

getConversionFromBase

Conversion getConversionFromBase()

Returns the conversion from the base CRS to this CRS.

Returns:

The conversion to this CRS.

UML identifier (association): definedByConversion

Name change from the UML:

definedByConversion may be a precise description of the association, but is confusing as a method name. OGC document 01-009 used toBase() method name. By analogy with 01-009, this new interface specifies a method name which contains the FromBase words.
