@UML(identifier="SC_GeneralDerivedCRS",
specification=ISO_19111)
public interface GeneralDerivedCRS
extends SingleCRS
A coordinate reference system that is defined by its coordinate
conversion from another coordinate reference system
(not by a datum).

Method Details
-
getBaseCRS
@UML(identifier="baseCRS", obligation=MANDATORY, specification=ISO_19111) CoordinateReferenceSystem getBaseCRS()Returns the base coordinate reference system.- Returns:
- The base coordinate reference system.
-
getConversionFromBase
@UML(identifier="conversion", obligation=MANDATORY, specification=ISO_19111) Conversion getConversionFromBase()Returns the conversion from the base CRS to this CRS.- Returns:
- The conversion from the base CRS.
- Departure from OGC/ISO abstract specification:
Change of name without change in functionality
"conversion
" may be confusing as a method name since it does not indicate which CRS is the source or which is the target. OGC document 01-009 used thetoBase()
method name. By analogy with 01-009, GeoAPI defines a method name which contains the "FromBase
" expression.
