Method Detail

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 specification:
"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 the toBase() method name. By analogy with 01-009, GeoAPI defines a method name which contains the "FromBase" expression.
