    • IDENTIFIER_OF_BASE

      public static final String IDENTIFIER_OF_BASE
      The "9812" EPSG identifier for "Hotine Oblique Mercator (variant A)". Should be preferred to the name when available. The IDENTIFIER_OF_BASE name is for avoiding confusion with the IDENTIFIER name used in subclasses.
