Class Services

  • public final class Services
extends java.lang.Object
    Default implementations of referencing services backed by PROJ4J. Those services are accessible by ServiceLoader, which should be used by implementation-neutral applications. This class provides shortcuts for the convenience of applications that do not need implementation neutrality.

      • createCRS

        public static org.opengis.referencing.crs.CoordinateReferenceSystem createCRS​(java.lang.String code)
                                                                       throws org.opengis.util.FactoryException
        Creates a coordinate reference system from the given authority code. The argument should be of the form "AUTHORITY:CODE". If the authority is unspecified, then "EPSG" is assumed.
        Parameters:
        code - the authority code
        Returns:
        coordinate reference system for the given code
        Throws:
        org.opengis.referencing.NoSuchAuthorityCodeException - if the specified code was not found
        org.opengis.util.FactoryException - if the object creation failed for some other reason

        Creates a coordinate operation between the given pair of coordinate reference systems.
        Parameters:
        source - input coordinate reference system
        target - output coordinate reference system
        Returns:
        a coordinate operation from source to target
        Throws:
        org.opengis.util.FactoryException - if the coordinate operation cannot be created
