Class Services

java.lang.Object
org.locationtech.proj4j.geoapi.Services
public final class Services extends 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(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

    • findOperation

      public static org.opengis.referencing.operation.CoordinateOperation findOperation(org.opengis.referencing.crs.CoordinateReferenceSystem source, org.opengis.referencing.crs.CoordinateReferenceSystem target) throws org.opengis.util.FactoryException
      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
