public class SpatialReferenceIGNFCRSAuthorityFactory
extends SpatialReferenceCRSAuthorityFactory

A CRSAuthorityFactory that request Coordinates References System from the spatialreference.org for the authority Institut national de l'information Géographique et Forestiere (IGN). This factory can process coordinates reference system with code "IGNF:XXXX".

Constructor Details

SpatialReferenceIGNFCRSAuthorityFactory

public SpatialReferenceIGNFCRSAuthorityFactory()

Create a new spatialreference.org CRS factory for IGNF authority.

Method Details

getDefault

public static org.geotools.api.referencing.crs.CRSAuthorityFactory getDefault()
                                                                       throws IOException

Returns a default coordinate system factory backed by the spatialreference.org website.

Returns:

The default factory.

Throws:

IOException - if the connection to the spatialreference.org website cannot be established.

getAuthority

public org.geotools.api.metadata.citation.Citation getAuthority()

getAuthorityCodes

public Set<String> getAuthorityCodes(Class clazz)
                              throws org.geotools.api.referencing.FactoryException

Returns the set of authority codes of the given type. The type argument specify the base class. For example if this factory is an instance of CRSAuthorityFactory, then:

• CoordinateReferenceSystem.class asks for all authority codes accepted by createGeographicCRS, createProjectedCRS, createVerticalCRS, createTemporalCRS and their friends.
• ProjectedCRS.class asks only for authority codes accepted by createProjectedCRS.

The following implementaiton filters the set of codes based on the "PROJCS" and "GEOGCS" at the start of the WKT strings. It is assumed that we only have GeographicCRS and ProjectedCRS's here.

Parameters:

clazz - The spatial reference objects type (may be Object.class).

Returns:

The set of authority codes for spatial reference objects of the given type. If this factory doesn't contains any object of the given type, then this method returns an empty set.

Throws:

org.geotools.api.referencing.FactoryException - if access to the underlying database failed.
