Examples with CSFactory org.opengis.referencing.cs.CSFactory used on opensource projects

Example 1 with CSFactory

use of org.opengis.referencing.cs.CSFactory in project sis by apache.

the class CommonAuthorityFactory method displayCRS.

/**
 * Returns the "Computer display" reference system (CRS:1). This is rarely used.
 */
private synchronized CoordinateReferenceSystem displayCRS() throws FactoryException {
    if (displayCRS == null) {
        final CSFactory csFactory = DefaultFactories.forBuildin(CSFactory.class);

Example 2 with CSFactory

use of org.opengis.referencing.cs.CSFactory in project sis by apache.

the class CRS method compound.

/**
 * Creates a compound coordinate reference system from an ordered list of CRS components.
 * A CRS is inferred from the given components and the domain of validity is set to the
 * {@linkplain org.apache.sis.metadata.iso.extent.DefaultExtent#intersect intersection}
 * of the domain of validity of all components.
 *
 * <div class="section">Ellipsoidal height</div>
 * If a two-dimensional geographic or projected CRS if followed or preceded by a vertical CRS with ellipsoidal
 * {@linkplain org.apache.sis.referencing.datum.DefaultVerticalDatum#getVerticalDatumType() datum type}, then
 * this method combines them in a single three-dimensional geographic or projected CRS.  Note that standalone
 * ellipsoidal heights are not allowed according ISO 19111. But if such situation is nevertheless found, then
 * the action described here fixes the issue. This is the reverse of <code>{@linkplain #getVerticalComponent
 * getVerticalComponent}(crs, true)</code>.
 *
 * <div class="section">Components order</div>
 * Apache SIS is permissive on the order of components that can be used in a compound CRS.
 * However for better inter-operability, users are encouraged to follow the order mandated by ISO 19162:
 *
 * <ol>
 *   <li>A mandatory horizontal CRS (only one of two-dimensional {@code GeographicCRS} or {@code ProjectedCRS} or {@code EngineeringCRS}).</li>
 *   <li>Optionally followed by a {@code VerticalCRS} or a {@code ParametricCRS} (but not both).</li>
 *   <li>Optionally followed by a {@code TemporalCRS}.</li>
 * </ol>
 *
 * @param  components  the sequence of coordinate reference systems making the compound CRS.
 * @return the compound CRS, or {@code components[0]} if the given array contains only one component.
 * @throws IllegalArgumentException if the given array is empty or if the array contains incompatible components.
 * @throws FactoryException if the geodetic factory failed to create the compound CRS.
 *
 * @since 0.8
 *
 * @see GeodeticObjectFactory#createCompoundCRS(Map, CoordinateReferenceSystem...)
