Module org.opengis.geoapi.example

Package org.opengis.example.parameter

package org.opengis.example.parameter
Implementation of some interfaces from the org.opengis.parameter package. In order to provide a simpler model, the classes in this package implement both GeneralParameterValue and GeneralParameterDescriptor. This means that each parameter value is also its own descriptor.

Example: Creating parameters for the Mercator projection

public ParameterValueGroup createMercatorParameters() {
    final Citation authority = new SimpleCitation("EPSG");
    return new SimpleParameterGroup(authority, "Mercator (variant A)",
            new SimpleParameter(authority, "Latitude of natural origin",     SimpleParameter.Type.LATITUDE),
            new SimpleParameter(authority, "Longitude of natural origin",    SimpleParameter.Type.LONGITUDE),
            new SimpleParameter(authority, "Scale factor at natural origin", SimpleParameter.Type.SCALE),
            new SimpleParameter(authority, "False easting",                  SimpleParameter.Type.LINEAR),
            new SimpleParameter(authority, "False northing",                 SimpleParameter.Type.LINEAR));
}

Example: Defining values to the Mercator parameters

public ParameterValueGroup createMercatorParameters() {
    ParameterValueGroup group = createMercatorParameters();
    group.parameter("Latitude of natural origin").setValue(30.0, NonSI.DEGREE_ANGLE);
    group.parameter("False easting").setValue(5000.0, SI.METRE);
}
