/**

 * A 1-dimensional coordinate system used to record the heights or depths of points.

 * Such a coordinate system is usually dependent on the Earth's gravity field, perhaps

 * loosely as when atmospheric pressure is the basis for the vertical coordinate system axis.

 * An exact definition is deliberately not provided as the complexities of the subject fall

 * outside the scope of the ISO 19111 specification.

 *

 * <p>This type of CS can be used by coordinate reference systems of type

 * {@link org.opengis.referencing.crs.VerticalCRS}.

 * The following examples describe some possible axes for vertical CS used with the above-cited CRS:</p>

 *

 * <table class="ogc">

 *   <caption>Example 1: positive values above sea level</caption>

 *   <tr><th>Axis name</th> <th>Abbr.</th> <th>Direction</th> <th>Unit</th></tr>

 *   <tr><td>Gravity-related height</td> <td>H</td> <td>{@link AxisDirection#UP}</td> <td>metre</td></tr>

 * </table>

 *

 * <table class="ogc">

 *   <caption>Example 2: positive values below sea level</caption>

 *   <tr><th>Axis name</th> <th>Abbr.</th> <th>Direction</th> <th>Unit</th></tr>

 *   <tr><td>Depth</td> <td>D</td> <td>{@link AxisDirection#DOWN}</td> <td>metre</td></tr>

 * </table>

 *

 * Note: gvSIG derived these interfaces from GeoAPI in order to have a simpler API and also to

 * avoid namespace collisions (e.g. GeoAPI 3 vs GeoTools interfaces). There is no plans

 * to evolve these interfaces to adapt them to future GeoAPI versions.
