Vertical points
===============

Height <=> Depth reversal
-------------------------

.. code-block:: php

    $point = VerticalPoint::create(...);
    $newPoint = $point->heightDepthReversal(
        Vertical $to
    ); // returns a new VerticalPoint

Offset
------

.. code-block:: php

    $point = VerticalPoint::create(...);
    $newPoint = $point->offset(
        Vertical $to,
        Length $verticalOffset
    ); // returns a new VerticalPoint

Offset and Slope
----------------

.. code-block:: php

    $point = VerticalPoint::create(...);
    $newPoint = $point->offsetAndSlope(
        Vertical $to,
        Angle $ordinate1OfEvaluationPoint,
        Angle $ordinate2OfEvaluationPoint,
        Length $verticalOffset,
        Angle $inclinationInLatitude,
        Angle $inclinationInLongitude,
        GeographicPoint $horizontalPoint
    ); // returns a new VerticalPoint

Offset From Grid File
---------------------

.. code-block:: php

    $point = VerticalPoint::create(...);
    $newPoint = $point->offsetFromGrid(
        Vertical $to,
        GeographicGeoidHeightGrid $offsetsFile,
        bool $inReverse,
        GeographicPoint $horizontalPoint
    ); // returns a new VerticalPoint

Zero-tide height to mean-tide height (EVRF2019)
-----------------------------------------------

.. code-block:: php

    $point = VerticalPoint::create(...);
    $newPoint = $point->zeroTideHeightToMeanTideHeightEVRF2019(
        Vertical $to,
        bool $inReverse,
        GeographicPoint $horizontalPoint
    ); // returns a new VerticalPoint
