    Purpose of use
    Planning a Garden. To discover the maximum height that a hedge could be grown .... affecting hedge plant choice. The potential east-west hedge would lie a few meters distance on the north side of an existing east-west running wall. The mission is to grow the hedge without adding to existing wall-shaded area to the north side.

    Comment/Request
    Thanks for this easy-to-use calculator.
    Calculation based on height of eye.
    Allow user to input altitude, using information such as the height of a mountain peak, etc, which are generally given in height above sea level.

    For example:
    "The upper station is located at Storsteinen, a mountain ledge about 420 m above sea-level"
