ArcGIS.Core.Geometry Namespace / SpatialReference Class / PositiveDirection Property

In This Topic
    PositiveDirection Property (SpatialReference)
    In This Topic
    Gets the positive direction of the vertical coordinate system.
    Syntax
    public PositiveDirection PositiveDirection {get;}
    Public ReadOnly Property PositiveDirection As PositiveDirection
    Remarks
    The positive direction determines if a positive Z-value represents height (up) or depth (down). If the spatial reference doesn't have a vertical coordinate system, then PositiveDirection.None is returned.

    In a WKT string, the positive direction looks something like "PARAMETER["Direction",1.0]" where 1 is up and -1 is down.
