    ComputeCombinedScaleFactor Method
    In This Topic
    Compute the combined scale factor using two points and using a z elevation at the mid-point between them.
    Syntax
    public static Task<double> ComputeCombinedScaleFactor( 
       Map map,
       double x1,
       double y1,
       double x2,
       double y2,
       double z
    )
    Public Shared Function ComputeCombinedScaleFactor( _
       ByVal map As Map, _
       ByVal x1 As Double, _
       ByVal y1 As Double, _
       ByVal x2 As Double, _
       ByVal y2 As Double, _
       ByVal z As Double _
    ) As Task(Of Double)

    Parameters

    map
    The map used to calculate the combined scale factor.
    x1
    The x coordinate of the first point.
    y1
    The y coordinate of the first point.
    x2
    The x coordinate of the second point.
    y2
    The y coordinate of the second point.
    z
    The z coordinate.

    Return Value

    A Task returning the calculated combined scale factor.
    Exceptions
    ExceptionDescription
    map is null.
    Remarks
    This extension method for the ArcGIS.Desktop.Mapping.Map class requires a map in a projected coordinate system, and assumes the x,y coordinates are in the map's ArcGIS.Core.Geometry.SpatialReference.Unit and the z coordinate is in the map's ArcGIS.Core.Geometry.SpatialReference.ZUnit. If the map has no ZUnit then the same unit for x,y is used for the z coordinate.
