GetDirectionOffset Method

In This Topic

Gets the angle in decimal degrees to be used in ground to grid calculations.

Syntax

C#
Visual Basic (Declaration)

public static double GetDirectionOffset( 
   CIMGroundToGridCorrection c
)

Public Shared Function GetDirectionOffset( _
   ByVal c As CIMGroundToGridCorrection _
) As Double

Parameters

c: A ArcGIS.Core.CIM.CIMGroundToGridCorrection obtained from GetGroundToGridCorrection

Return Value

The DirectionOffset if UsingDirectionOffset is true, otherwise DefaultDirectionOffset if false.

Remarks

This extension method for the ArcGIS.Core.CIM.CIMGroundToGridCorrection class is identical to: c.UsingDirectionOffset() ? c.Direction : DefaultDirectionOffset This method can be used whether or not UsingDirectionOffset is true and returns the default if false.

Example

G2G Settings

CIMGroundToGridCorrection correction = null;
bool isCorecting = correction.IsCorrecting();   // equivalent to correction != null && correction.Enabled;
bool UsingOffset = correction.UsingDirectionOffset();   // equivalent to correction.IsCorrecting() && correction.UseDirection;
double dOffset = correction.GetDirectionOffset(); // equivalent to correction.UsingDirectionOffset() ? correction.Direction : DefaultDirectionOffset;
bool usingDistanceFactor = correction.UsingDistanceFactor();  // equivalent to correction.IsCorrecting() && correction.UseScale;
bool usingElevation = correction.UsingElevationMode(); // equivalent to correction.UsingDistanceFactor() && c.ScaleType == GroundToGridScaleType.ComputeUsingElevation;
bool usingSFactor = correction.UsingConstantScaleFactor();  //; equivalent to correction.UsingDistanceFactor() && correction.ScaleType == GroundToGridScaleType.ConstantFactor;
double dSFactor = correction.GetConstantScaleFactor(); // equivalent to correctionc.UsingDistanceFactor() ? correction.ConstantScaleFactor : DefaultConstantScaleFactor;

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3 or higher.
