GeodeticLength Method (GeometryEngine)

In This Topic

Gets the geodetic length of the input geometry.

Syntax

C#
Visual Basic (Declaration)

public double GeodeticLength( 
   Geometry geometry,
   LinearUnit lengthUnit,
   GeodeticCurveType curveType
)

Public Function GeodeticLength( _
   ByVal geometry As Geometry, _
   ByVal lengthUnit As LinearUnit, _
   ByVal curveType As GeodeticCurveType _
) As Double

Parameters

geometry: The input geometry. Cannot be null and its spatial reference cannot be null.
lengthUnit: The units of the output. If null, then the output is in meters
curveType: The GeodeticCurveType of the segments.

Return Value

The calculated geodetic length in . If is null, then the length is in meters.

If the geometry is empty, then zero is returned.

Exceptions

Exception	Description
System.ArgumentNullException	Geometry is null or geometry's spatial reference is null.
System.NotImplementedException	The method is not implemented for GeometryBag or Multipatch.
System.NotImplementedException	Spatial reference of geometryis an image coordinate system.

Remarks

Geodetic length is calculated by using only the vertices of the geometry and defining the segments between the points as determined by independent of the actual shape of the geometry.

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3.4 or higher.
