CanInterpolateShape Method (TinLayer)

In This Topic

Determines if values can be interpolated for the given geometry. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

Visual Basic (Declaration)
C#

Public Function CanInterpolateShape( _
   ByVal geometry As Geometry _
) As Boolean

public bool CanInterpolateShape( 
   Geometry geometry
)

Parameters

geometry: The geometry to be interpolated. It must be a point, multipoint, polyline or polygon.

Return Value

True if the shape can be interpolated. False otherwise.

Remarks

It is important to call this method prior to InterpolateShape(Geometry,SurfaceInterpolationMethod) or InterpolateShape(Geometry,SurfaceInterpolationMethod,Double,Double) to ensure that a possible result can be found given the set of input parameters.

This method also checks for a 3D Analyst license which is required to perform the analysis.

Note that if this method returns true it does not preclude the InterpolateShape method from throwing an exception due to a calculation error and callers should code defensively and use appropriate exception handling.

Example

Interpolate Shape

{
  // Note: Needs QueuedTask to run
  // Note: Needs 3d Analyst license to run
  {
    ArcGIS.Core.Geometry.Geometry output = null;
    // interpolate z values for a geometry
    if (tinLayer.CanInterpolateShape(polyline))
      output = tinLayer.InterpolateShape(polyline, SurfaceInterpolationMethod.NaturalNeighbor);

    if (output != null)
    {
      // process the output
    }

    // densify the shape before interpolating
    if (tinLayer.CanInterpolateShape(polygon))
      output = tinLayer.InterpolateShape(polygon, SurfaceInterpolationMethod.Linear, 0.01, 0);

    if (output != null)
    {
      // process the output
    }
  }
}

Requirements

Target Platforms: Windows 11 Home, Pro, Enterprise (64 bit)

ArcGIS Pro version: 3.4 or higher.
