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

C#
Visual Basic (Declaration)

public bool CanInterpolateShape( 
   Geometry geometry
)

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

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.True if checks pass. 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.

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

var tinLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<TinLayer>().FirstOrDefault();
await QueuedTask.Run(() =>
{
  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, Windows 10

ArcGIS Pro version: 3.4 or higher.
