ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Desktop.Mapping Namespace / RasterLayer Class / InterpolateShape Method / InterpolateShape(Geometry) Method
The geometry to be interpolated. It must be a point, multipoint, polyline or polygon.

In This Topic
    InterpolateShape(Geometry) Method
    In This Topic
    Interpolates Z values for a geometric shape from the raster layer. Bilinear interpolation is used. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public Geometry InterpolateShape( 
       Geometry geometry
    )
    Public Overloads Function InterpolateShape( _
       ByVal geometry As Geometry _
    ) As Geometry

    Parameters

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

    Return Value

    A ArcGIS.Core.Geometry.Geometry with surface elevation z values.
    Exceptions
    ExceptionDescription
    geometry cannot be null.
    The set of parameters is invalid for this surface. See CanInterpolateShape.
    An exception occurred within the InterpolateShape calculation.
    This method or property must be called within the lambda passed to QueuedTask.Run.
    Remarks
    Portions of the input not falling within the interpolation zone of the surface will be clipped.

    InterpolateShape will handle differences in spatial reference between the input shape and the surface. It will project (a copy of) the input geometry to match the surface for the sake of interpolation. It will then re-project the output geometry so it's the same as the input shape.

    See also InterpolateShape(Geometry,Double) if you wish to specify a specific value for densification of the geometry before interpolation occurs. This method uses the default value for raster based surfaces which is equal to the cellsize.
