GetZsFromSurfaceAsync(Geometry,ElevationSurfaceLayer) Method

In This Topic

Obtains a geometry that is similar to the given input geometry, where all Z values are populated from the specified Elevation Surface Layer.

Syntax

C#
Visual Basic (Declaration)

public Task<SurfaceZsResult> GetZsFromSurfaceAsync( 
   Geometry geometry,
   ElevationSurfaceLayer surfaceLayer
)

Public Overloads Function GetZsFromSurfaceAsync( _
   ByVal geometry As Geometry, _
   ByVal surfaceLayer As ElevationSurfaceLayer _
) As Task(Of SurfaceZsResult)

Parameters

geometry: the input geometry
surfaceLayer: Identifies the surface to be used - if specified null, then the default Ground Surface will be used

Return Value

A result that contains a status, plus an output geometry only if the status is favorable

Exceptions

Exception	Description
System.ArgumentNullException	The input geometry is null.
System.ArgumentException	This Map does not have the specified surfaceLayer.
System.ArgumentException	This Map does not have a default Ground Surface (when surfaceLayer is null)
System.InvalidOperationException	This Map does not have a CIM definition.
System.InvalidOperationException	This Map does not have any surfaces.

Remarks

If the surface has no data at a particular input geometry point or vertex, then the corresponding output geometry point or vertex Z will be set to the value specified in SurfaceZsMissingHandler.DefaultOutputZ.

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3 or higher.
