GetZsFromSurfaceAsync(Geometry) Method

In This Topic

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

Syntax

C#
Visual Basic (Declaration)

public Task<SurfaceZsResult> GetZsFromSurfaceAsync( 
   Geometry geometry
)

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

Parameters

geometry: the input geometry

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 a Ground Surface Layer
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, then the corresponding output geometry point Z will be set to the value specified in SurfaceZsMissingHandler.DefaultOutputZ.

Example

Get Z values from a surface

var geometry = await QueuedTask.Run<Geometry>(() =>
{
  Geometry mapCentergeometry = MapView.Active.Map.CalculateFullExtent().Center;
  return mapCentergeometry;
});
//Pass any Geometry type to GetZsFromSurfaceAsync
var surfaceZResult = await MapView.Active.Map.GetZsFromSurfaceAsync(geometry);
return surfaceZResult;

Requirements

Target Platforms: Windows 11, Windows 10, Windows 8.1
