ArcGIS.Desktop.Mapping Namespace / Map Class / GetZsFromSurfaceAsync Method / GetZsFromSurfaceAsync(Geometry,ElevationSurfaceLayer) Method
the input geometry
identifies the surface to be used - if specified null, then the default Ground Surface will be used

In This Topic
    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 an Elevation Surface identified by the given surface name.
    Syntax
    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
    ExceptionDescription
    the input geometry is null
    this Map does not have a surface named surfaceName
    this Map does not have a default Ground Surface (when surfaceName is specified null)
    this Map does not have a CIM definition
    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, Windows 8.1
