GetElevationProfileFromSurface(IEnumerable<Polyline>,ElevationSurfaceLayer,SurfaceZsMissingHandler) Method

In This Topic

Gets an elevation profile for the specified polylines. All Z values of the calculated polyline are populated from the specified Elevation Surface Layer.

Syntax

C#
Visual Basic (Declaration)

public ElevationProfileResult GetElevationProfileFromSurface( 
   IEnumerable<Polyline> polylines,
   ElevationSurfaceLayer surfaceLayer,
   SurfaceZsMissingHandler missingHandler
)

Public Overloads Function GetElevationProfileFromSurface( _
   ByVal polylines As IEnumerable(Of Polyline), _
   ByVal surfaceLayer As ElevationSurfaceLayer, _
   ByVal missingHandler As SurfaceZsMissingHandler _
) As ElevationProfileResult

Parameters

polylines: A set of polylines.
surfaceLayer: Identifies the surface to be used. If null is specified, then the default Ground Surface will be used.
missingHandler: provides options to handle missing Zs in the surface

Return Value

An ElevationProfileResult. If successful, this contains the generated polyline.

Exceptions

Exception	Description
System.ArgumentNullException	polylines cannot be null.
System.ArgumentException	This Map does not have the specified surfaceLayer.
System.ArgumentException	This Map does not have a visible Ground Surface Layer.

Remarks

The missingHandler will be used to determine what to do if the surface has no data at a particular input geometry point. The corresponding output geometries point or vertex Zs will be set to the value specified in the provided missingHandler.OutputZ property. The missingHandler.OnlyProcessMissingZs parameter can be used to overwrite all Z values or only those that are designated as missing based on a comparison with the InputZ value.

Requirements

Target Platforms: Windows 11, Windows 10
