In This Topic

Gets an elevation profile calculated between and . Intermediate points are calculated at equal distances between the end points according to the specified. All Z values of the calculated polyline are populated from the Ground Surface Layer. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public ElevationProfileResult GetElevationProfileFromSurface( 
   MapPoint startPoint,
   MapPoint endPoint,
   int numPoints,
   ElevationSurfaceLayer surfaceLayer
)

Public Overloads Function GetElevationProfileFromSurface( _
   ByVal startPoint As MapPoint, _
   ByVal endPoint As MapPoint, _
   ByVal numPoints As Integer, _
   ByVal surfaceLayer As ElevationSurfaceLayer _
) As ElevationProfileResult

Parameters

startPoint: The start point.
endPoint: The end point.
numPoints: The number of points required in the resulting polyline. Note this count includes the start and end points. There must be at least 10 points.
surfaceLayer: Identifies the surface to be used. If null is specified, then the default Ground Surface will be used.

Return Value

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