ArcGIS.Desktop.Mapping Namespace / Map Class / GetElevationProfileFromSurfaceAsync Method / GetElevationProfileFromSurfaceAsync(IEnumerable<Polyline>) Method
A set of polylines.
Example Version

GetElevationProfileFromSurfaceAsync(IEnumerable<Polyline>) Method
Gets an elevation profile for the specified polylines. All Z values of the calculated polyline are populated from the Ground Surface Layer.
Syntax
public Task<ElevationProfileResult> GetElevationProfileFromSurfaceAsync( 
   IEnumerable<Polyline> polylines
)

Parameters

polylines
A set of polylines.

Return Value

An ElevationProfileResult. If successful, this contains the generated polyline.
Exceptions
ExceptionDescription
polylines cannot be null.
This Map does not have a visible Ground Surface Layer.
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 Elevation profile from the default ground surface
// find the elevation profile for a polyline / set of polylines
var result = await MapView.Active.Map.GetElevationProfileFromSurfaceAsync([lineGeom]);
if (result.Status == SurfaceZsResultStatus.Ok)
{
  var polylineZ = result.Polyline;

  // process the polylineZ
}

// find the elevation profile for a set of points
result = await MapView.Active.Map.GetElevationProfileFromSurfaceAsync(pts);
if (result.Status == SurfaceZsResultStatus.Ok)
{
  var polylineZ = result.Polyline;

  // process the polylineZ
}
