ElevationProfileGraph Class

In This Topic

Represents an elevation profile graph that is displayed on a mapView. Use MapView.GetElevationProfileGraph to retrieve the elevation profile graph. This may return null if no elevation profile graph is visible. Use one of the MapView.ShowElevationProfileGraph methods to generate a profile graph along a linear path. The profile is calculated using the ground elevation surface in the map.

Object Model

Syntax

C#
Visual Basic (Declaration)

public class ElevationProfileGraph

Public Class ElevationProfileGraph

Remarks

Use MapView.ElevationProfileGraphAdded and MapView.ElevationProfileGraphRemoved to determine when the graph is displayed or removed from the mapView. The profile calculation begins once the graph is displayed. Use ContentLoaded to determine when the profile calculation has finished. Once the calculation has been completed, retrieve the elevation profile information using the Geometry and ElevationProfileStatistics methods.

Elevation profile graphs are temporary and are not saved with the project.
Save the elevation profile information by exporting the profile graph as an image file, or the elevation profile data in table format or as a row or feature in the geodatabase.

Example

Access the ElevationProfileGraph when added

public void ElevationProfileGraphAdded()
{

  var mv = MapView.Active;
  // subscribe to the Added, Removed events for the elevation profile graph
  mv.ElevationProfileGraphAdded += Mv_ElevationProfileGraphAdded;
  mv.ElevationProfileGraphRemoved += Mv_ElevationProfileGraphRemoved;

}

private void Mv_ElevationProfileGraphRemoved(object sender, EventArgs e)
{
  ;
}

private void Mv_ElevationProfileGraphAdded(object sender, EventArgs e)
{
  // get the elevation profile graph from the view
  // this will be non-null since we are in a ElevationProfileGraphAdded handler
  var mv = MapView.Active;
  var graph = mv.GetElevationProfileGraph();

  // subscribe to the ContentLoaded event
  graph.ContentLoaded += Graph_ContentLoaded;
}

private void Graph_ContentLoaded(object sender, EventArgs e)
{
  // get the elevation profile graph
  var graph = sender as ArcGIS.Desktop.Mapping.ElevationProfileGraph;

  // get the elevation profile geometry
  var polyline = graph.Geometry;
  // get the elevation profile statistics
  var stats = graph.ElevationProfileStatistics;
}

Access the ElevationProfileGraph

var elevProfileGraph = MapView.Active.GetElevationProfileGraph();
// Elevation profile graph will be null if no profile graph is displayed
if (elevProfileGraph == null)
  return;

// get the elevation profile geometry and stats
var polyline = elevProfileGraph.Geometry;
var stats = elevProfileGraph.ElevationProfileStatistics;

// reverse the graph
elevProfileGraph.IsReversed = !elevProfileGraph.IsReversed;

// collapse the graph
elevProfileGraph.IsExpanded = false;
