how to get bearing between two point in ArcGIS .Net SDK

SatyaraySingh

I'm trying to find the bearing between two points. Even though we have a property as CurrentBearing in stop-class, it shows NaN if you create the object Stop using any MapPoint. For example

var PointA = new MapPoint(-117.85, 32.20, SpatialReferences.Wgs84);

var StopA= new Stop(PointA);

So if we use StopA.CurrentBearing it will show as NaN.

I just want to find a Bearing value. is there any way I can find the value in .net SDK or do I have to calculate it manually?

You want to use the Geometry Engine to do a DistanceGeodesic - this will return the distance as well as the bearing:

It gives always 0. I'm not sure what I did wrong.

var ConvergenceAngle = SpatialReferences.Wgs84.GetConvergenceAngle(MapPoint)

This is great - I totally missed that this was added way back at 100.3 and have been using a separate WMM implementation to calculate magnetic declination. Do you know if this is using the NGS COF data and updated as they release adjustments/updates?

Hi @MichaelDavis3 - I think that theGetConvergenceAngle method on SpatialReference could be helpful here in figuring out a difference between True North and Grid North for a specific point: https://developers.arcgis.com/net/api-reference/api/net/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Geometry.SpatialReference.GetConvergenceAngle.html

Thank You, It works for me.

Just an Addition to it. If I needed to find bearing from True North to a particular Mappoint. is there any method to do so?
