GetSpatialReference Method (SerialPortDeviceLocationSource)

In This Topic

Returns the spatial coordinate system the coordinates will be emitted from a local device such as GPS/GNSS. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public override SpatialReference GetSpatialReference()

Public Overrides Function GetSpatialReference() As SpatialReference

Return Value

A ArcGIS.Core.Geometry.SpatialReference

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run

Example

Get Current Device Location Source and Properties

bool isConnected = DeviceLocationService.Instance.IsDeviceConnected();

var src = DeviceLocationService.Instance.GetSource();

if (src is SerialPortDeviceLocationSource serialPortSrc)
{
  var port = serialPortSrc.ComPort;
  var antennaHeight = serialPortSrc.AntennaHeight;
  var dataBits = serialPortSrc.DataBits;
  var baudRate = serialPortSrc.BaudRate;
  var parity = serialPortSrc.Parity;
  var stopBits = serialPortSrc.StopBits;

  // retrieving spatial reference needs the MCT
  var sr = await QueuedTask.Run(() =>
  {
    return serialPortSrc.GetSpatialReference();
  });

}
var dlProps = DeviceLocationService.Instance.GetProperties();
var accuracy = dlProps.AccuracyThreshold;

Requirements

Target Platforms: Windows 11, Windows 10
