# Creating a location provider for ArcGIS Runtime SDK
|
|
|
|
Below is an implementation for use with the [ArcGIS Runtime SDK for .NET](http://developers.arcgis.com/net). Use this location provider on the MapView's LocationDisplay to send it location data from your NMEA device to display your current location on a map.
|
|
|
|
Below is an example implementation of this.
|
|
You can also check out the Desktop Sample app in the [Github Repo]( https://github.com/dotMorten/NmeaParser/blob/main/src/SampleApp.WinDesktop/NmeaProvider.cs) which uses this to display a map.
|
|
|
|
**Usage:**
|
|
```csharp
|
|
NmeaParser.NmeaDevice device = new NmeaParser.NmeaFileDevice("NmeaSampleData.txt");
|
|
mapView.LocationDisplay.LocationProvider = new NmeaLocationProvider(device);
|
|
mapView.LocationDisplay.IsEnabled = true;
|
|
```
|
|
|
|
**NmeaLocationProvider.cs**
|
|
```csharp
|
|
using System;
|
|
using System.Threading.Tasks;
|
|
using Esri.ArcGISRuntime.Geometry;
|
|
using Esri.ArcGISRuntime.Location;
|
|
|
|
namespace NmeaParser.ArcGIS
|
|
{
|
|
public class NmeaLocationProvider : ILocationProvider
|
|
{
|
|
public event EventHandler<LocationInfo> LocationChanged;
|
|
private readonly NmeaParser.NmeaDevice device;
|
|
|
|
public NmeaLocationProvider(NmeaParser.NmeaDevice device)
|
|
{
|
|
this.device = device;
|
|
device.MessageReceived += device_MessageReceived;
|
|
}
|
|
|
|
void device_MessageReceived(object sender, NmeaParser.NmeaMessageReceivedEventArgs e)
|
|
{
|
|
var message = e.Message;
|
|
if (message is NmeaParser.Messages.Rmc rmc && rmc.Active)
|
|
{
|
|
LocationChanged?.Invoke(this, new LocationInfo()
|
|
{
|
|
Course = rmc.Course,
|
|
Speed = rmc.Speed,
|
|
Location = new MapPoint(rmc.Longitude, rmc.Latitude, SpatialReferences.Wgs84)
|
|
});
|
|
}
|
|
}
|
|
|
|
public Task StartAsync() => device.OpenAsync();
|
|
|
|
public Task StopAsync() => device.CloseAsync();
|
|
}
|
|
}
|
|
|
|
```
