Creating a location provider for ArcGIS Runtime SDK

Below is an implementation for use with the ArcGIS Runtime SDK for .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 which uses this to display a map.

Usage:

NmeaParser.NmeaDevice device = new NmeaParser.NmeaFileDevice("NmeaSampleData.txt");
mapView.LocationDisplay.LocationProvider = new NmeaLocationProvider(device);
mapView.LocationDisplay.IsEnabled = true;

NmeaLocationProvider.cs

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();
    }
}
