Examples

This example shows how to use the Geolocator class to retrieve the device's location. For more info, see Get current location.

using Windows.Devices.Geolocation;
...
var accessStatus = await Geolocator.RequestAccessAsync();
switch (accessStatus)
{
    case GeolocationAccessStatus.Allowed:
        // notify user: Waiting for update

        // If DesiredAccuracy or DesiredAccuracyInMeters are not set (or value is 0), DesiredAccuracy.Default is used.
        Geolocator geolocator = new Geolocator { DesiredAccuracyInMeters = _desireAccuracyInMetersValue };

        // Subscribe to StatusChanged event to get updates of location status changes
        _geolocator.StatusChanged += OnStatusChanged;

        // Carry out the operation
        Geoposition pos = await geolocator.GetGeopositionAsync();

        UpdateLocationData(pos);
        // notify user: Location updated
        break;

    case GeolocationAccessStatus.Denied:
        // notify user: Access to location is denied

        break;

    case GeolocationAccessStatus.Unspecified:
        // notify user: Unspecified error
        break;
}

Remarks

Version history

Windows version	SDK version	Value added
1607	14393	AllowFallbackToConsentlessPositions
1607	14393	DefaultGeoposition
1607	14393	IsDefaultGeopositionRecommended

Constructors

Geolocator()

Initializes a new Geolocator object.

Properties

DefaultGeoposition	Gets the location manually entered into the system by the user, to be utilized if no better options exist.
DesiredAccuracy	The accuracy level at which the Geolocator provides location updates.
DesiredAccuracyInMeters	Gets or sets the desired accuracy in meters for data returned from the location service.
IsDefaultGeopositionRecommended	Indicates whether the user should be prompted to set a default location manually.
LocationStatus	The status that indicates the ability of the Geolocator to provide location updates.
MovementThreshold	The distance of movement, in meters, relative to the coordinate from the last PositionChanged event, that is required for the Geolocator to raise a PositionChanged event.
ReportInterval	The requested minimum time interval between location updates, in milliseconds. If your application requires updates infrequently, set this value so that location services can conserve power by calculating location only when needed.

Methods

AllowFallbackToConsentlessPositions()	Sets the Geolocator to use coarse location as a fallback option (see Remarks).
GetGeopositionAsync()	Starts an asynchronous operation to retrieve the current location of the device.
GetGeopositionAsync(TimeSpan, TimeSpan)	Starts an asynchronous operation to retrieve the current location of the device.
GetGeopositionHistoryAsync(DateTime)	Starts an asynchronous operation to retrieve the location history of the device. Note This API is not available to all Windows apps. Unless your developer account is specially provisioned by Microsoft, calls to these APIs will fail at runtime.
GetGeopositionHistoryAsync(DateTime, TimeSpan)	Starts an asynchronous operation to retrieve the location history of the device. Note This API is not available to all Windows apps. Unless your developer account is specially provisioned by Microsoft, calls to these APIs will fail at runtime.
RequestAccessAsync()	Requests permission to access location data.

Events

PositionChanged	Raised when the location is updated.
StatusChanged	Raised when the ability of the Geolocator to provide updated location changes.
