# CLLocationAccuracy

The accuracy of a geographical coordinate.

```
typealias CLLocationAccuracy = Double
```

## Discussion

When reported in a [`CLLocation`](/documentation/CoreLocation/CLLocation) object, accuracy values are the number of meters from the original geographic coordinate that could yield the user’s actual location. When specifying values for the [`desiredAccuracy`](/documentation/CoreLocation/CLLocationManager/desiredAccuracy) property of your [`CLLocationManager`](/documentation/CoreLocation/CLLocationManager) object, use one of the appropriate constants.

## Topics

### Desired Accuracy Constants

[`kCLLocationAccuracyBestForNavigation`](/documentation/CoreLocation/kCLLocationAccuracyBestForNavigation)

The highest possible accuracy that uses additional sensor data to facilitate navigation apps.

[`kCLLocationAccuracyBest`](/documentation/CoreLocation/kCLLocationAccuracyBest)

The best level of accuracy available.

[`kCLLocationAccuracyNearestTenMeters`](/documentation/CoreLocation/kCLLocationAccuracyNearestTenMeters)

Accurate to within ten meters of the desired target.

[`kCLLocationAccuracyHundredMeters`](/documentation/CoreLocation/kCLLocationAccuracyHundredMeters)

Accurate to within one hundred meters.

[`kCLLocationAccuracyKilometer`](/documentation/CoreLocation/kCLLocationAccuracyKilometer)

Accurate to the nearest kilometer.

[`kCLLocationAccuracyThreeKilometers`](/documentation/CoreLocation/kCLLocationAccuracyThreeKilometers)

Accurate to the nearest three kilometers.

[`kCLLocationAccuracyReduced`](/documentation/CoreLocation/kCLLocationAccuracyReduced)

The level of accuracy used when an app isn’t authorized for full accuracy location data.
