Compass vs Star Tracker

That you know exactly where you are you get the street address, the exact GPS coordinates and the current height above sea level displayed. In addition, the position is displayed in What3Words (w3w) coordinates. To switch between satellite image and map view just tap the compass. You can zoom with the pinch-/spread Gesture or with the slider beneath the Address so that you can orient yourself at certain prominent points. The blue highlighted area indicates the current accuracy. Terms of Use : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
