Horizon Explorer funktioniert nicht

Point your camera at a hill, village, lake or landmark and Horizon Explorer will tell you what you are looking at, how far away it is, and show you a map, and information about the point you're aiming at.  Tracking works best on top of a hill with an unobstructed view of your surroundings (close up trees, buildings, rocks etc. can confuse the tracking).  Fly up high and see the terrain laid out below you to see what is over the hills around you, and get the lay of the land, then see the scale-model 3D map that you can walk around & explore to find out what's behind hills, or investigate up close.  You can drag the terrain with your finger to line up with the camera if the automatic tracking is not working very well.  Horizon Explorer shows you the horizon and skyline around you & tells you what you're looking at.  ARKit technology makes the labels and alignment much more stable than used to be possible.  Or try waving your phone around in the air in a figure 8 to calibrate the compass.
