Active outdoor recreation has recently become very popular, more and more people prefer various activities to the banal consumption of cholesterol and alcohol. At the same time, most of these entertainments or competitions (hiking, quest, hiking competitions) require the ability of participants to navigate the terrain. In addition, this knowledge can help save life and health in an extreme situation.

The simplest thing he can do Compass app for iPhone is to determine the direction to the north. Many people who have not encountered the problem of orientation naively believe that, if necessary, they can easily recognize the cardinal points by the moss on the trees or the sloping side of the anthill, but in practice this is extremely difficult to do. As for the compass on your smartphone, it will easily show you the right direction if you even looked at the map out of the corner of your eye before going out into an unfamiliar forest or mountain range.
The second important function of the compass is to determine the bearing. In theory, azimuth is the angle between the north and the target, in practice it is a specific indication of movement. Below we will figure out how to determine the bearing using the map and how to subsequently follow it using the iPhone.

How to determine the bearing on the map using the iPhone and the Compass app
Let’s analyze the following situation – you need to coordinate the actions of a group that must move from checkpoint A to checkpoint B at a distance of 1.5 km. You have a map of the area on which the objects you are looking for are marked, as well as an iPhone with a standard Compass application (it works even in Airplane Mode). We perform the following algorithm of actions:
one. We put the iPhone on the map so that the right side of the smartphone connects the necessary checkpoints;
2. We expand the map so that the north arrow on the compass and the north-south lines on the map are parallel;
3. At the bottom of the screen, the desired azimuth will be displayed in numbers (in our case, 150º).

How to navigate iPhone Compass knowing bearing and distance
Now that the azimuth (150º) and distance (1.5 km) data are available, you can start moving, for this:
one. Align the zero value of the angular scale (vertical dash on top) and the north arrow in the Compass application on the iPhone;
2. Tap the compass face and rotate iPhone to the value of the angle of the specified azimuth (the angle of deviation will be highlighted in red).
3. Follow the direction of the dash from above (in our case 150º) for a given distance (in our case 1.5 km)
In such a simple way, knowing the distance to the checkpoint (in our case, 1.5 km) and determining the direction, the group will easily reach the desired point.
