-====== Compass ====== 
- 
-The Compass feature uses the magnetic sensor of your device (if available) to give you helpful orientation information. 
- 
-This feature is composed of a sub-menu providing a fast access to few controls and settings, and a dedicated window with more details and information. 
- 
-{{ :​en:​help:​1.4:​orientation:​submenu.jpg?​nolink}}

-  * The "​**''​Rotate the map''​**"​ {{:​icon_05.png?​nolink}} check-box controls either or not to rotate the map based on the compass north to match the real direction you are looking at; 
-  * The "​**''​Current heading''​**"​ {{:​icon_06.png?​nolink}} check-box controls either or not to display an information box {{:​icon_07.png?​nolink}} on the map with your current heading.

-==== The compass view ==== 
- 
-The "​**''​compass view''​**"​ {{:​icon_01.png?​nolink}} is a graphical representation of the true (geographic) north direction, pointed by the red arrow. 
- 
-It also gives you the following information:​ 
-  * The **precise heading** arrow {{:​icon_02.png?​nolink}},​ when this one is between -20° and +20°, including mils graduation; 
-  * The **heading** value {{:​icon_03.png?​nolink}},​ which is the angle between the geographic north and the current direction you are looking at (the direction of your device); 
-  * A **pitch and roll** level {{:​icon_04.png?​nolink}},​ helping you to keep the device flat; 
-  * The **magnetic declination** at your current location {{:​icon_05.png?​nolink}},​ which is the difference between the magnetic north and the geographic north. The application uses either the last known location of your device if any, or the screen center location. This value is computed each time you activate the compass. 
- 
-==== The target finder ==== 
- 
-The "​**''​target finder''​**"​ {{:​icon_04.png?​nolink}} is a graphical representation of the direction toward the targeted waypoint. Once the green arrow is at the center of the target finder, you are currently looking at direction of the target. 
- 
-{{:​icon_help.png?​nolink}} The application uses the screen center location as your current location. You can lock this screen center point on the current GPS location to get updated directions, based on your real location. 
- 
-It also gives you the following information:​ 
-  * **The bearing** {{:​icon_05.png?​nolink}} of the target, in degree, which is the angle between the geographic north and the targeted waypoint, at your current location; 
-  * **The direction** {{:​icon_06.png?​nolink}} of the target, in degree, which is the angle between your current heading and the bearing of the target, at your current location; 
-  * **The distance** {{:​icon_07.png?​nolink}} of the target, from your current location. 
- 
-{{:​icon_help.png?​nolink}} When your heading is equals to the target bearing, it means that you are currently looking at the target direction (direction of 0°).
