-====== Orientation and 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}}

-To turn on the compass feature, you can either: 
-  * Long-press the "**''Compass''**" menu button {{:icon_01.png?nolink}}; 
-  * Click on the sub-menu toggle {{:icon_03.png?nolink}}.

-===== The Compass sub-menu ===== 
- 
-Click on the "''**Compass**''" {{:icon_01.png?nolink}} menu button to display the sub-menu, composed of the following items: 
-  * The "**''Compass details''**" {{:icon_02.png?nolink}} button opens the compass details window; 
-  * The "**''Compass toggle''**" {{:icon_03.png?nolink}} lets you turn on or off the compass feature easily; 
-  * The "**''Display compass''**" {{:icon_04.png?nolink}} check-box controls either or not to display a compass {{:icon_08.png?nolink}} on the map; 
-  * 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. 
- 
-{{:icon_help.png?nolink}} You can un-check both "**''Display compass''**" and "**''Rotate the map''**" check-boxes to display a small current heading arrow {{:icon_09.png?nolink}}.

- 
-==== 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. 
- 
- 
-==== Target and navigation ==== 
- 
-When a location is set as target, the compass view can be used as a navigation tool, and the following information is given: 
- 
-  * The **name** {{:icon_01.png?nolink}} of the target, if any; 
-  * The **direction** {{:icon_02.png?nolink}} of the target, from your current location, pointed by a green arrow; 
-  * The **absolute bearing** {{:icon_03.png?nolink}} of the target, which is the angle between the geographic north and the target, at your current location; 
-  * The **distance** {{:icon_04.png?nolink}} of the target, from your current location. 
- 
-{{:icon_help.png?nolink}} All these figures are computed from the map center location. Be sure that it's correctly located on your current location, either by moving the map manually or by locking the GPS location on it. 
- 
-When you move towards one direction, be sure to orientate your device correctly so that the **lubber line** {{:icon_05.png?nolink}} matches your forward direction. In this case: 
-  * The azimuth value displayed under the lubber line is your **heading** {{:icon_06.png?nolink}}; 
-  * The **relative bearing** {{:icon_07.png?nolink}} of the target is displayed, which is the angle between your heading and the bearing of the target, at your current location.

- 
-==== The Compass settings ==== 
- 
-Click on the compass "**''Settings''**" {{:icon_01.png?nolink}} button to open the settings dialog. 
- 
-If desired: 
-  * Click on the "**''Sensor''**" {{:icon_02.png?nolink}} list to request orientation updates from another sensor, if your devices has various sensors. Depending on the device, each sensor can be more or less precise, responsible and noisy; 
-  * Un-check the "**''Moving rose and graduations''**" {{:icon_03.png?nolink}} check-box to display the compass with a fixed background rose and moving needle {{:icon_04.png?nolink}}.
