* 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 **magnetic declination** at your current location {{:icon_05.png?nolink}}, which is the difference between the magnetic north and the geographic north.

==== The compass settings ==== | ==== Target and navigation ==== |
| |
Click on the compass "**''Settings''**" {{:icon_06.png?nolink}} button to open the settings dialog. | When a location is set as target, the compass view can be used as a navigation tool, and the following information is given: |
| |
If desired: | * The **name** {{:icon_01.png?nolink}} of the target, if any; |
* Click on the "**''Sensor''**" 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; | * The **direction** {{:icon_02.png?nolink}} of the target, from your current location, pointed by a green arrow; |
* Un-check the "**''Moving rose and graduations''**" check-box to display the compass with a fixed background rose and moving needle. | * 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. |
| |
{{ :en:help:1.4:orientation:compass_needle.jpg?nolink }} | {{: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. |
| |
==== The target finder ==== | 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 "**''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. | {{ :en:help:1.4:orientation:compass_target.jpg?nolink }} |
| |
{{: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. | ==== The compass settings ==== |
| |
It also gives you the following information: | Click on the compass "**''Settings''**" {{:icon_01.png?nolink}} button to open the settings dialog. |
* **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°). | 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}}. |
