 +===== Geographic Coordinates =====
  
 +Aerofly FS uses a geographic coordinate system for the scenery.
 +
 +You can display coordinates of your aircraft position in the simulator by pressing Ctrl+F1. The location will be shown in the debug output overlay.
 +
 +Coordinates are defined in the format Lon/Lat. Altitudes or elevations are defined in meters.
 +
 +Lon - Longitude is positive towards East, negative towards West\\
 +Lat - Latitude is positive towards North, negative towards South.
 +
 +==== Finding the Geographic Coordinates ====
 +
 +A small excursion to geographic coordinates...
 +
 +If you want to describe any position on earth in a unified system you may use geographic coordinates (as Aerofly FS 2 does). 
 +We need 360 degrees to do a full circle, so the earth simplified as a bowl consists of 360 longitude lines. Longitude 0 is defined  through Greenwich, negative to the west  and positive to the east. They meet again at the opposite side of the earth at -180/+180 degrees. 
 +It is half of a circle going from north pole to south pole. So lat +90 is the north pole, 0 is the equator line, -90 is the south pole.

 +
 +**Note** - Make sure that you take the sequence into account: Both ways **Lat/Lon** and **Lon/Lat** are common. (Aerofly FS 2 uses Lon/Lat so for example 10°E and 30°N and not the other way around!).

 +   * If you want to place an object at a certain position you may use this page for calculations: [[http://en.mygeoposition.com/]]
 +    Search for Little River, California. We get the first approach to our target position.

 +It displays Google map worldwide, so we can move and zoom into our desired position. Switch to Satellite, then click with the mouse to the favored point. This opens a window with the appropriate coordinates.
