| - | This element is especially designed to allow you to define exactly the same airspace in a map. | + | |
| - | draw an arc with center position <point1> and given radius from <point2> to <point3> in a clockwise direction using the amount of segments given. | + | <del>Method 1 : Using center and start/end |
| - | Three <point> elements are required. | + | Requires one <point> element to be the center of the arc. |
| + | Requires start and end attributes to be set to the desired start and end angles of the arc (in degrees, range 0-360)</del> | ||

| - | ===== example ===== | + | Method 2 : Using 3 points |
| + | |||
| + | Requires three <point> elements. | ||
| + | Builds an arc that centers on the first point and passes by the specified two other points. | ||
| + | |||
| + | AIS publications such as AIP's use three-point arcs to define lateral airspace borders. | ||
| + | This method is especially designed to allow you to define exactly the same airspace in a map. | ||
