Remarks

The Heading value units are in degrees (0-360), and the heading behaves like a geographic angle, meaning zero value is up (like the north direction) and the heading is increased in a clockwise direction (for example - heading of 90 degrees points to the right).

The Symbol’s Heading direction is calculated to be relative to the Map’s North direction or to the Screen-up direction, according to the value of the RotationAlignment property.

Heading property is not relevant for Line Symbols.
