A direction in degrees, representing the main horizontal direction of observation.
Remarks
This value tells in which direction the observer is looking. In other words, the horizontal direction of the central line through the sensor lobe. Measured in degrees, clockwise from a zero direction.
Normally, the zero direction is geographic north. But in the special case of a LineOfSightOperator that receives a line feature (with exactly two points) from its observerInput, the zero direction is the course from the first to the second point.
If the PictureWidth is 360 degrees, the PictureDirection will often have no effect.
