3.1.2 Length Rotation

(L Rot.) is the rotation angle of the drawn line. This angle is relative to the

horizontal line of the across-track vector. As indicated in Figure 8, angles

above the imaginary horizontal line are positive (>0); angles below the

imaginary horizontal line are negative (<0). The angle’s value is not

computed in the bitmap space but is based on real ground distances (that is,

the angle value takes into account that the scale is different in the along-

track and across-track direction).
