    1. Maritime navigators and map-makers long ago standardized on the compass rose. But the compass echoes the clock face, which in turn mimics the direction of sweep of the sun across the sky when facing South in the Northern hemisphere, and the consequent sweep across the ground of any shadow as observed in the dominant culture of that hemisphere. Accordingly, navigational angles increase toward the right when facing out from any location, with zero usually at the top. Rotation (yaw) is thus positive "clockwise." This is a convention which is not to be contradicted.
