The following example illustrates how to define an attribute: Vector_Attributes Attributes Attribute code=2 symbol=AO1 NameAngle of OrientationName DescriptionAngle of Orientation with greater than 1 degree resolution. The angular distance measured from true north 0 deg clockwise to the major Y axis of the feature. If the feature is square, the axis 0 through 89.999 deg shall be recorded. If the feature is circular, 360.000 deg shall be recorded.
