Computing Aspect Ratio and Shape Factor Information
Aspect ratio and shape factor information can be easily determined from other calculated
values. These derived quantities are not stored but calculated, whenever necessary, for the
purposes of display or data dumping. The calculations used are shown below.
Aspect ratio is the ratio of the leaf length to its maximum width. It can be calculated from the
equation:
Shape factor is the ratio of the leaf area to the leaf perimeter, corrected so that the shape factor
of a circle is equal to one. It can be calculated from the equation:
