A single value or rating for each reap unit is gated by aggregating <br />the interpretive ratings of individual map unit components. This aggregation process <br />is defined for each interpretation. <br />Vegetative Productivity <br />Vegetative productivity includes esonews of potential production for a <br />variety of land rises. induding cropland, flora, Wand.
