The process of drawing polygons was used to digitize the entire area of the watershed with respect to its land use types.  These images illustrate this process, and show the 2002 land use map about halfway completed.  Here, the individual polygons are visible throughout the expanse of the watershed.
	Once the entire area of the watershed was digitized, the land use maps were finalized by merging the polygons, which joined areas of the same land use type.
