Figure 3.9: New Theme Creation in ArcView
A polyline is used to represent the longest flow path. Once the polyline is drawn (or polygon for area), ArcWorkstation is used to convert the new themes to coverages. After the polylines and polygons are converted to coverages, they are processed using the ArcWorkstation commands build and clean. Following this process the coverages are opened once again in ArcView GIS 3.2 and converted back to shapefiles.
