Sometimes, which coverage attributes to use is uncertain, especially when importing a layer from another source (GIS, CAD). The general coverage allows creating or editing points/nodes, arcs, and polygons without defining attributes, or worrying about special rules associated the different coverages and attributes. For examples WMS requires that stream and time computation arcs be defined from downstream to upstream.
When importing data from another source, there is no guarantee of the ordering, and if importing them to a Drainage Coverage type, it may cause problems. Therefore, import them to a general coverage, make appropriate edits (streams can be reordered by selecting the downstream most point and choosing the Reorder Streams command from the Feature Objects menu), and then convert the coverage to a drainage type.
