When two links intersect, their magnitudes are added and assigned to the downslope link. (1991). Once created, the stream network can be further analyzed using the Stream Order, Stream Link, and Stream to Feature tools, for ordering (ranking) the streams, assigning unique IDs to stream links, or creating a feature dataset, respectively. The resulting stream network can be used in Stream Link and Stream to Feature. The input stream raster linear network should be represented as values greater than or equal to one on a background of NoData. The output of Stream Order will be of higher quality if the input stream raster and input flow direction raster are derived from the same surface. On the Extraction of Channel Networks from Digital Elevation Data. Future releases will support a wider variety of client subscriptions.
