Link Grid separates the stream grid segments at the
junctions. Each Link Grid segment is assigned a unique integer value starting
with 1. The rest of the grid assumes NoData value similar to that of Stream
Grid.
Figure x.x shows the Link Grid generated
corresponding to the Stream Grid obtained in the previous
section.
In the Input section of the dialog browse the Stream
Grid and Flow Direction Grid generated by the step 4.3 and 4.2 respectively. In
