Watershed Analysis

Summary

Fills no-data cells in Target Raster by propagating data values in the inverse (ie. upward) flow direction given by D8-encoded Flow Direction.

In typical usage, the Target Raster is the Strahler order for stream cells and no data elsewhere, and the result is a raster map of watersheds, identified by their Strahler order.
