BRIEF DESCRIPTION OF DATA FILE:

This datalayer is a gridded data set that identifies for each pixel the stream order that drainage from the pixel initially enters into the river network. The resolution is 120 m x 120 m. Based on the flow direction in: WAT-RGIS-120m-FlowDirection.asc. First order streams at the 120m resolution are equivalent to third order when calculated at the pixel level from the drainage direction grid (i.e. 3^rd order pixels are equivalent to 1^st order streams, 4^th order pixels are second order streams, etc).
