Stream Order for drainage to streams in the Ipswich or Parker River Network - ASCII Raster 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. 3rd order pixels are equivalent to 1st order streams, 4th order pixels are second order streams, etc). Idenitify the distribution of inputs from land to streams of different sizes.
