If no weight raster is provided, a weight of 1 is applied to each pixel, and the value of pixels in the output raster is the number of pixels that flow into each pixel.

Output pixels with a high flow accumulation are areas of concentrated flow and can be used to identify stream channels. Output pixels with a flow accumulation of zero are local topographic highs and can be used to identify ridges.<\/div>", "tags": [ "System Raster Function", "Raster Function Template", "Hydrology", "Flow Accumulation" ], "snippet": "Creates a raster of accumulated flow into each cell.
