Tool Downslope Area (interactive)

This interactive tool allows you to specify source cells (with a left mouse click), for which the downslope area shall be identified. For the 'Deterministic Infinity' and 'Multiple Flow Direction' algorithms, which are able to simulate flow divergence, the result will give the percentage of the source cell's flow that drains through each cell.
