| Video Discription | As in Lab Exercise 2, here we will use the Flow Direction tool to calculate flow direction using the D8 method across the landscape around Picture Canyon. This time the flow direction will allow continuous flow across the entire landscape because we have filled in the sinks in Lab Exercise 3. We will also see why the Flow Direction tool produces the eight specific flow direction values it does (1, 2, 4, 8, 16, 32, 64 and 128).
