I want to add wind direction and strength to a cost distance surface. The Help file show example of file with two columns - Direction in Degrees, and second value strength (which I assume would cover the full 360 degree azimuth).
0 1.40 10 2.43 20 2.30 30 3.44 40 1.25 50 1.02 60 0.90 70 0.86 80 0.25 90 0.78 100 1.49 110 2.35 120 3.32 130 2.39 140 3.18 150 2.13 160 1.89 170 1.20 180 2.034
How do I create a raster surface which incorporates these two factors to create a friction surface?
Do you have to create a direction surface, Wind Strength surface and add them together?
Is there a simple process to add all the friction costs together in one step?
Thanks in advance for any and all suggestions.
