I have two raster layers representing the U and V components of a vector wind. I could generate the magnitude raster by applying Square root in Map Algebra in ArcGIS.

I also generated a raster layer of wind direction by two formulas:

x = ATan2(-v, -u) / (2*3.14159265) + 1

(x - Int(x)) * 360

How can I plot Vector Arrows from U and V Component with ArcGIS for Desktop?

  • Can you provide an image of what the end result would look like? – artwork21 Jan 22 '15 at 23:25
  • Yes, I plotted two raster layers (direction and magnitude) – Habib Jan 22 '15 at 23:30
  • In your question – artwork21 Jan 22 '15 at 23:31
  • Does blogs.esri.com/esri/arcgis/2013/07/17/… help at all? – BradHards Jan 22 '15 at 23:37
  • I provided raster layers of direction and magnitude but i want to generate arrow vector wind. I don't know how can do it – Habib Jan 22 '15 at 23:39

If you have ArcMap 10.3 or higher you can symbolize magnitude and direction with the vector field symbology method. Information about how to set up this display method is found in the help file here.
