Dear all I have a current velocity filed u and v, and would like to calculate the velocity and Angel in a way that I can present it using geographical North =O. In the ArcMap I get the correct velocity filed using the following ecuation in rotation experession: (180/pi)*atan2(v,u)+90, using aritmetic presentation. However I would like to have the data, because I need them for the traking analysis which requires angle and length (velocity) raster as input. I didnt find a way to save the data rotated according to the formulae above. Smebody know how to do that.
