Vector Field function

Overview

The Vector Field function is used to composite and convert two rasters into a two-band raster that is either of data type Magnitude-Directionor data type U-V.

Once you specify the parameters, you can use the Vector Field Renderer function to display your raster.

Notes

If the Input Data Type parameter is Magnitude-Direction, you also need to specify the Angular Reference System. parameter.

The U value is sometimes referred to as the zonal velocity, and V value is sometimes referred to as the meridional velocity.

Parameters

Parameter	Description
Input Raster 1	The first input raster. This will either be the U value or the magnitude.
Input Raster 2	The second input raster. This will either be the V value or the direction.
Input Data Type	The type of vector field your inputs represent. Unknown—It is unknown whether the inputs represent U-V or Magnitude-Direction. U-V—Input data represents U and V components. Magnitude-Direction—Input data represents magnitude and direction.
Angular Reference System	Specifies how the direction component was measured. Geographic—0° points due north, and 90° points due east Arithmetic—0° points due east, and 90° points due north
Output Data Type	Specifies the type of vector field your output will represent. Magnitude-Direction—Output data represents magnitude and direction. U-V—Output data represents U and V components.
