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.

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

ParameterDescription

Raster1

The first input raster.

This will either be the U value or the magnitude.

Raster2

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.
