Cartesian Data
2-grid vector maps created with Cartesian data require that one grid contains X component data and a Y component data grid. The data from the two grids are combined to produce vector direction and magnitude. The components can be in either negative or positive space. The direction and magnitude of the resulting vectors are determined from the two grids as shown in the following example.
Example
The lower right corner's X component is 3.5 and the Y component is 3.5. To simplify the math, the origin of both are zero. The direction of the resulting vector is found by adding the two vectors together:
The magnitude of the vector is:
