Summary
Visualize flow direction and magnitude information in your raster with vector symbols.
Discussion
For more information about how this function works, see the Vector Renderer Field raster function.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntax
VectorFieldRenderer (raster, {is_uv_components}, {reference_system}, {mass_flow_angle_representation}, {calculation_method}, {symbology_name})
Parameter | Explanation | Data Type |
raster | The input raster. | Raster |
is_uv_components | Specifies whether the input components represent U-V, or magnitude and direction.
(The default value is None) | Boolean |
reference_system | Specifies how the direction component is measured.
(The default value is 2) | Integer |
mass_flow_angle_representation | Specifies the angle of mass flow.
(The default value is From) | Integer |
calculation_method [calculation_method,...] | Specify the thinning method to be used to calculate the magnitude and direction value of a tile.
(The default value is Vector Average) | String |
symbology_name [symbology_name,...] | Name of the symbol depicting direction and magnitude.
(The default value is Single Arrow) | String |
Data Type | Explanation |
Raster | The output raster displayed according to your rendering parameters. |
