# VectorFieldRenderer

## Resumen

Visualize flow direction and magnitude information in your raster with vector symbols.

## Debate

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.

## Sintaxis

`VectorFieldRenderer (raster, {is_uv_components}, {reference_system}, {mass_flow_angle_representation}, {calculation_method}, {symbology_name})`
 Parámetro Explicación Tipo de datos raster The input raster. Raster is_uv_components Specifies whether the input components represent U-V, or magnitude and direction.True—The input data represents U-V components.False—The input data represents magnitude and direction components. This is the default. (El valor predeterminado es None) Boolean reference_system Specifies how the direction component is measured.1—Direction is measured in arithmetic coordinates. 0° points due east, and 90° points due north.2—Direction is measured in geographic coordinates. 0° points due north, and 90° points due east. (El valor predeterminado es 2) Integer mass_flow_angle_representation Specifies the angle of mass flow.0—From—The mass is flowing along the angle and moving toward the origin of the reference system. This is sometimes referred to as the meteorological convention.1—To—The mass is flowing along the angle and moving away from the origin of the reference system. This is sometimes referred to as the oceanographic convention. (El valor predeterminado es From) Integer calculation_method[calculation_method,...] Specify the thinning method to be used to calculate the magnitude and direction value of a tile.Vector Average—The following calculation occurs for each pixel: convert direction and magnitude to U and V components, calculate the averages of U and V for all pixels in a tile, and then convert the average U and average V back to direction and magnitude.Nearest neighbor—Uses the value from the pixels closest to the center of the tile.Bilinear—Bilinear resampling will be performed on the tile.Cubic—Cubic convolution resampling will be performed on the tile.Minimum—The minimum pixel value of the tile.Maximum—The maximum pixel value of the tile.(El valor predeterminado es Vector Average) String symbology_name[symbology_name,...] Name of the symbol depicting direction and magnitude.Single Arrow—A single arrow depicting direction and magnitude.Wind Barb—Wind barbs indicating wind direction and magnitude.Ocean Current—Ocean current symbol indicating current and magnitude. (El valor predeterminado es Single Arrow) String
Valor de retorno
 Tipo de datos Explicación Raster The output raster displayed according to your rendering parameters.
