vectorField

Method Overview

Method Details

createRenderer(params){Promise<VectorFieldRendererResult>}

Generates a VectorFieldRenderer to display raster data with vector symbols. This renderer is often used for visualizing flow direction and magnitude information in meteorology and oceanography raster data.

Parameters

Specification

params Object Input parameters for generating a vector field visualization. See the table below for details of each parameter. Specification layer ImageryLayer|ImageryTileLayer The input layer for which the renderer is generated. renderingRule RasterFunction optional Specifies the rule for how the requested image should be rendered. When renderingRule is applied, the server returns updated service information that reflects custom processing as defined by the rendering rule. If not provided, the output renderer is created using the layer's renderingRule. flowRepresentation String optional Defines the flow direction of the data. This can be modified to display meteorological (the direction it is flowing from) or oceanographic data (the direction it is flowing to). See VectorFieldRenderer.flowRepresentation for more information. Possible Values:"flow-from"|"flow-to" rotationType String optional Defines the origin and direction of rotation depending on how the angle of rotation was measured. This property only applies to rotations around the heading axis. See VectorFieldRenderer.rotationType for more information. Possible Values:"geographic"|"arithmetic" style String optional The predefined symbol styles used to represent the vector flow. See VectorFieldRenderer.style for more information. Possible Values:"beaufort-ft"|"beaufort-km"|"beaufort-kn"|"beaufort-m"|"beaufort-mi"|"classified-arrow"|"ocean-current-kn"|"ocean-current-m"|"simple-scalar"|"single-arrow"|"wind-barb" signal AbortSignal optional Allows for cancelable requests. If canceled, the promise will be rejected with an error named AbortError. See also AbortController.

Returns

Type	Description
Promise<VectorFieldRendererResult>	Resolves to an object containing a VectorFieldRenderer that can be set on the input layer.

Type Definitions
