Voxel Layer

A voxel layer represents multidimensional spatial and temporal information in a 3D volumetric visualization. You can analyze the volume by slicing, creating sections or isosurfaces. For example, you can visualize atmospheric or oceanic data, a geological underground model, or space-time cubes as voxel layers.

Properties

Property	Details
customParameters	A sequence of custom parameters appended to the URL of all requests related to a layer.
disablePopup	disablePopups allows a client to ignore popups defined by the service item.
id	A unique identifying string for the layer.
itemId	Optional string containing the item ID of the service if it's registered on ArcGIS Online or your organization's portal.
layerDefinition	Additional properties that define drawing of a voxel layer.
layerType	String indicating the layer type. Valid value of this property Voxel
listMode	To show or hide the layer in the layer list. Valid values: hide show
popupInfo	A popupInfo object defining the content of pop-up windows when you click a point.
showLegend	Boolean value indicating whether to display the layer in the legend. Default value is true.
timeAnimation	Indicates whether to enable time animation if the layer supports it.
title	A user-friendly string title for the layer that can be used in a table of contents. If this is not included, a title is derived from the service.
url	The URL to the layer.
visibility	Boolean property determining whether the layer is initially visible
visibilityTimeExtent	Represents time extent that will control when a layer should be visible based on webscene's current time. Visibility time extent only affects the layer visibility and will not filter the data.
