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
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. See layerDefinition properties table.
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
showLegend	Boolean value indicating whether to display the layer in the legend. Default value is true.
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

layerDefinition properties

Property	Details
sections[]	Array of metadata about sections. A section is a static plane through the voxel layer showing the variable the section was created at.
style	Voxel style describes how the layer will be drawn including rendering and voxel representions that will be visible.
