The GeoJSON layer type references a GeoJSON file from a publicly-accessible web server. It then dynamically loads into the scene at run time. The GeoJSON layer will maintain a reference to the GeoJSON resource.

Properties
| Property | Details |
|---|---|
| customParameters | A sequence of custom parameters appended to the URL of all requests related to a layer. |
| disablePopup | Indicates whether to allow 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 if it's registered on ArcGIS Online or your organization's portal. |
| layerDefinition | Additional properties that define drawing information and other configurations for the layer. See layerDefinition properties table. |
| layerType | String indicating the layer type. Valid value of this property GeoJSON |
| listMode | To show or hide layers in the layer list Valid values:
|
| maxScale | A number representing the maximum scale at which the layer will be visible. The number is the scale's denominator. |
| minScale | A number representing the minimum scale at which the layer will be visible. The number is the scale's denominator. |
| opacity | The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency. |
| popupInfo | A popupInfo object defining the content of popup windows when you click or query a feature. |
| refreshInterval | Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled. |
| screenSizePerspective | Apply perspective scaling to screen-size symbols. |
| showLabels | Labels will display if this property is set to true and the layer also has a labelingInfo property associated with it. This property can get stored in the web scene config. |
| 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. |
| url | The URL to the layer. |
| visibility | Boolean property determining whether the layer is initially visible in the web scene. |
| 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. |
layerDefinition properties
| Property | Details |
|---|---|
| definitionExpression | SQL-based definition expression string that narrows the data to be displayed in the layer. |
| drawingInfo.labelingInfo[] | An array of labelingInfo objects. |
| drawingInfo.renderer | The renderer object contains the drawing information for the operationalLayer. |
| elevationInfo | Elevation info defines how features are aligned to ground or other layers. |
| featureReduction | An object that specifies how features are reduced or aggregated, with the goal of decluttering the view or presenting the user with an aggregate visualization. |
| fields[] | An array of field objects containing information about the attribute fields for the feature collection or layer. |
| objectIdField | Indicates the name of the object ID field in the dataset. |
