Web Feature Service Layer (WFS)

OGC Web Feature Service (WFS) is a dynamic feature service that follows the specifications of OGC.

Properties

Property	Details
disablePopup	Indicates whether to allow a client to ignore popups defined by the service item.
id	A unique identifying string for the layer.
itemId	Unique string value indicating an item registered in ArcGIS Online or your organization's portal.
layerDefinition	An object that defines the attribute schema and drawing information for a layer drawn using client-side graphics. See layerDefinition properties table.
layerType	String indicating the layer type. Valid value of this property `WFS`
listMode	To show or hide layers in the layer list Valid values: `hide` `show`
maxScale	Represents the maximum scale (most zoomed in) at which the layer is visible in the view. If the web scene is zoomed in beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a maximum scale. If set, the maxScale value should always be smaller than the minScale value, and greater than or equal to the service specification.
minScale	Represents the minimum scale (most zoomed out) at which the layer is visible in the view. If the web scene is zoomed out beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a minimum scale. If set, the minScale value should always be larger than the maxScale value, and lesser than or equal to the service specification.
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 map config and in the item/data.
showLegend	Boolean value indicating whether to display legend for this layer.
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. If the layer is not from a web service but rather a feature collection, than the url property is omitted.
visibility	Boolean property determining whether the layer is initially visible in the web map.
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.
wfsInfo	Object that defines and provides information about layers in a WFS service.

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.
drawingInfo.transparency	Number value ranging between 0 (no transparency) to 100 (completely transparent).
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.
geometryType	A string defining the type of geometry. Possible geometry types are: `esriGeometryPoint`, `esriGeometryMultipoint`, `esriGeometryPolyline`, `esriGeometryPolygon`, and `esriGeometryEnvelope`.
spatialReference	An object containing the WKID or WKT identifying the spatial reference of the layer's geometry.
