The URL may either point to a resource on ArcGIS Enterprise or ArcGIS Online. Fires after the layer's LayerView is created and rendered in a view. For example, you can use difference or exclusion blend modes on two imagery layers of forest covers to visualize how forest covers changed from one year to another. The portal item from which the layer is loaded. Black pixels in the background layer are ignored as if they were transparent. This operation is supported in ArcGIS Online hosted feature services created since December 2016 and ArcGIS Enterprise feature services since version 10.7. Each item includes information about the type, such as the type ID, name, and definition expression. Indicates whether the client-side features in the layer have M (measurement) values. A big thank you, Tim Post. If true, queryAttachments() can return attachments for array of objectIds. Setting a definition expression is useful when the dataset is large and you don't want to bring all features to the client for analysis. Indicates how the layer should display in the LayerList widget. Indicates whether creating an instance of the class has been rejected. // esriConfig.portalUrl = "http://myHostName.esri.com/arcgis"; // loads the third item in the given feature service. If unit is not defined, the offset is in meters. For information regarding how to create a LayerView for a particular layer, see View.whenLayerView(). The unique ID assigned to the layer. Requires ArcGIS Server service 10.1 or greater. The version of the geodatabase of the feature service data. Currently, this field only displays the count of attachments per feature. Returns true if the layer is loaded from a non-spatial table in a service. Describes characteristics of the data in the layer. Sample - Point clustering with visual variables. Signal object that can be used to abort the asynchronous task. // Add an attachment to the clicked feature. See ArcGIS Pro subtypes document. If the definition expression is set after the layer has been added to the map, the view will automatically refresh itself to display the features that satisfy the new definition expression. The unit for featureExpressionInfo and offset values. See the table below for a list of possible values. The LayerView rendered in the view representing the layer in layer. // The layer's visibility is not restricted to a minimum scale. If the map is zoomed out beyond this scale, the layer will not be visible. Explore the feature layers in the map below. You should see all three layers. As of version 4.17, using applyEdits to add geometries with z-values to a FeatureLayer with hasZ: false no longer silently drops the z-value and now throws an error. New features can be created and existing features can be updated or deleted. See the darken blending sample. ArcGIS API for JavaScript Home Guide API Reference Sample Code Support. However, if the source property is an empty array at the time of initialization, then geometryType cannot be determined and the layer will be rejected. You will learn: how to build an app that displays feature layers in a 2D map. Call this method to hook an event with a listener. The label definition for this layer, specified as an array of LabelClass. when() may be leveraged once an instance of the class is created. If no parameters are specified, then the extent and count of all features satisfying the layer's configuration/filters are returned. It sets the query parameter's outFields property to ["*"]. Requires ArcGIS Server service 10.1 or greater. Fetches custom attribution data for the layer when it becomes available. The layer can be either a spatial (has geographic features) or non-spatial (table). // Non-spatial table in San Francisco incidents service. The subsequent calls return the same promise. If historicMoment is not specified, the query will apply to the current features. The results will include geometries of features and values for all available fields for client-side queries or all fields in the layer for server side queries. Requires ArcGIS Server service 10.5 or greater. For example, if you published the hosted feature layer from ArcGIS Pro, overwrite the service from ArcGIS Pro. Creates a popup template for the layer, populated with all the fields of the layer. Get the API; What’s new; Licensing; Visualize your data in 2D and 3D. The feature containing the attachment to be updated. Each layer can contain an unlimited number of features. Returns the Domain associated with the given field name. Fires after applyEdits() is completed successfully. This is only applicable if the feature layer supports attachments. Features are placed at an absolute elevation (z-value) above sea level. If false, queryAttachments() method can only return attachments for one feature at a time. The color-burn mode works well with colorful top and background layers since it increases saturation in mid-tones. The blended result shows areas of cultivated crops only (where both imagery and feature layers overlap). When called, removes the listener from the event. If you or other editors add features to the layer that are outside the initial extent of the layer, the spatial index becomes outdated and you may need to rebuild it. // Date.now() returns number of milliseconds elapsed, // or specify globalIds of features to be deleted, // { globalId: "18633204-1801-4d35-a73a-174563608ad9" }, // globalIdUsed has to be true when adding, updating or deleting attachments, // this snippet shows the query parameter object that is returned, // Get a query object for the layer's current configuration, // queryParams.outFields will be set to ["*"] to get values, // set a geometry for filtering features by a region of interest, // Add to the layer's current definitionExpression, // query the layer with the modified params object, // prints the array of result graphics to the console, // Get a range domain associated with the first feature. Specifies the attributes and spatial filter of the query. The content type of the attachment. At 10.3, this option is only available for hosted feature services. The spatial reference of the layer. All layers underneath the top layer are background layers. An array of fields in the layer. The following blend modes create darker results than all layers. Requires an ArcGIS Server service 10.7 or greater. The name of the field holding the type ID or subtypes for the features. You can combine multiple effects in a layer, and use effects on any number of layers in a map. Apply perspective scaling to screen-size point symbols in a SceneView. Source/top layer is drawn where it doesn't overlap the background layer. Specifies how features are placed on the vertical axis (z). Indicates whether the edits should be applied only if all submitted edits succeed. The SQL where clause used to filter features on the client. Creates an effect with the hue of the top layer and the luminosity and saturation of the background layer. I want to add test feature on my ArcGIS map using feature layer. Returns the Domain associated with the given field name. Can be thought of as the opposite of, Creates an effect with the hue and saturation of the top layer and the luminosity of the background layer. I have tried the following: options { ... where: whereClause } new FeatureLayer(url, options); The above does not work. In ArcGIS, layers are collections of geographic data. It doesn't apply to z-values. Map layers in the layers collection are drawn in the order they are added (first layer to the last layer in collection). An array of feature templates defined in the feature layer. Executes a Query against the feature service and returns an array of Object IDs for features that satisfy the input query. When resolved, returns an array of numbers representing the object IDs of the features satisfying the query. If no parameters are specified, the total number of features satisfying the layer's configuration/filters is returned. When creating the layer from a url, the spatial reference is read from the service. Each link will display the layer type, geometry type, extent, drawing information, fields and more. Use this blend mode, when you want an effect with more contrast than multiply or darken. Indicates if the attachment queries support exifInfo. The geodatabase version to apply the edits. For example, if the layer's time extent is set to display features between 1970 and 1975 and the view has a time extent set to 1972-1980, the effective time on the feature layer will be 1972-1975. Programatically add feature to Feature Layer with ArcGIS JavaScript API. See the Labeling guide page for more information and known limitations. The feature service's metadata JSON exposed by the ArcGIS REST API. The value of this property matches the name of one of the fields of the layer.
