The value of this property matches the name of one of the fields of the layer. The name of an oid field containing a unique value or identifier for each feature in the layer. If the geometry consists of multiple points (e.g. To query for ObjectIDs of features/graphics available to or visible in the View on the client rather than making a server-side query, you must use the FeatureLayerView.queryObjectIds() method. // used for other layers that may be loaded from portalItem ids. Only the features that satisfy the definition expression are displayed in the View. At the bottom of each page look for "Supported Options" and try using the Query functionality to find and return records in each dataset. The feature service's metadata JSON exposed by the ArcGIS REST API. // in the source array if they are not specified. Fields specified in outFields will be requested alongside with required fields for rendering, labeling and setting the elevation info for the layer. Features may be visualized with the same symbol using SimpleRenderer, by type with UniqueValueRenderer, with class breaks using ClassBreaksRenderer, or with continuous color, size, or opacity schemes using visual variables in any of the renderers. The subsequent calls return the same promise. Everything else is made transparent. If the add method is used without an index value, the layer is appended to the end of the collection, so it draws last. The renderer assigned to the layer. The file needs to include at least one pair of coordinate fields as these fields are used to locate the features on the map. Effect provides various filter functions that can be performed on the layer to achieve different visual effects similar to how image filters work. This operation is only supported in ArcGIS Online hosted feature services. This object can be either pre-uploaded data or base 64 encoded data. Can be thought of as the opposite of the. The top layer is displayed over the background layer. The timeInfo parameters cannot be changed after the layer is loaded. For example, the following snippet shows how to add a new FeatureLayer instance to a map using the portalItem property. Indicates if the layer supports a SQL-92 expression or where clause. If historicMoment is not specified, the query will apply to the current features. The service definition expression limits the features available for display and query. For example, you can use multiply blend mode on a topographic map displayed over hillshade when you want to have your elevation show through the topographic layer. Overview. javascript arcgis esri arcgis-js-api. The minimum scale (most zoomed out) at which the layer is visible in the view. Applications can access and display feature layers that are hosted on ArcGIS Online or ArcGIS Enterprise.A hosted feature layer contains features (records) with a geometry and a set of attributes. Map layers in the layers collection are drawn in the order they are added (first layer to the last layer in collection). 1. 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. An array of successfully deleted features. Black in the top layer will stay unchanged. Indicates whether there is an event listener on the instance that matches the provided event name. // the first layer in the service is returned, // Set hostname when using an on-premise portal (default is ArcGIS Online). This is valid only for hosted feature services. The version of the geodatabase of the feature service data. Updates an existing attachment for a feature. The following blend modes use primary color components, which are hue, saturation and luminosity to blend top and background layers. Some of these modes are designed to simulate the effect of shining a light through the top layer, effectively projecting upon the layers beneath it. Run your code to view the map with the trailheads layer. The object's resources have loaded without errors. Can be thought of as the opposite of, Colors in top and background layers are multiplied by their alphas (layer, Colors in top and background layers are added together. It will return an error if the layer's capabilities.data.supportsAttachment property is false. For example, index 0 will add as the first layer, and will draw first. The following screenshots show feature and imagery layers on the left side on their own in the order they are drawn in the 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. This method takes two input parameters: a callback function and an errback function. The query methods in the FeatureLayer class query features directly from the service. A convenient property that can be used to make case-insensitive lookups for a field by name. For line and polygon geometries the result of the expression is the same for all vertices of a feature. If the map is zoomed out beyond this scale, the layer will not be visible. The layer is visible in the table of contents. If the add method is used without an index value, the layer is appended to the end of the collection, so it draws last. Values of non nullable fields must be provided when updating features. The name of the field holding the type ID or subtypes for the features. This property is read-only when the layer is created from a url. Fires after the layer's LayerView is destroyed and no longer renders in a view. // Non-spatial table in San Francisco incidents service. If the source is an empty array at the time of layer initialization, then geometryType must be set. Fetches custom attribution data for the layer when it becomes available. In darken blend modes, pure white in the top layer will become transparent allowing the background layer to show through. To query for the count of features/graphics available to or visible in the View on the client rather than making a server-side query, you must use the FeatureLayerView.queryFeatureCount() method. It's possible to provide a signal to stop being interested into a Loadable instance load status. The data of the top layer block the data of background layer where they overlap. Colors in the top layer become transparent if they are darker than the overlapping colors in the background layer allowing the background layer to show through completely. // Define parameters for querying attachments. The Overflow Blog Podcast 286: If you could fix any software, what would you change? Example: The service has a horizontal spatial reference using feet units and the query is made with outSpatialReference based on meter units, then queryFeatures() automatically converts the values from feet to meter units. If add is used with an index value, it will place the layer the appropriate location in the collection. The plus, lighten and screen modes can be used to brighten layers that have faded or dark colors on a dark background. If the gdbVersion parameter is not specified, edits are made to the published map’s version. Array of relationships set up for the layer. Map layers in the layers collection are drawn in the order they are added (first layer to the last layer in collection). Cancels a load() operation if it is already in progress. // The layer's visibility is not restricted to a maximum scale. Indicates if the query operation supports using standardized queries. Both spatial and non-spatial feature collections require an objectId field, this must be indicated along with an array of field objects, providing the schema of each field. They provide unlimited flexibility so that you can create very elaborate and intricate symbols. See ArcGIS Pro subtypes document. If you're using the standard ArcGIS for Power BI visualization that comes with Power BI, you'll only see publicly shared feature service layers when you add a reference layer. See the intro to layer blending sample. // Offset a CSV Layer containing hurricanes from 2015 so that they appear in 2019 (+4 years). Sample: Add multiple label classes to a layer, Sample: Flat vs. volumetric 3D symbol layers. The blended result shows areas of cultivated crops only (where both imagery and feature layers overlap). Check out add or remove graphics from a FeatureLayer sample to see this in action. See elevationInfo for details regarding placement and rendering of features with z-values in 3D SceneViews. Each item includes information about the type, such as the type ID, name, and definition expression. Signal object that can be used to abort the asynchronous task.
