arcgis javascript add feature layer

isFulfilled() may be used to verify if creating an instance of the class is fulfilled (either resolved or rejected). A signal to abort the creation of the layerview. Emphasizes the darkest parts of overlapping layers. Für Feature-Layer können Daten aus jeder Quelle verwendet werden, die Punkt-, Polylinien-, Polygon-, Multipoint- oder Multipatch-Vektor-Feature-Daten liefert. A temporary offset of the time data based on a certain TimeInterval. All features must be of the same type. A big thank you, Tim Post. Specifies the attachment parameters for query. Indicates if the query response includes the query geometry. TimeInfo provides information such as date fields that store start and end time for each feature and the fullTimeExtent for the layer. Returns a FeatureType describing the feature's type. If supportsRollbackOnFailure is false for a layer, then rollbackOnFailureEnabled will always be true, regardless of how the parameter is set. If true, queryAttachments() can return attachments for array of objectIds. When creating a FeatureLayer from client-side features, this property is inferred from the geometries of the features provided in the source property. This mode is also known as, Inverts colors of the background layer and multiplies with colors of the top layer. Go to each hosted feature service URL endpoint to learn more about the meta data, data and the functions that are supported. For FeatureLayer the type is always "feature". Indicates how the layer should display in the LayerList widget. AttachmentEdit represents an attachment that can be added, updated or deleted via applyEdits. Browse other questions tagged arcgis-javascript-api feature-layer or ask your own question. An array of successfully updated features. Depending on the renderer type, features may be visualized with the same symbol, or with varying symbols based on the values of provided attribute fields or functions. Indicates whether creating an instance of the class has been resolved. The file needs to include at least one pair of coordinate fields as these fields are used to locate the features on the map. By default, this is worldwide. Run your code to view the map with the trailheads layer. The URL of the REST endpoint of the layer, non-spatial table or service. Indicates if the query operation supports a cache hint. Refer to elevationInfo for details regarding placement and rendering of features with z-values in 3D SceneViews. Explore the feature layers in the map below. Represents the status of a load operation. Feature to which the attachment is to be added. When two pixels with the same value are subtracted, the result is black. Blending with black produces no change. The geometry of each feature all must have a matching geometryType. The required fields and outFields are used to populate FeatureLayerView.availableFields. Key in this case is the. Indicates if values of one or more field values in the layer can be updated. CIMSymbols are multi-layer vector symbols for features and graphics used throughout the ArcGIS platform. In ArcGIS, layers are collections of geographic data. The name of an oid field containing a unique value or identifier for each feature in the layer. For example, the following snippet returns all features from the service, not just the features drawn in the FeatureLayerView. This is valid only for hosted feature services. This map shows carbon storage of trees in Warren Wilson College. If it is fulfilled, true will be returned. The feature layer contains 2007 county crops data. When true, the globalIds must be submitted with the new features. See DynamicMapLayer for creating dynamic layers from map service layers for on the fly rendering, labeling, and filtering (definition expressions). Resolves to an object containing custom attribution data for the layer. The spatial reference of the layer. An array of attachments to be updated. Inverts the background colors wherever the top and background layers overlap. You can change the. When creating the layer from a url, the spatial reference is read from the service. To query features/graphics available to or visible in the View on the client rather than making a server-side query, you must use the FeatureLayerView.queryFeatures() method. Indicates if the layer's query operation supports querying features or records related to features in the layer. See the object specification table below for the required properties of this object. Indicates if the number of features returned by the query operation can be controlled. In these cases it may be better to turn off screen size perspective. When false, indicates that z-values will never be returned. // an array of graphics with geometry and attributes, // popupTemplate and symbol are not required in each feature, // since those are handled with the popupTemplate and. HTML form that contains a file upload field pointing to the file to be added as an attachment. Definition expressions may be set when a layer is constructed prior to it loading in the view or after it has been added to the map. Your app should look something like this. The renderer assigned to the layer. The function to execute when the promise fails. Diese Feature-Classes sind häufig in einer Geodatabase enthalten. Check out multiple blending and groupLayer blending samples to see composite blend modes in action. You may be familiar with the graphics layer from previous releases. It's an object with key-value pairs where value is a string. Add the Trails (lines) and Parks and Open Spaces (polygons) feature layers to the map. // Define parameters for querying attachments. Very large datasets may require potentially long initial load times, particularly at small scales. An Arcade expression evaluating to a number that determines the z-value of the feature. The query object representing the layer's definition expression and other configurations. Value of 0 indicates no refresh. Fires when an error emits during the creation of a LayerView after a layer has been added to the map. // print out layer's relationship length and each relationship info to console, // all features in the layer will be visualized with, // a 6pt black marker symbol and a thin, white outline, // geometryType and spatialReference of the layer, // will be inferred from the first feature in the array, // autocast as a Collection of new Graphic(), "The layer will display data within the view's timeExtent. Indicates if the query operation supports using standardized queries. // set the outFields for the layer coming from webmap, // While this example uses FeatureLayer, this same pattern can be. Objects in the view proxy is required matches the name of the field holding the type such.
