hitTest returns features for all visible layers, so it is necessary to filter the results for the layer of interest. capabilitiesObjectreadonly 1. The FeatureLayer achieves this by working directly with the Feature Service, which can return data based on the needs of the layer. This sample demonstrates applying filters to a local feature layer.

An array of objectIds of the features to be filtered. A where clause for the feature filter. The source data for a feature layer can be hosted onArcGIS OnlineorArcGIS Enterpriseor it can be created from an array on the client. You will learn: how to build an app to use client-side and server-side SQL and spatial expressions to limit data displayed. When a feature layer is filtered, only the features that match the criteria will be displayed. This sample shows how to create a Feature Layer from client side graphics. One of the key differences between server-side and client-side filtering is that client-side filtering is only possible after the feature layer is added to a map and the attributes are present.

Create a feature layer for the trails and add it to the map. L.esri.Layers.FeatureLayer. If a Filter is set on a Feature Layer, ArcIMS Java Connector normally sends a GET_FEATURES request. The tutorial will build off the WPF application you createdin the previous tutorial. The disjoint spatial relationship returns features in the layer view that do not intersect the filter geometry in anyway. In the MapViewModel.cs, the class initializer method will simply call a single method, InitializeMap(). It is opposite of contains. Accordingly, other out-of-the-box widgets, if applicable, will respond to the change it makes in the layer. See the properties for a list of all the properties that may be passed into the constructor. Active 4 years, 7 months ago. Another form of filtering is to use the hitTest method on the view to find features at a given screen location. Start with the same code you used in the previous tutorial. Using the in the last and not in the last operators, you can also apply a dynamic date filter to a hosted feature layer to show events that occurred relative to the current day—for example, all features that were edited in the last five days—without having to manually update the filter each day. They do not return geometry or attribute information associated with the filtered features. In this section, you will learn how to select and highlight a sub-set of a feature service’s data. You can rate examples to help us improve the quality of examples. Für Daten in der Enterprise Geodatabase kennen wir die Benutzerverwaltung, um die Daten sicher vor ungewollten Zugriffen zu schützen und um festzulegen, welche Personengruppe nur lesenden und welche auch schreibenden Zugriff auf die Daten erhalten. Only the features that meet the requirements specified in the filter will be displayed. Include Inherited Members Include Protected Members. L.esri.FeatureLayer also fires all L.esri.FeatureLayerService events.. The InitializeMap()method will populate the map and set the initial viewpoint. | Privacy | Terms of use | FAQ, "esri/views/layers/support/FeatureFilter", // display rain gauges where their water percent is over 30%, // and if the gauges are completely contained by the 10-mile, Any properties can be set, retrieved or listened to. The boundaries of the geometries intersect, but not their interiors. Product Availability. The geometry to apply to the spatial filter. Properties:Example:// Once the layer loads, check if the// supportsAdd operations is enabled on the layerfeatureLayer.when(function(){ if (featureLayer.capabilities.operations.supportsAdd) { // if new features can be created in the layer // set … For spatial filters, this parameter defines the spatial relationship to filter features in the layer view against the filter geometry. For example, you may want to know if a polygon representing a county completely contains points representing settlements. Wie ist es aber mit von ArcGIS verwalteten Daten, den Hosted Feature Layer? Syntax. ESRI.ArcGIS.ADF.IMS: Send comments on this topic. The spatial relationship is determined by whether the boundaries or interiors of a geometry intersect. Update the filter with the code below to show the excluded features with 50% opacity. Suppose I want to limit the extent of a feature layer to a geometry (say a circle). More information about Feature Layers can be found in the L.esri.FeatureLayer documentation. In der Sicht lassen sich andere Eigenschaften (Freigabe, Bearbeitung, Symbolisierung, Filter, etc.) Run the code and select the different query options to filter the layer features. Only the features that meet the filter's expression criteria will be visible in the map. Creates a deep clone of FeatureFilter object. query the group of tracts from the layer using esri query task and store the geometry in an array. Esri Developer Summit 2020 - Technical Workshop. The spatial relationships discover how features are spatially related to each other. Viewed 970 times 3. The filter will use that buffer to display features in the layer or layer view that adhere to the to the indicated spatial relationship. Specifies a search distance from a given geometry in a spatial filter. Mesh geometry types are currently not supported. ArcGIS.Desktop.Mapping Namespace: FeatureLayer Class: For a list of all members of this type, see FeatureLayer members. 4,873 6 6 gold badges 34 34 silver badges 40 40 bronze badges.

Converts an instance of this class to its ArcGIS portal JSON representation. In the example below: From the initial zoom, if 'fatal' is chosen as a severity level, I expect five features in England and two Scotland. In other words, the geometries share some interior area, but not all interior area. The Date field to be used for timeExtent should be added to outFields list when the layer is initialized. The contains spatial relationship returns features in the layer view that are completely contained by the filter geometry. The overlaps spatial relationship returns features in the layer view that overlap the filter geometry. In the require statement, add a reference to the FeatureLayer module. C# (CSharp) ESRI.ArcGIS.Carto FeatureLayer - 3 examples found. These are the top rated real world C# (CSharp) examples of ESRI.ArcGIS.Carto.FeatureLayer extracted from open source projects. Suppose you want to … To learn how to access and display data using a query, visit the Query a feature layer tutorial. In other words, the filter geometry is completely within the features in the layer view. Client-side Filters: To access a subset of data on the client, you have to add the feature layer to a map first, and then set the filter property on a FeatureLayerView object. Answer. The article in the Related Information section below describes how to retrieve the coordinate list for a feature using the com.esri.aims.mtier.model.map.layer.query.Geometry class.

A range of time with start and end date. The ArcGIS API for JavaScript uses AMD modules. The name of the class. Feature Layers are provided by Feature Services which can contain multupile layers. The envelope-intersects spatial relationship returns features in the layer view that intersect the envelope (or extent) of the filter geometry. Applications can perform server-side or client-side SQL and spatial filters to access and display data from feature layers. | Privacy | Terms of use | FAQ, "https://services3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Trails_Styled/FeatureServer/0", // Return all fields so it can be queried client-side, "The trail elevation gain is {ELEV_GAIN} ft.", "width: 275px; font-family: Avenir Next W00; font-size: 1em;". Client-side filters execute very quickly. Indicates the layer's supported capabilities. As long as a filter is set on a single feature layer, the filter displays the expected results.
