The boundaries of the geometries intersect, but not their interiors. The possible values for this parameter are described below and the images highlight the geometries returned for the specified spatial relationship for given geometries. I need to create a simple webpage where I can see the result of filters in arc online into it instead of creating the filter each day. Explore the capabilities of the feature layer that directly connects to your data. Feature layers are most appropriate for visualizing data on top of your basemaps. The Date field to be used for timeExtent should be added to outFields list when the layer is initialized. Filters allow you to retrieve a subset of records that match an attribute or spatial query. Types of spatial relationships that can be validated. Indicates the layer's supported capabilities. But when the filter is set on multiple feature layers, I experience multiple issues. Copyright © 2021 Esri. The overlaps spatial relationship returns features in the layer view that overlap the filter geometry. It is opposite of contains. The tutorial will build off the WPF application you createdin the previous tutorial. Add the following code to highlight features as the cursor moves. Esri Developer Summit 2020 - Technical Workshop. The Filter widget allows you to limit the visibility of features in a layer. A collection of features and their visual representation. The FeatureLayer achieves this by working directly with the Feature Service, which can return data based on the needs of the layer. The source data for a feature layer can be hosted onArcGIS OnlineorArcGIS Enterpriseor it can be created from an array on the client. Overview. Active 4 years, 7 months ago. Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. 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. In the require statement, add a reference to the FeatureLayer module. Run the code and test out the select element and the different query options.NOTE: No filter has been applied so all of the data will be displayed. When a feature layer is filtered, only the features that match the criteria will be displayed. This property requires a filter and an excludedEffect, which will be used to style and draw the excluded features. You can apply a client-side filter by filtering the FeatureLayerView after the features have been loaded and the FeatureLayerView is ready. For i As Integer = 0 To myFeatureLayer.SelectionCount - 1 myFeatureLayer.SelectedGraphics.ToList()(i).UnSelect() Next i ' Select the Graphic from the e object … A range of time with start and end date. The filter will use that buffer to display features in the layer or layer view that adhere to the to the indicated spatial relationship. Only lines and polygons have boundaries. . In CodePen, click Fork and save the pen as ArcGIS JavaScript Tutorials: Filter a feature layer. 4,873 6 6 gold badges 34 34 silver badges 40 40 bronze badges. 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. Opposite of intersects. Be sure to have the correct sequence of single and double quotes when writing the where clause in JavaScript. | 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;". In essence, setting this property creates a buffer at the specified size around the input geometry. See the properties for a list of all the properties that may be passed into the constructor. Only the features that meet the expression criteria will be visible in the map. Supported Platforms. In contrast, FeatureLayer has a wealth of dynamic capabilities, including editing, querying/filtering, and support for on-the-fly rendering and projecting. Add an event handler to the selectFilter element to get the selected sql expression and call the setFeatureLayerFilter function. 1. answered May 12 '17 at 13:09. See the, // display features that are completely within state, // Get a query object from the filter's current configuration, // set a geometry for querying features by the view's extent, // query the layer with the modified params object, // prints the array of result graphics to the console, A new instance of a FeatureFilter object equal to the object used to call. , only the features in the selected SQL expression when the filter.!
