Is there a way to set a geometry filter on a esri.layers.FeatureLayer? hitTest returns features for all visible layers, so it is necessary to filter the results for the layer of interest. The declared class name is formatted as esri.folder.className. Define a list of SQL expressions and use the list to generate a Select HTML element with an option for each expression. For example, you may want to know if a polygon representing a county completely contains points representing settlements. But when the filter is set on multiple feature layers, I experience multiple issues. In other words, the geometries share some interior area, but not all interior area. For apps where users can interactively change fields used for attribute filter, we suggest you include all possible fields in the outFields of the layer. A feature layer is a grouping of similar geographic features, for example, buildings, parcels, cities, roads, and earthquake epicenters. In other words, the filter geometry is completely within the features in the layer view. use esri ... javascript gis esri esri-maps. Interior — Points are entirely interior and have no boundary. Run the code and select the different query options to filter the layer features.

Update the filter with the code below to show the excluded features with 50% opacity. The envelope-intersects spatial relationship returns features in the layer view that intersect the envelope (or extent) of the filter geometry. Specifies a search distance from a given geometry in a spatial filter. The possible values for this parameter are described below and the images highlight the geometries returned for the specified spatial relationship for given geometries. When a feature layer is filtered, only the features that match the criteria will be displayed. The unit for calculating the buffer distance when distance is specified in a spatial filter. The boundaries of the geometries intersect, but not their interiors. Any legal SQL92 where clause operating on the fields in the layer is allowed. Describes the layer's supported capabilities. Client-side filters execute very quickly. 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. L.esri.FeatureLayer also fires all L.esri.FeatureLayerService events.. How can a complete geometry of a selected feature be returned in a FeatureLayer using Java Connector? Add the element to the top-right of the view. Another form of filtering is to use the hitTest method on the view to find features at a given screen location. Suppose you want to … query the group of tracts from the layer using esri query task and store the geometry in an array.
