Filter for polygon

[BraulioCordova]

I am wanting to do a point filter for a polygon. But when passing the geometry, the points do not filter. Allen Thompson

 mapView.whenLayerView(areaspriorizadas).then(function(featureLayerView) {

       featureLayerView.filter = {

            geometry: distrito,

            patialRelationship: "contains"

        };    

      });

Are the points and the polygon in the same spatial reference?

[BraulioCordova]

If they are in the same coordinate system. But when I pass the parameter of the polygon geometry. I get an error.

let areaspriorizadas = new FeatureLayer({

        url:

        urlservices+"/Areas_Priorizadas/FeatureServer/0",      

        //definitionExpression: "id_dist="+ubigeo,

       // mapView.extent = featureLayer.fullExtent;

        outFields: ["trimestre"]

        //featureReduction: distrito

       // renderer: distrito       

      });

      map.add(areaspriorizadas);    

      //****************************** */

      mapView.whenLayerView(areaspriorizadas).then(function(featureLayerView) {

       featureLayerView.filter = {

            //where: "trimestre='I Trimestre'",         

           geometry: distrito.event.geometry, //Problems in geometry when passing the polygon stops to the exclusion of points.

            patialRelationship: "contains"

        };    

      });

I don't see in your code what distrito.event object is.

[BraulioCordova]

areaspriorizadas is type point
distrito is type polygon
Filtering points within a polygon is required

[RobertScheitlin__GISP]

The issue is that if 

geometry: distrito.event.geometry

was a single polygon with the same spatial reference as areaspriorizadas then there would not be any issue.

So are you sure that distrito.event.geometry is not null and is a single polygon geometry?

[BraulioCordova]

What happens is that I want to filter the points (areaspriorizadas) within a polygon (distrito). At the time of passing the extension to consider. It does not filter the contained points. I have seen that if I put (geometry: view.extent) it filters the extension of the map. But I don't know how to filter the points inside the polygon (distrito)

 var distrito = new FeatureLayer({

        url: urlservices+"/Demarcacion_Territorial/MapServer/2",

        title: 'Distrito',

        //*** ADD ***//

        definitionExpression: "id_dist="+ubigeo,

        //*** ADD ***//

        popupTemplate: {  // Enable a popup

          title: "Distrito", // Show attribute value

         "content": "<b>Departamento:</b> {departamento}<br><b>Provincia:</b> {provincia}<br><b>Distrito:</b> {distrito}<br>"

          }

        });

        map.add(distrito);

 // Visualizacion de areas priorizadas

       let areaspriorizadas = new FeatureLayer({

        url:

        urlservices+"/Areas_Priorizadas/FeatureServer/0",  

        //definitionExpression: "id_dist="+ubigeo,

       // mapView.extent = featureLayer.fullExtent;

        outFields: ["trimestre"]

        //featureReduction: distrito

       // renderer: distrito       

      });

      map.add(areaspriorizadas);    

      distrito.queryExtent().then(function(response){mapView.goTo(response.extent);})

      //****************************** */

      mapView.whenLayerView(areaspriorizadas).then(function(featureLayerView) {

       featureLayerView.filter = {

            //where: "trimestre='I Trimestre'",

            geometry: mapView.geometry.Extent(distrito),

            patialRelationship: "contains"

        };    

      });

As I mentioned before you can only filter the view on a Single geometry. So you would have to get a single feature from the distro featurelayer and grab the one features geometry to use in the filter.

      mapView.whenLayerView(areaspriorizadas).then(function(featureLayerView) {
       var polyFeat, query;
       query = distrito.createQuery();
       query.outSpatialReference = view.spatialReference;
       query.returnGeometry = true;
       distrito.queryFeatures(query).then(function(results){
         polyFeat = results.features[0].geometry;
       });
       featureLayerView.filter = {
          geometry: polyFeat,
          patialRelationship: "contains"
        };    
      });‍‍‍‍‍‍‍‍‍‍‍‍‍

I have tried the code, but it still does not filter the points by polygon. Maybe there is something I am not considering.

mapView.whenLayerView(featureLayer).then(function(featureLayerView) {

        var polyFeat, query;

        query = distrito.createQuery();

        //query.where = "id_dist='"+ubigeo+"'";          

        query.outSpatialReference = mapView.spatialReference;

        query.returnGeometry = true;

        distrito.queryFeatures(query).then(function(results){

          polyFeat = results.features[0].geometry;

        });

        featureLayerView.filter = {

           geometry: polyFeat,

           spatialRelationship: "contains"

         };    

       });

I made some adjustments and it worked perfectly. Thank you very much for your support

 mapView.whenLayerView(featureLayer).then(function(featureLayerView) {        

        var query = distrito.createQuery();

        query.outSpatialReference = mapView.spatialReference;

        query.returnGeometry = true;

        distrito.queryFeatures(query).then(function(results){

          featureLayerView.filter = {

            geometry: results.features[0].geometry,

            patialRelationship: "contains"

          }; 

        });           

       });
