Probably multiple ways to handle this, but I need to set a definition expression on a polygon FeatureLayer using the intersection of another polygon FeatureLayer.

James, A Query class has a where property and a geometry property. You may be use to using the where but you can also just use the geometry property instead or or in addition to the where property. createFuncLocLayer : function ( ) { this . funcLocLayer = new FeatureLayer ( this . config . functionalLocationLayer ) ; var def = new Deferred ( ) ; if ( ! this . workplanBoundaryLayer . loaded ) { this . workplanBoundaryLayer . on ( "load" lang . hitch ( this , function ( ) { def . resolve ( this . workplanBoundaryLayer . graphics [ 0 ] ) ; } ) ) ; } else { def . resolve ( this . workplanBoundaryLayer . graphics [ 0 ] ) ; } def . then ( lang . hitch ( this , function ( result ) { var geom = result ; var wpGeometry = geometryEngine . geodesicBuffer ( geom , - 20 , "meters" ) ; var query = new Query ( ) ; query . outFields = [ "*" ] ; query . returnGeometry = true ; query . outSpatialReference = this . map . spatialReference ; query . geometry = wpGeometry ; this . funcLocLayer . queryIds ( query , lang . hitch ( this , function ( objectIds ) { var qStr = this . funcLocLayer . objectIdField + " IN(" + objectIds . join ( ',' ) + ")" ; this . funcLocLayer . setDefinitionExpression ( qStr ) ; } ) ; } ) ) ; . . . }

Hi James,

I haven't tried this out but I think you have to use FeatureLayerView or execute a query on the FeatureLayer and create a layer for visualization from the results?

Let me know if this helps.

I have two polygon Feature Layers:

FeatureLayer1 always has a single(1) polygon feature.
FeatureLayer2 has thousands of polygon features.

Requirement: Apply definition query/expression to FeatureLayer2 so that the only features available (throughout the entire session) in the map are those that intersect with the single polygon in FeatureLayer1.

rscheitlin

James,

Maybe you better explain your workflow.

JamesCrandall

hmm. So I will need to first select on funcLocLayer, collect OID's and then use those to setDefinitionExpression on that same FeatureLayer?

rscheitlin

James,

You can not use a Geometry in a layers definition expression. What you have to do is turn that geometry into a sql expression. So you use the geometry to query the OIDs of the layer that intersect (or what ever spatial relationship you want) and then send that array of ObjectIds to the layer definition expression.
