Say there is base polygon A and when the user edit polygon B over the multiple polygon A, the polygon B gets intersected/splited based on polygon A (please see the attached figure). So far I can do inside the base polygon but is there way I can query to obtain the geometry outside of the base polygon Is there any code snippet or sample/template to achieve this task?&nbsp;</P><P>Here is my snippet:</P><P>IntersectingPolygon.on("edits-complete", modifyFeature);</P><P>function modifyFeature(evt) {<BR /> var queryFeatureWithId = new Query();<BR /> queryFeatureWithId.objectIds = [evt.adds[0].objectId];<BR /> queryFeatureWithId.outFields = ["*"];<BR /> queryFeatureWithId.num = 1;<BR /> queryFeatureWithId.outSpatialReference = map.spatialReference;<BR /> queryFeatureWithId.spatialRelationship = Query.SPATIAL_INTERSECTS;<BR /> queryFeatureWithId.returnGeometry = true;<BR /> <BR /> var addedFeature = null;<BR /> var addedFeatureObjectId = evt.adds[0].objectId;<BR /> <BR /> //use the feature's object id to get the feature's geometry<BR /> IntersectingPolygon.queryFeatures(queryFeatureWithId, function(featureSet){<BR /> if(featureSet.features.length == 0) {<BR /> return; <BR /> }<BR /> addedFeature = featureSet.features[0];<BR /> <BR /> var queryOverlappingOuterPolygon = new Query();<BR /> queryOverlappingOuterPolygon.geometry = addedFeature.geometry;<BR /> queryOverlappingOuterPolygon.num = 1;<BR /> queryOverlappingOuterPolygon.outSpatialReference = map.spatialReference;<BR /> queryOverlappingOuterPolygon.spatialRelationship = Query.SPATIAL_REL_RELATION;<BR /> <BR /> //query overlapping feature on ExistingPolygon<BR /> ExistingPolygon.queryFeatures(queryOverlappingOuterPolygon, function(overlappingFeatureSet) {<BR /> if(overlappingFeatureSet.features.length == 0) {<BR /> return;<BR /> }<BR /> var differenceGeometry = geometryEngine.intersect(addedFeature.geometry, overlappingFeatureSet.features[0].geometry);<BR /> //modify added feature geometry so that the feature resides within the boundary of outer polygon feature<BR /> addedFeature.geometry = differenceGeometry;<BR /> IntersectingPolygon.applyEdits(null, [addedFeature], null);<BR /> <BR /> var queryOverlappingInnerPolygon = new Query();<BR /> queryOverlappingInnerPolygon.geometry = addedFeature.geometry;<BR /> queryOverlappingInnerPolygon.outSpatialReference = map.spatialReference;<BR /> queryOverlappingInnerPolygon.spatialReference = Query.SPATIAL_INTERSECTS;<BR /> <BR /> <BR /> });<BR /> <BR /> });<BR /> }</P><P></P><P>Thanks,</P><P></P><P>Kush</P></BODY></HTML> Wed, 31 Jan 2018 20:50:22 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/get-intersected-polygons-geometry-based-on/m-p/716792#M66613 KushendraShah1 2018-01-31T20:50:22Z Re: Get intersected polygons geometry based on polygon https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/get-intersected-polygons-geometry-based-on/m-p/716793#M66614 <HTML><HEAD></HEAD><BODY><P>I have some progress on intersecting the polygon inside of multiple polygon but I want to split into individual&nbsp;geometry with respective objectID.
