Field calculates point intersecting polygon

TL2 — Wed, 20 Aug 2025 18:38:28 GMT

Is there a simple day to grab attribute data from a polygon fc that intersects with a point fc. I need to update points based on what polygon layer name they intersect.

Right now, I am doing a spatial query and then attempting to field calculate but I feel like there is an easier way.

I need to do this in an AGO notebook but here is my arcade expression

var inter_trust = count(Intersects($feature, trust)) if (inter_trust > 0) { return "Trust"; }

Hi @TL2, here is an example on how to do an intersect using the ArcGIS API for Python:

from arcgis.gis import GIS from arcgis.geometry import filters # Connect to AGOL gis = GIS('home') # Reference services ptFeatureLayer = gis.content.get('cd10146a4a91477b928f0921957b9698') polygonFeatureLayer = gis.content.get('c44daed09ff14f80b000b541653aa1fc') # Get point layer ptFeatures = ptFeatureLayer.layers[0] # Get polygon layer polygonFeatures = polygonFeatureLayer.layers[0] polygonFeatureQuery = ptFeatures.query(where='1=1') # Perform intersect for polygon in polygonFeatureQuery: queryResult = ptFeatures.query(where='1=1', out_fields="division", geometry_filter=filters.intersects(polygon.geometry)) division = queryResult.features[0].attributes['division'] print(division)

You can join points and polygons to get attribute data based on location. See arcgis.features.GeoAccessor.join. Also, here is an example where points are joined to polygons from the Python API documentation: Example: Merging State Statistics Information with Cities. This should be applicable to your situation.
