Calculate Multiple Fields from multiple Intersection poly layers using Attribute Rules

JustinNettleton1 — Tue, 23 Aug 2022 19:13:54 GMT

I am setting up some attribute rules to populate fields in my NG911 address database. A Lot of these fields are populated off of interests of 3 different polygon layers. I have them all set up as multiple rules now and they are working, but editing is very slow.

I know I can combine these rules into one, just not sure how to do it when I am intersecting multiple layers to populate different fields.

Can some one point me in the right direction or have a sample for me?

Thanks,

Justin

Basically, instead of choosing a field for the Attribute Rule and returning a value, you leave the field empty and return a dictionary. The possible keys of this dictionary are described here: https://pro.arcgis.com/en/pro-app/latest/help/data/geodatabases/overview/attribute-rule-dictionary-keywords.htm

var attribute_1 = null var attribute_2 = null var attribute_3 = "Nothing here" var layer_1 = FeatureSetByName($datastore, "FC_1") var id = $feature.SomeID var polygon_1 = First(Filter(layer_1, "SomeID = @ID")) if(polygon_1 != null) { attribute_1 = polygon_1.Attribute } var layer_2 = FeatureSetByRelationshipName($feature, "Relationship") var polygon_2 = First(layer_2) if(polygon_2 != null) { attribute_2 = polygon_2.Attribute } var layer_3 = FeatureSetByName($datastore, "FC_3") var polygon_3 = First(Intersects($feature, layer_3)) if(polygon_3 != null) { attribute_3 = polygon_3.Attribute } return { result: { attributes: { Attribute1: attribute_1, Attribute2: attribute_2, Attribute3: attribute_3, } } }

Also, a lot of the slowness of Attribute Rules comes from the loading of FeatureSets. To make it quicker:

Load only the fields you need.
Don't load the geometries if you don't want to work with them. You can do an Intersects() without loading the geometry!

Thank you for these solutions. They have helped the performance.
