Issue with Arcade Attribute Rule Script - Not Returning Expected Values

StefanAngerer — Mon, 22 Apr 2024 13:08:02 GMT

Hi everybody,

I'm attempting to develop an Arcade Rule that, given a feature geometry, identifies the closest address feature within a specified buffer distance. The script should then update the created or updated features attributes with the closest attributes of the closest address feature. However, as so often, I'm encountering an issue with the script.

heres the script im using:

var featureGeometry = Geometry($feature) if(isEmpty(featureGeometry)){ return Null } var addressesLN = FeatureSetByName($datastore, 'VG_ADDRESSES_LN', ['*'], true) var addressesPT = FeatureSetByName($datastore, 'VG_ADDRESSES_LN', ['*'], true) var addressesAR = FeatureSetByName($datastore, 'VG_ADDRESSES_LN', ['*'], true) var bufferSize = 20 var bufferPolygon = Buffer(featureGeometry, bufferSize, 'meters') var bufferIntersectingLN = Intersects(addressesLN, featureGeometry) var bufferIntersectingPT = Intersects(addressesPT, featureGeometry) var bufferIntersectingAR = Intersects(addressesAR, featureGeometry) var mostInformativeAddresses = Null if(!isEmpty(bufferIntersectingPT)){ mostInformativeAddresses = bufferIntersectingPT } else if (!isEmpty(bufferIntersectingLN)){ mostInformativeAddresses = bufferIntersectingLN } else if (!isEmpty(bufferIntersectingAR)){ mostInformativeAddresses = bufferIntersectingAR } else { return } if(isEmpty(mostInformativeAddresses)){ return } var closestFeature = Null var closestDistance = 9999 for(var addressFeature in mostInformativeAddresses){ var currentDistance = Distance(featureGeometry, Geometry(addressFeature), 'meters') if (currentDistance < closestDistance){ closestFeature = currentFeature closestDistance = currentDistance } } return{ "result":{ "attributes":{ "ADM_KEY_COMM": closestFeature.ADM_KEY_COMM, "ADM_KEY_STREET": closestFeature.ADM_KEY_STREET, "ADM_KEY_COMMPART": closestFeature.ADM_KEY_COMMPART, "ADM_KEY_ADDRESS": closestFeature.ADM_KEY_ADDRESS, "ADDRESS_TEXT": closestFeature.ADDRESS_TEXT } } }

The script validates without errors, but it doesn't return any values, even though there is a valid address feature within a reasonable distance.

Can anybody help me find the issue here or suggest any improvements to the script?

Any assistance would be greatly appreciated!

Thanks,

Stefan

Hi Stefan,

It does not appear that you are using the buffer polygon created from $feature. Try updating the Intersects calls to use the buffer.

All three featuresets are pointing to the same class, you want to fix that. I revised the logic, code below. I think you want something like this.
