Fetch Attribute From Nearby Feature on Field Maps

Hi,

I have been trying to do the fetch attributes from nearby features arcade code that I have seen on blog, github and various other community posts by @Anonymous User . I cannot get it to work for my field map.

// If feature doesn't have geometry return null if (IsEmpty(Geometry($feature))) { return null } // Get the parcels layer var parcels = FeatureSetById($map, /* Yurok Addresses */ "17d69e9a280-layer-9") // Buffer the current location and intersect with parcels var bufferedLocation = Buffer($feature, 3000, 'feet') var candidateParcels = Intersects(parcels, bufferedLocation) // Calculate the distance between the parcel and the current location // Store the feature and distance as a dictionary and push it into an array var featuresWithDistances = [] for (var f in candidateParcels) { Push(featuresWithDistances, { 'distance': Distance($feature, f, "feet"), 'feature': f } ) } // Sort the candidate parcels by distance using a custom function function sortByDistance(a, b) { return a['distance'] - b['distance'] } var sorted = Sort(featuresWithDistances, sortByDistance) // Get the closest feature var closestFeatureWithDistance = First(sorted) // If there was no feature, return null if (IsEmpty(closestFeatureWithDistance)) { return null } // Return the address return `${closestFeatureWithDistance['feature']['ADDNUM']} ${closestFeatureWithDistance['feature']['ADDRESSNAM']}`

I get the error "failed to calculate" every time. We are surveying for water tank placements and trying to make it easier on our fieldworkers. If all else fails, I will have them write it in or create a domain but would prefer to have it auto populate.

Should I change "ADDNUM" and "ADDRESSNAM" to something within my layer? Attached is a list of field names for my Address layer. I could just use "Full Address" or "Label" instead of "Address_number" and "StreetName"

I read on one post that it could be because of the spatial reference but that was supposed to be fixed in the last release and I am not getting that same error message. I am still fairly new at Arcade but was able to implement a code for the child table auto population from this parent layer. If I can get this next one to work correctly, it would be incredibly useful in other projects.

Hello

You just need to change this line of the code

return `${closestFeatureWithDistance['feature']['ADDNUM']} ${closestFeatureWithDistance['feature']['ADDRESSNAM']}`

To this

return `${closestFeatureWithDistance['feature']['Address_number']} ${closestFeatureWithDistance['feature']['StreetName']}`

also you need to paly with buffer number to get result.
