ArcGIS Pro Attribute Rules Equivalent to NEAREST_FEATURE Function in Attribute Assistant

GISUSER6

ArcGIS Pro 2.7

Hello,

I am trying to set up an attribute rule that will pull from the NAME field of a streets center line layer and populate it into a STREET field in the feature class I am adding the rule to. I know the same function does not exist in Attribute Rules as it does for NEAREST_FEATURE in Attribute Assistant, but I am trying to come up with an Arcade expression to do the same thing. The search distance I want to use is 100 ft. Attached is the snip of the code I started with but I keep getting an error. 

Some guidance would be much appreciated!

Hi @GISUSER6 ,

 

I did a test with a local coordinate system and it will work with some minor adjustments:

 

You will need to:

• Use Buffer instead of BufferGeodetic
• Use Distance instead of DistanceGeodetic
• Place "var" before street in the for loop.

var streetLayer = FeatureSetByName($datastore, "streets_WGS_Project", ["NAME"]);
var searchDistance = 100;
var streetIntersect = Intersects(streetLayer, Buffer($feature, searchDistance, "feet"));
var cnt = Count(streetIntersect);

var minDistance = Infinity;
var name = Null
if (cnt > 0) {
    for (var street in streetIntersect) {
        var dist = Distance(street, $feature, "feet");
        if (dist < minDistance) {
            name = street.NAME;
            minDistance = dist
        }
    }
} else {
    // pass no features found within search distance, name remains null
}

return name;
