Overwrite Coded Text Values with Different Text String on Intersect in Arcade Expression

DanE897645198

Hi, I am attempting to create an attribute expression through an address point layer that intersects a zoning layer. The zone layer has an attribute that is coded with different zones, i.e. "RR" for residential, "CG" for commercial. I'm using Intersect to find the polygon layer and retrieve the attribute but having an issue with re-writing the return result. I used the code below but am having an issue with the open brace { at the switch line in code below (line 10 in the image). Any help would be greatly appreciated!

// Variables for the layers

var point = $feature;

var polygons = FeatureSetByName($map, "COG Zoning");

// Initialize the output string

var result = "No intersection";

// Loop through polygons to check intersection

for (var poly in polygons) {

    if (Intersects(point, poly)) {

        // Customize this part to return specific text based on polygon attributes

        switch (poly.Pro_Zoning) {            

          case "RR":

                result = "Residential";

                break;

            case "CG":

                result = "Commercial";

                break;

            // Add more cases as needed

            default:

                result = "Zoning data is not available";

        }

    }

}

// Return the result string

return result;

And did you try swapping the switch/case for Decode?

Also, rather than loop through the entire polygons layer and checking for intersection with your point, you're better off doing it the other way. Using Intersects between your point and the entire polygons layer will return a FeatureSet of only those polygons which intersect with the point.

var intersecting_polygons = Intersects($feature, FeatureSetByName($map, 'COG Zoning'))

// if intersection, decode value, otherwise return "no intersection"
if (Count(intersecting_polygons) > 0) {
  var poly = First(intersecting_polygons)
  return Decode(
    poly.Pro_Zoning,
    'RR', 'Residential',
    'CG', 'Commercial',
    //etc
    'Zoning data not available'
  )
} else {
  return 'No intersecting zoning feature'
}
