Popup Arcade Expression to display a count of different point features that appear in a selected polygon

TobyStewart2 — Sat, 02 Jul 2022 02:43:01 GMT

I am quite new to Arcade and am stuck trying to create a custom popup in ArcGIS Online.

I have a Local Government Polygon layer for the state and three other point layers:

1. Gasworks

2. Landfill

3. Waste

I am trying to create a popup that will display the total number for each of the 3 sites in that selected Local Government polygon.

I have tried using the Count & Intersect functions but can only get it working for one of the 3.

Any help would be greatly appreciated!

var gasworks = FeaturesetByName(...) var gasworks_in_state = Intersects($feature, gasworks) var landfills = FeaturesetByName(...) var landfills_in_state = Intersects($feature, landfills) var waste = FeaturesetByName(...) var waste_in_state = Intersects($feature, waste) var point_counts = [ `gasworks: ${Count(gasworks_in_state)}`, `landfills: ${Count(landfills_in_state)}`, `waste: ${Count(waste_in_state)}`, ] return Concatenate(point_counts, TextFormatting.Newline)
