ArcGIS Online Zone Lookup App not returning correct information for some areas #4

Hi

We are using the zone lookup template app in AGOL for a public consultation that is going live in the next couple of weeks. Unfortunately it does not appear to function correctly; sometimes when you select an area, it does not bring back any information. This has happened on some multi part polygons as well as a donut/island polygon. However, it has also happen in some regulate shaped polygons. Please could you let me know if there is a reason this may be happening. Im sure it worked a few months ago!

Thanks Mark

I have worked out that this is due to the centroid being used the the application not being constrained to being within the polygon. I can't stress enough how much of a showstopper issue this this with this template as in many cases it will return the information for a completely different feature or no feature at all. I can provide examples if this helps.

Thanks Mark

I'm getting this too. Sometimes there are no results when I'm definitely clicking within a polygon.

This is a super annoying feature - I was trying to locate intersecting polygons using a ZIP code boundary layer as the search layer. The application uses the polygon centroid only - agree about the showstopper comment!

As a workaround - I created a random multipoint layer spreading the points within the zip code boundaries evenly. This did work and allowed the search function to hit all intersecting polygons and the UI is very good this way! I would give this a try and see if it works out for those having this annoying issue.
