Zone Lookup Zoom Level

ArielLow2146 — Fri, 29 Jul 2022 20:23:43 GMT

I am trying to configure a Zone Lookup app using the "Features within zone" option. I've selected a polygon layer to use as the search zone and a point layer to include in the results.

I've configured the search to use the ArcGIS World Geocoding Service and the same polygon layer I configured for the search zone.

I'm getting the results I expect but regardless of which search source I use the map does not zoom at all. I've tried editing the search source to change the zoom scale but this doesn't seem to make any difference.

The behavior I would expect is the map would zoom to the extent of the search zone polygon. Is there a way to achieve this?

The zoom settings in the search source configuration does not override the app settings to zoom to the extent of the polygon. We are planning to add a setting in the next update of ArcGIS Online that would allow app creators to set a specific zoom scale after the search (to override the default polygon extent). Are you able to share a live example where the map is not zooming to the extent of the largest polygon in the search?

@BethRomero do you have an ArcGIS Online username I could add to a group?

@BethRomero I've invited you to the group with the app that is not zooming to the extent of the search zone polygon

Thanks for sharing your map. When the search polygon is not included in the results it looks like the app is staying at the current scale, if the polygon is included as a result option it will zoom. I've logged an issue for the zoom not occurring when the polygon is not included with the results.

Thanks @BethRomero! I just tested it out and can confirm the zoom does happen when the polygon is not included in the results.

I appreciate you logging the issue. It would be great if the result polygon was automatically included at the top of the results panel so folks know which polygon they're seeing results for. When I include the search polygon layer in the results is is down near the bottom of the list because I don't want the polygon layer to be in the layer list above the points layers.

Hi Beth,

Has the ability to allow app. creators to set a specific zoom scale after the search (to override the default polygon extent) been implemented in the zone look up instant app? I see there was a new AGO release in June 2023. I didn't see that functionality listed in the blog that discusses the changes in the newest release. My zoom settings aren't being honored in the app. even though I am using the search polygon in the result option list.

@MollyWatson1 You can override the default scale by setting a specific scale level. This setting is located in the full setup of the app in the Zone Lookup section > Style Results subection > Set scale level. Another way to find settings is to use the Search Settings option (top left corner) and search "set scale". Once there you can define the scale level you'd like to be set after every search.

Hi Beth,

Thanks for the additional information. When I set the scale setting under the Style Results section, the scale setting isn't honored after the search is made. The map zooms to the same level, which is the parcel level. Here's a screen shot of my results:

Scale setting set to city zoom levelMap zooms to parcel level after search instead of city level as specified in the scale settings

You can see I set the scale setting to city, but the map zooms to parcel level after the search instead of city level.

@MollyWatson1 - did you ever figure out how to get the Instant App not to zoom to the parcel level? April 2024, I still experience the same issue.

No, I did not get it figured out. It does not appear to work the way it is supposed to.

Are you trying to set the app to zoom out to a smaller scale from what it would be? Is there any way you are able to share your application?

Hi Beth, the apps are already shared publicly. You can view one of them here: https://bouldercounty.maps.arcgis.com/apps/instant/lookup/index.html?appid=b4a5c722b4b04cbabdfdea187f79a4b4
