Populating Data from a Polygon / Geofence

JordanHolt

Good Morning,

I am looking to create polygon layers at several intersections across a city with intersection data. This would include cross streets & intersection ID. I will have field users adding new data through Survey123 to create surveys for all structures in each intersection. To save them time I was hoping to be able to pull data from a polygon I create around each intersection before the field techs start their work. Each new record they create would prepopulate the intersection ID and cross streets. There is a potential of 15-20 surveys per intersection so this will save them a lot of time. How do I get the data to populate form the polygon layer when each new survey is created?

 

Thanks,

Hi Jordan,

You need to publish a feature service of the polygon layer in ArcGIS Online or Portal for ArcGIS and enable editing for the feature service.

Then, in the Survey123 form, create two hidden questions to store the intersection ID and cross streets data. Use the calculation feature to populate these questions with the data from the polygon layer based on the current GPS location of the user's device.

You can use the pulldata() function in the calculation column of the hidden questions to retrieve data from the polygon layer.

Similarly, you can retrieve the cross streets data and populate the relevant hidden question using the pulldata() function.

I hope this helps
