Reverse Geolocating points

3CDCOrganizationalAccount

I am trying to reverse geolocate addresses from geopoints generated from Survey123 forms. I found a blog that reviews how to use reverse geolocation in survey 123, but when I tried it the new address field did not update. For reference, I put  pulldata("@geopoint",${location},"reversegeocode.address.Match_addr", ${companyLocator}) under the calculations column. The survey did not respond with an error when saved.

Hi @3CDCOrganizationalAccount,

Thanks for sharing your XLSForm. Having a look at the xlsx file, it appears you first created this on the website (web designer) and are now using Connect? Was there any reason for this?

I do not see any reverse geocoding calculations in the Form 3.xlsx file or Businesscheck_Form.xlsx contained in the ZIP file. Which form are you are using and modifying? And which question/field are you trying to update with geocoded address?

Can you provide the exact user workflow you are wanting to achieve? For example, do you want the user to select a point on the map in the geopoint (or use their current GPS/network location) and from that geopoint (lat/long) do a reverse geocode to get the geocoded address? If so then using the following will work:

pulldata("@geopoint",${location},"reversegeocode.address.Match_addr")

In this case, the default locator service for your organization will be used. However if you have a specific locator service you want to use (not the default one in your org), you need to use the additional parameter with the URL of the locator:

pulldata("@geopoint",${location},"reversegeocode.address.Match_addr", ${locatorURL})

If the service is secured, or the survey is intended for public users, a proxy item must be configured with access credentials saved in it.

I added a text question to your xlsx file and used the above pulldata() example, and it works as expected. See below screenshot. When I select a point on the map, the text question is updated with the geocoded address. I am using the default locator service (ArcGIS World Geocoding Service).

Hope this helps,

Regards,

Phil.
