I have a form that would be easy enough to add a Z property in the geopoint. However, doing so requires edit to the XLSform and makes it so the drag/drop designer is no longer functional.
Is there a way to accomplish something similar by getting altitude based on latitude and longitude in the Calculate field in the web-based designer?
Ideally getting the Z value would just be part of the default geopoint property, especially since the iOS app already retrieves it. But, that's another topic.
@bryandhughes, by any chance did you try to implement that with Survey123 Connect to obtain Z-Values from the tablet?
