ArcGIS Survey123: Advanced Topics 

you can enhance the accuracy using an external GPS or GNSS device

Hi Juma, thanks for watching! To answer your question, we have two suggestions: if the form is being created for submission via the web, you can create a rating question directly within the web designer. If the form is being created for use with the Survey123 mobile application, we would suggest using a Likert question (select_one with likert appearance if creating via Survey123 Connect). You can post any other questions you might have here on the Survey123 GeoNet page: community.esri.com/groups/survey123

Hi Alex, thanks for watching! To answer your question, we don’t support direct auto-incrementing within Survey123 due to the complexity of ensuring unique numbers with multiple people collecting data in disconnected environments. That being said, we provide guidance on creating unique ID numbers in this GeoNet blog post: community.esri.com/groups/survey123/blog/2017/11/25/creating-ticket-numbers-in-survey123-for-arcgis . We hope this helps, Alex!

Hi again Juma- there are a couple of methods to accomplish unique identification, depending on your specific workflow. First, Survey123 generates a unique ID for each record submitted, though the ID generated is not designed to be human readable; additional unique values of this type (known as uuids) can be generated. Second, if you need a human-readable unique id, one method to generate it is by creating an ID based on the timestamp of the survey; it becomes extremely unlikely that surveys are created within the same millisecond. Finally, there are a couple of methods where an ID entered can be validated against the list of already submitted IDs, if neither of the first two methods solve your issue.

With the new beta version (3.4 or newer) you can!
