Survey123 for ArcGIS is a simple and intuitive form-centric data gathering solution that makes creating, sharing, and analyzing surveys possible. In this webinar, we will discuss some of the most recent updates to Survey123 such as authoring surveys through a browser and croudsourcing data.
Can you add more than one photo?
No, you cannot add more than one photo through the web app at the moment (as of November 2016). However I would imagine this is something that is being worked on. The idea is that these kind of web apps will also be created using Survey123 Connect. At the moment they can only be authored using the Survey123 website.
Can you modify a published survey?
No you cannot currently modify a published survey (as of November 2016). However, you can open an existing survey and use the 'Save As' option to create a replica of an existing survey.
Does that mean we can launch a survey 123 form from say inside ArcGIS collector to open a 123 form. If so can you pass a reference so you can link information back?
Yes. Check out Survey123's custom URL Scheme to get this setup. Similarly you can call Navigator and Collector from the various apps as necessary.
Missed the start of webinar but would like to see a possibility of taking the survey to a second stage following revisit to a said location etc. Looking forward to seeing how it can be used with an existing service. Will one be able to use an existing webmap that is IG or ITM?
At the moment, the ability to edit existing features is not possible. However, support for editing workflows is something that is being worked on as was noted in the blog post regarding the last release.
I don't think IG or ITM will be supported for a while given that you can only use Web Mercator at the moment. Hopefully it is something that will be supported at some stage in the future.
