We use Survey123 mainly in web forms. Now since it's possible in Experience Builder to auto-populate the form with the attributes and geometry of a selected feature in the map, we built a 'report a bug' feature around it. In case users forget to select a feature (which is a hidden field in the form that auto-populates), we placed an additional 'Upload Screenshot' functionality to the web form (basically an upload image type question). However, it's just possible to upload a previously stored image file from your PC. It would be much more conventient to just replace the 'Take a photo' button with a 'Take a screenshot' button that takes a screenshot and directly adds it as an attachment to the form. ... View more

We're working quite a lot with 3D scenes...I recently got an integrated mesh where I placed our polygons on top of it and created labels with callouts to make them stand out better - it's a fantastic tool. Now I wanted to do the same in another scene (both times it was a 2D polygon feature), and this callout size feature is just not available? Have a look at my screenshot: Only difference with the one scene where it's not available is that I did quite some extensive symbology editing in Arc Pro before uploading everything - which was quite unsuccessful, since almost none of my symbology considerations were adopted in the Scene... Also the upper half of the image where it's not available was taken in Enterprise, the bottom half on AGOL. Is this just a feature not available on Enterprise? I'd be very surprised, since it seems to be such a basic functionality. ... View more

This blog post from July 2019 mentions all the restrictions that come with using Survey123 from an Enterprise Portal. With Enterprise 10.8.1 Esri lifted the restriction of not being able to use attachments in the feature service. Unfortunately it's still not possible to use the feature report service from Portals with Integrated Windows Authentication. So my suggestion: either integrate the feature report service directly in the Enterprise installation of Survey123, or lift the restriction to not being able to use this service from the Portal with IWA. ...

We are looking into more low cost GNSS rover devices which unfortunately only measure ellipsoidal heights. To use those for mapping applications, we have to post-process those heights to receive orthometric heights (MSL). I have now received an official ascii grid file with the geoid undulation values. The distance between each point feature is between approx. 750 and 900 m: Would it be a viable approach to correct the height from ellips. heights to MSL by performing a nearest feature search and then subtract the geoid undulation from the ellips. heights? And if this is a viable way to do so in order to get proper MSL heights, would it be smarter to rasterize the grid first in order to increase the performance (ultimately this should end up in a web tool). What would be a suitable raster size if point spacing varies between 750 and 900 m? ... View more
