I have a Web Map in ArcGIS Online that contains a point layer and a DTM Imagery Layer with Elevation data. This imagery layer is from ESRI, from the browse to add layers tool. On the point layer, I have a Field Maps form, and I would like to use Arcade to auto-fill a field of the point feature with the elevation data from the Imagery Layer at that location.
I found a similar question here: https://community.esri.com/t5/arcgis-online-questions/arcade-for-calculate-a-difference-between-the/... but it's not quite the same, though I don't have much hope from the result of that question.
The alternative option would be to use Pro after the points have been created, and use a script or certain tool to do the same thing. Would either of these options be possible?
