Hello,
This same question was asked in 2015 by @BenGrod and now that its 2023 I'm still wondering the same question. I have a survey123 form a user can enter in coordinates that source a GeoPoint question to display a new point, but is it possible in AGOL apps for a user to input coordinates and create a new point on a map that isn't a graphic?
It seems Esri is encouraging people to use web maps for editing/creating data which if so a basic function is to create a new point with coordinates on a map.
I have a need for biologists that want to quality control data by adding in the start/end coordinates of a transect line and then get line length between the points. This data doesn't need to be even saved, but just a visual check. They also see which polygon areas are intersected by the transect.
Thanks for your thoughts,
Kathy
