Automatically generate point features at the endpoint of line features in Arcgis Online

[anonymous55]

Hello,

I am looking for a way to automatically add a point to a line when users create a line feature. The point location does not matter, but I want the point to inherit the same attribute values (such as the line date) from the line feature.

I know this can be done in ArcGIS Pro, but I am looking for a way to do it in ArcGIS Online, possibly using Arcade expressions or another workaround.

I’m curious if anyone here has had a similar experience and implemented something like this.

Thanks

Although I haven't tried using these, apparently group templates configured in ArcGIS Pro are supported by the ArcGIS Online Web Editor:

Hi @anonymous55, 

like @MobiusSnake mentioned, you could create and use shared templates to do this. Those need to be created in Pro, and it requires a few extra steps to bring them into ArcGIS Online- we're working to streamline this process in the near future.

If you want to go that route, you can follow these steps:

1. Bring the hosted feature service (HFS) with line and point layers into Pro where you can manage the templates. If you don't already have a HFS, you'll need to create that first.
2. Create a group template in Pro. Using a builder you can configure it to add a point each time you create a line. 
3. Use the command 'Store templates' in Pro. This stores the group template as a shared template in ArcGIS Online. 
4. Add the  HFS to a web map in Map Viewer.
5. Here you could author calculated expressions in the Form to fetch attribute information from another layer. You can do that using a FeatureSet function (see this article for more).
6. Start editing. You'll see the new template in the Editor pane in apps like Map Viewer, Web Editor, and more.
