Hello, is it possible to have an event layer with AGOL?
The simplest example is a CSV of XY points stored in a file at Online.
I want that when I replace the CSV, the layer will reflect new points.
Ensure the CSV file is shared with everyone (public).
You need to add the CSV as a layer using "Add Layer from Web" option.
For the URL, you need to provide the URL from the Item Details page of the CSV.
Then you can create the desired web maps and web apps.
For updating the CSV, use the Update option in Item Details page of the CSV.
Note: Do not delete the CSV file from My Contents in order to update it.
Also note that the extent of the map might not change automatically. You might need to change the map extent, if it is different from the extent of the previous CSV.
Below are the snapshots of my app with original and updated CSV respectively (Just refreshing the Application URL manifests the changes).
