I have a set of polygons (municipal boundaries) and a point layer. I'd like to (eventually) create a WebApp to show the number of points inside each municipality, but that point layer is going to be constantly updated (most likely each week).
I know a one time fix is a spatial join with number of intersection points as an attribute, but I was wondering if there was any method to query this sort of function to change as the point layer changes.
I want the symbology to update even if I add filters to the map. I could Python script it but that would only be for each write, where I want it to be truly dynamic.
Processes are planned to be done in ArcGIS Pro, but final product will be in ArcGIS Online
