I am looking for a process on how I may deploy an experience builder web app/map that allows a user to filter 2 mosaic datasets to a time stamp of their choosing and the resultant view they see is a minus of the 2 surfaces.
Where i am up to is.
1)I have a dynamic raster service that is connected to a mosaic dataset that contains a few 1000 elevation captures
2) Said service is loaded into a web map twice as "Latest Surface" and "Historical Surface"
3) Filter widget is set to allow user to filter both "Latest Surface" and "Historic surface" to a capture of their choosing
4)????? What do I need to do to get a subtraction to work dynamically as the user changes the filter?
