I have a WebApp that has a hospitals layer and I want to be able to use the Find Nearest geoprocessing tool/widget to find the closest hospital to a location. That location needs to be added by the user on a use by use basis. I have tried the add data widget, but it creates a temporary layer that can not be used by the Find Nearest widget. I am in the processes of trying to add a geoprocessing tool online that will add an xy point, but I want to know if that will add a layer that is usable by the Find Nearest widget? Is there an easier way of adding a location that can be used as input for the Find Nearest widget?
