I would like to create a web app that requires a sign in. I want people to be able to add vector data to a map on their individual accounts for planning purposes but I don't want that data to be seen by other users. Does anyone know how I could do this or know of a company that would provide the service at a reasonable rate to users?
We have similar requirements, so I'll describe our approach. Your requirements may be similar enough to use and/or adjust the approach below.
As the Emergency Manager, I need to access confidential features managed by each business unit so that I can make decisions based on all confidential features that the organization has. Managers in the business units choose whether or not to allow staff in other business units to see the confidential features they manage.
