I am having a hard time understanding how to achieve this. We are using the reporting hierarchy (Rep reports to manager, manager to director) and we are doing this based on a teams location, they are all in different areas. We want them to only be able to see what belongs to them in all modules, Leads, Meetings, Deals, Tasks (Contacts can stay open to everyone). 

I have been struggling to figure out how to achieve this using the data sharing settings. Any help would be wonderful.
