These are basic "battle maps" for designing your own missions.
The EEZ stuff is mostly for air traffic but you can assume they also mark areas of interest for a given country. For example, you wouldn't want to stage a mission between Spain and Argentina in the middle of the Great Lakes. This is just an easier way to figure out where flash points could occur.
Freedom Of Navigation can get tricky. Are you assuming everything is peaceful or are the tensions mounting?
