"Hidden Cities are hidden unless a character is flying in atmosphere above the city"
Given that, does that mean directly above the city? i.e. If I wanted to check for hidden cities, would I have to fly to each planet square in atmo to check? Or, would that include my scanner range?
i.e. If I am in atmo at 0,0 and there is a hidden city at 0,1 (given sensors = 8 ) would it show up?
